Scheme of the heating system on 2 floors of houses. Heating in a two-story house: upper and lower wiring, one-pipe and two-pipe system, installation features

For owners of private houses and low-rise cottages, the problem of choosing between centralized and autonomous heating it’s not worth it - the advantage is clearly on the side of gas or solid fuel boilers that work only for heating private housing construction. This method is much more efficient, more frequent and economical, and its own heating system allows you to adjust the temperature in each individual room in accordance with your requirements. Therefore, the main task is to choose the right heating scheme. two storey building, for example, like this:

Calculation of heating of a 2-storey building

Calculation of energy efficiency, heat transfer and technical parameters heating determines its performance, the amount of heat loss in the house, the power of the heat generator, the number of radiators, their location, etc.

The performance of the boiler, which provides efficient heating two-story house, is calculated from the overall results of heat loss in the building. The initial data for calculations should include:

1. The area of ​​each of their heated rooms and the total area of ​​all rooms in the house.
2. Climatic and geographical features of the area.
3. Thermal insulation of the building and each room.
4. Building materials from which load-bearing walls are built, interior partitions, ceiling and other ceilings, as well as their thickness.
5. The constructive solution of the roofing system, the presence or absence of an attic, an attic, an over-ceiling technical place.
6. Dimensions of windows and doors, the quality of their insulation.

What is the heating system

Electric, solid fuel, liquid fuel, gas heat generator is the main node in the heating system and in the circuit with hot water supply. The average standard boiler output is 100 W/1 m 2 of area with ceilings ≤ 3 m high in an insulated room. The boiler must have a power reserve ≤ 20%. When organizing hot water supply, the power reserve should be increased to 45-50%.

The body of any heating boiler one-story house with natural circulation or with forced circulation, it can be cast iron or metal. The heat generator itself can be mounted on the wall or stand on the floor. The floor unit is recommended to be mounted either in a separate building or in a separate isolated room. This room must be equipped with ventilation, a boiler for hot water supply, a chimney must be installed.

If a heating project for a two-story house with a wall-mounted gas unit is being developed, then a chimney channel is not needed. It is also not necessary to comply with the requirement to install the unit in a separate building or room. Boiler in two-story house with one circuit only works for heating the building. If a do-it-yourself heat generator of a two-story private house is also designed to produce hot water (DHW), then a two-circuit unit is installed.

Energy from the heat generator is transferred to pipes and batteries in two ways: heating with natural circulation or heating with forced circulation of the coolant through the heating pipes of a two-story house. Modern models 2-circuit boilers have their own pump that circulates heated water or antifreeze, and are equipped with an expansion tank closed type.

The radiator is a product made of bimetal or anodized, it can also be made of aluminum, steel, cast iron. The heat transfer coefficient and the degree of inertia of the radiator are directly dependent on the dimensions and materials from which the device is made. Dimensions are determined by the number of sections, their standard number is seven. Also, for the operation of the radiator, a Mayevsky crane, shut-off valves (valve) and a thermostat must be installed on it.

Where it is recommended to install the battery is usually indicated in the passport to it. These are window openings (under window sills), about entrance doors and calculated places around the perimeter of the room. Radiators are connected to risers and heating pipes in a two-sided or one-sided way diagonally, from above or below. The type of connection determines the performance of the battery.

Any heating schemes for a two-story house with natural circulation or forced water movement are calculated for a certain number of batteries (I), and their number is determined by the following formula:

I \u003d S x k 1 x k 2 x k 3 x k 4 x 100 / P (units), where

• S is the area of ​​the heated room in square meters;
• P is the performance of one section of the battery (W);
• K I - coefficient applied to double-glazed windows;
• K II - heat loss coefficient applied to external walls;
• K II - coefficient, the value of which depends on the roofing system - its method of insulation and design;
• k iv - coefficient, the value of which depends on the height of the ceiling (k iv \u003d 1 if the ceiling height is ≤ 2.5 m).

Heating pipes ensure the movement, distribution and return of hot water to the heat generator. The value of the flow resistance is determined by the smoothness of the inner surface of the main and the chosen method of water movement - the heating scheme of a two-story house with forced circulation or the heating system of a two-story private house with natural circulation. Each heating scheme of a 2-storey private house must be airtight, which is ensured by the quality of the piping.

An expansion tank, which is equipped with a two-pipe heating system of a two-story house of a closed or open type, is needed to maintain the required volume of water circulating in the pipes. A sharp heating of the coolant is an increase in its volume, and excess liquid is squeezed out into the expansion tank.

The tank has an air chamber and a chamber for the coolant, which are separated by a membrane. Closed circuits are mounted so that the tank is mounted on the return line, in front of the pump suction. But such a design should provide for mounting the tank at a height of ≥ 1 m.

An open-type expansion tank is mounted in the high point heating system. The volume of the tank must have a 10% volume reserve. Starting point volume is considered the total displacement of the coolant in the pipes. The disadvantage of this design is the rapid evaporation of water from the tank.

Shut-off valves help to mount heating circuits in such a way that they can be repaired or serviced without turning off the heating completely. Taps or valves may cut before or after any appliance or component requiring further maintenance, as well as at the inlet of the system.

Safety and check valves, auto air vent, shutoff valves for pressure balancing are called safety. These devices protect the heating route from water hammer and sudden jumps in the speed and pressure of the coolant. The shut-off valve shuts off the gas (electricity, supply of another type of fuel) as soon as any of the sensors, such as a gas analyzer, or the pump stops working.

Electromechanical or electronic valves, thermostat is a control valve, which is designed to stabilize the operating parameters of the heating circuit.

Hydraulic, thermodynamic arrow, collector - for branching hydraulic circuits, reducing heat loss, increasing water permeability and distributing heat throughout the radiator network. Control devices and equipment are usually mounted next to the collector.

The pump in the heating system of a private house is necessary to move water along the heating main, its presence is an opportunity not to comply with the slopes and geometry of the line, which is required by a heating system with natural circulation.

Various heating solutions

How the single-pipe heating system of a two-story house is arranged, the diagram is shown below. The principle is to sequentially turn on heating devices. Fluid flow will be stable if pipes Ø ≥ 32 mm are used. With such a diameter of the pipe line, the gravitational heating system of a two-story house will also work well, that is, without a pump.

Due to the difference in temperature and pressure at the beginning and at the end of the pipeline, the movement of water will be slow but constant. The disadvantage of such a scheme is that each subsequent battery will be colder than the previous one. Therefore, before you make heating according to a 1-pipe scheme, calculate the total length of the pipes. How longer trunk the less efficiently it will heat the house.

Also, the first option is better known as the Leningrad heating system (scheme for a two-story house or a one-story building). To increase the efficiency of the circuit, you can embed a pump, valves with thermostatic valves, install a bypass.

Do-it-yourself two-pipe heating in a two-story private house is arranged according to the principle of dividing the supply and return fluid flows. The circuit of such a circuit requires parallel connection of the input and output of heating batteries. The water temperature in the sections will always be the same, and the stable operation of the heat generator does not depend on the distance and length of the pipeline.

If you make heating according to a 2-pipe scheme, then inserting taps and thermostatic valves will help maintain and repair units and individual sections without completely shutting down. If, however, a hydraulic arrow with a coplanar-type manifold is included in such a scheme, then all additional circuits can be divided.

Collector wiring connection

Beam wiring (star) is a collector heating system for a two-story house, which provides for the radial laying of pipeline pipes and the connection of autonomous circuits to them. If you observe the same length of wiring in the house, then the hydrobalance will be stable, heat transfer will increase, and the resistance in the pipes will decrease. The correct flow calculation will be observed when installing control valves and a pump in each of the connected circuits. The disadvantage of the scheme is the high consumption of building materials, high labor costs. Advantages - precise adjustment of each radiator, high efficiency, easy maintenance.

How to correctly and evenly distribute the coolant in height

The supply of water from the bottom up in the heating circuit in a private house on two floors is, first of all, connecting the risers on the ground floor or in the basement. A 2-pipe circuit is a made parallel supply and return route. Water moves up and, passing through the batteries, begins to move down to the boiler. The supply pipes must end above the batteries of the second floor. The entire supply line must have a common air bleed valve. Each radiator has its own Mayevsky crane.

The wiring with the top heating connection is the movement of water from top to bottom. Through the main supply pipe, water enters the looped wiring or dead ends of the circuit. Supply to the radiators is carried out from the attic insulated room. Further, along vertically mounted pipes, water enters the common return line and through it into the heat generator jacket. At the design stage of such wiring, it is necessary to take into account the location of the pump - it must be included in the return pipe in the immediate vicinity of the boiler. It is necessary to use a circulation pump in this connection option, otherwise there will be no movement of the coolant, except for the first radiators.

Two-pipe heating of a private house in a vertical design with any supply connection option requires constant monitoring of the balance of pressure and temperature. But if the conditions of control and adjustment possibilities are provided, the system will work stably both in terms of maintaining the desired pressure and in terms of compliance with temperature regime.

It is quite simple to study and understand how the heating of a private house works. It is more difficult to do all the work yourself and for free, so the help of professionals here will not hurt.

Before every homeowner who has decided to make the right heating in his two-story house, the question of choosing the type of system initially arises. There are several options for traditional and new schemes, but in order to choose one of them, you need to understand the essence of the issue a little. The purpose of this article is precisely to consider what the heating scheme of a two-story house is, to reveal the pros and cons of each type of system.

Single pipe or double pipe?

As the name implies, these systems differ in the number main pipelines supplying coolant to radiators. In a single-pipe scheme, all battery connections are connected to one common pipeline, which is both supply and return. A striking example of such a system is the famous "Leningrad", shown below in the figure:

With the apparent ease of installation and savings in materials, a single-pipe system has one serious drawback. Since each battery discharges cooled water into a common line, the coolant comes to the next radiator with a lower temperature, and so on, until the end of the branch. Because of this, the very last heater may be barely warm. What does it mean?

The room still needs to be heated, which means that you will have to increase the heat transfer of the battery, that is, increase the number of sections. It turns out that we saved on pipes and fittings, but spent on additional sections. Add to this the difficulties with regulation in two-story houses and the impossibility of natural circulation.

The disadvantage of a two-pipe system is only that more materials are needed to assemble it, since in this case the supply and return manifolds are separated. That is, the coolant comes to all batteries through one pipe, and leaves through another. This scheme of the heating system of a private house has many advantages, and therefore is the most popular. This is a reason to opt for a two-pipe system.

Types of two-pipe systems

Currently, the following types of two-pipe schemes are used in private housing construction:

• with natural circulation;
• with forced circulation;
• collector system;
• scheme with a double-circuit boiler.

Each of the above systems has its own characteristics, advantages and disadvantages that determine its scope. Consider all the schemes in order and reveal their features.

Natural circulation system

The principle of its operation is based on the convective movement of water. The hot coolant leaving the boiler has a lower density and weight than the cooled water coming through the return line. The latter tends to sink down and displace the lighter heated coolant. Due to this, it happens natural circulation. For the normal operation of the system, several conditions must be met:

• due to the low velocity of the liquid, the diameters of the pipes must be increased to ensure the necessary flow of the coolant;
• the difference between the densities and masses of water with different temperatures small, so the heating circuit with natural circulation should be mounted with large slopes of horizontal sections;
• the pipeline network is under natural pressure, it is unacceptable to create excess pressure, otherwise the flow of fluid will stop. This means that the expansion tank can only be of an open type and must be installed above the entire system;
• to withstand all slopes, the boiler often has to be placed in a small depression.

What does such a heating distribution scheme give us in a two-story house, where compliance with all conditions requires careful calculations and leads to a large consumption of materials and installation complexity? The answer is simple: a gravitational circuit that functions in conjunction with conventional solid fuel or gas boiler, does water heating two-storey house independent of electricity. Sometimes it's very important factor, for example, in areas with unreliable power supply. This is the scope of gravity systems.

Forced circulation system

Here, the movement of the coolant through the pipeline network occurs due to the work circulation pump which creates excess pressure in it. The introduction of a pumping device into the circuit made it possible to achieve the following advantages:

• reduction of pipe diameters. The fluid flow rate has increased, and now a smaller flow area of ​​pipes can be used to ensure the required flow;
• improving work efficiency. If the forced circulation heating scheme is designed correctly, then high-temperature water will successfully reach both the nearest and the farthest radiators;
• pipes can be laid in the most convenient way, which plays a huge role in interior design issues. The lion's share of highways can be hidden using boxes or floor and wall structures;
• convenience and comfort in use. The fact is that forced circulation makes it possible to implement any projects to automate maintaining the climate in the house;
• economy in energy consumption. The conclusion follows from the previous paragraph, since automation allows you to heat the premises according to the daily schedule at a time when there are people there;
• the system is easily adjustable.

Note. In two-story houses where the old scheme with natural circulation is involved, you can always put a pump. This modernization will make it possible to realize, if not all, then the main advantages of the pressure system.

Installation of a circuit with artificial inducement is laborious, but relatively simple, it can be easily done by hand. Take at least an expansion tank of a membrane type, which does not need to be placed in the attic, and even control the water level, as with gravity. Its place is in the furnace room, near the boiler.

The most significant drawback of the circuit is its volatility. One has only to turn off the two-story house from the electricity, and after a while the heat in the rooms is gone. The ways to eliminate the disadvantage, although simple, are costly: the purchase and use of an electric generator or, at worst, an uninterruptible power supply.

As for the allegedly high cost of materials, we have already discussed this issue, speaking of a one-pipe system. Although it should be noted that the cost depends on the number of control valves and automation tools included in the heating project. In the budget version, the assembly of the circuit will cost a little more than a single-pipe one.

Collector heating system

This is one of the new trends in the field of heating private houses, which appeared relatively recently and originated from two-pipe pressure systems. Only in contrast to them, the collector heating system of a two-story house has many branches converging to one center - the distribution manifold. The circuit resembles a set of rays diverging in all directions, with a distributor inside, as shown in the figure:

As you can see beam system heating provides for a separate connection of each radiator to a collector directly connected to the boiler. In this case, the "beams" are completely hidden in the floor structure, and the distributor is built into the wall inside a special cabinet. Only the connections to the batteries remain in sight, and even a branch coming from the boiler.

It is unnecessary to convince someone that the collector heating scheme in a two-story dwelling is the most efficient of all. Each radiator is powered separately, they do not affect each other. Adjustment and automation can be implemented in any way. The rosy picture is spoiled by only one circumstance - the high cost. This fact is also well understood at one glance at the diagram. There is also a disadvantage that has been inherited - dependence on electricity.

Heating scheme with a double-circuit boiler

In fact, the heating scheme of a two-story house with a double-circuit boiler is no different from a conventional two-pipe system. The problem is somewhat far-fetched and its solution does not depend on heating networks in any way. The crux of the matter is that the double-circuit boiler is disconnected from the system during water heating and is exclusively engaged in hot water supply. If it takes a long time, then the building starts to cool down and it becomes cool inside.

A similar situation is a consequence of an incorrect selection of the boiler power, the installation of heating has nothing to do with it. The power of the heat generator should be determined taking into account the heating of water at the DHW. If this has not been done and the boiler has already been installed, then there is only one way out - to reduce the temperature of water heating and use it sparingly.

What is the best heating system for a two-story house?

The answer to the question depends on individual conditions and wishes. If you want not to depend on electricity, you will have to make a gravity system with all its shortcomings. When there is a desire and opportunity to build an efficient and economical scheme, then a system with a collector connection is at your service.

In practice, heating distribution in two-story houses is most often two-pipe with forced circulation. In terms of cost and efficiency, this is the best solution, it allows you to realize a lot of opportunities and economically heat your home, incurring costs of medium size. Yes and for self assembly this scheme is quite convenient.

The heating system of a one-story building does not raise any special questions even among inexperienced, little versed people in this industry. Most imagine how it can be equipped, and therefore only clarify some details that are incomprehensible to themselves. But the heating scheme of a 2-storey private house is more difficult not only to implement, but also simply to understand.

If you have a two-story own house or a country cottage, you want to equip the heating system with your own hands, but do not know where to start, our article will help you solve all the problems that arise.

Variety of options

The main feature is that it is necessary to ensure the rise of the coolant to the second floor, that is, to the height specified by the building project. How to solve this issue - we'll talk in this section.

To begin with, let's decide what kind of equipment and components are required:

• boiler;
• pipes and batteries;
• stop valves;
• temperature controllers, other additional measuring devices, control sensors.

The operation of the entire system directly depends on the quality of the components used - so do not skimp on them! Modern, reliable equipment will not only provide you with the microclimate you need, but will also help you avoid emergency situations.

Now let's move on to a variety of schemes used in the arrangement of a heat supply system in two-story buildings.

Proven types of heating schemes

There are several time-tested and many people designs:

• with bottom wiring;
• with top wiring;
• 1-pipe system;
• 2-pipe system;
• depending on the type of circulation used - forced or natural;
• depending on the position of the risers - traditional, vertical or horizontal (very rare)

Most often there is a scheme that provides for the forced movement of the coolant. It is more efficient, allows you to ensure uniform heating of the entire house. But in addition, you will need to install a special pressure pump and an expansion tank. The boiler can be virtually anything - both gas and solid fuel, and so on.

Which scheme is better?

Most often, it is customary to use a two-pipe scheme, which is characterized by:

• universality;
• reliability;
• economy.

For example, when using a single-pipe version, it will not be possible to ensure the adjustment of the heating level of individual batteries, because in this case all radiators used are connected in series and when the coolant supply to one of them is cut off, all subsequent ones will also receive less heat.

In a two-pipe scheme, each battery involves connecting two separate pipes:

• for supplying the coolant;
• to take him away.

This also allows for the installation of a control valve on each battery, which will make it possible to control the temperature in any room of your house, and not be tied to the entire building.

The collector type definitely deserves attention - it is more expensive in its arrangement, and therefore not so popular, but it has its own positive traits. Among them is the hidden location of all pipes, which has a positive effect on the interior. The design features are as follows:

• the boiler is placed on the first floor;
• expansion tank - on the top;
• pipes run under the floor, under the ceiling or under the window sills.

Also, a valve can be installed on each battery to control the temperature level in individual rooms.

From the above description, an intermediate conclusion can be drawn - the best option would be to install either a two-pipe or a collector circuit. The first is cheaper, the second is more expensive, but wins from an aesthetic point of view!

Choosing pipelines

Equipment selection - important point. Which boiler to use is an individual matter, it all depends on your preferences and financial capabilities. If you are not afraid of heating bills, you can leave gas, and if you want to save money, choose solid fuel or the so-called hybrid, which can run on different types fuels (gas-electricity, solid fuel-electricity, electricity-liquid fuel, etc.). You will learn more about hybrid boilers in the article.

A hybrid boiler is an order of magnitude more expensive than a mono-fuel boiler, but in the end it is a real opportunity to always be in a warm house and save on one of the fuels.

If the question of choosing a boiler is individual and we cannot give specific advice, then everything is wrong with pipes for wiring. We are ready to help you with this. So, when choosing pipes, it is important to remember that not only the reliability and durability of the system, but also the rate of heating the room depends on their material.

If you want to reach high level heat dissipation recommended copper pipes, which, by the way, perfectly resist the appearance of corrosion, are able to withstand even high pressure;

A budget option that is common today is metal-plastic models, which, however, are also characterized by high quality and heat dissipation.

Don't Forget Availability expansion tank- this is an obligatory element of the scheme, contributing to the safety of the heating system!

You also need to remember that various deposits are not collected inside the metal-plastic models, “congestion” is not formed. Even after a long period of time, your system will work as efficiently as possible!

All other types of pipes are recognized as inefficient, quickly losing their reliability and are not able to provide high-quality space heating for many years.

What else needs to be remembered?

Be sure to take into account all the little things and details. After all, it is necessary to create not only an efficient, but also a durable heating system that will work for at least 25-50 years without requiring overhaul and replacements. It is better to “invest” once, spend a large amount, but enjoy the warmth in the house for the rest of your life!

Moreover, a properly selected scheme, a responsibly made heating system will allow:

• create an ideal microclimate in the house even in severe frosts;
• qualitatively warm up each separate room;
• control the temperature in each room;
• reduce the cost of purchasing fuel, energy carriers, because their consumption will be less.

And in general, the absence of any problems in the functioning of the heating system will allow you to avoid unnecessary, unplanned costs.

Radiator heating scheme on video

We have given you the main, most popular options for creating heating in a two-story private house. These methods will also apply to country cottages. The drawings presented in the article will allow you to better understand the principles of arranging the system - we are sure that our information will be useful to you and will allow you to avoid unnecessary expenses.

The choice of heating scheme for a two-story house depends on its area and layout. The most familiar and widespread scheme for summer cottages and country houses there is still a heating system with natural circulation of the coolant, not much different from the heating scheme of one-story houses.

The only feature of the natural circulation heating distribution scheme in a two-story house is the choice of a place to install an expansion tank. There is no need to take it to the attic and you can limit yourself to location anywhere on the second floor (of course, at the highest point of the room), providing the ability to discharge the coolant.

With this method of connecting heating devices, the coolant enters them from above (upper wiring), which ensures uniform heating of radiators and heated rooms. To ensure the directed movement of the heat carrier, the pipes must be laid with a slope of 3-5 degrees, bearing in mind that the diameter of the return pipeline should increase as it approaches the boiler.

The supply pipeline can be laid under the ceiling or under the window sills. Examples of connecting radiators are shown in Figure 1.

Among the advantages of the heating scheme of a two-story house with natural circulation are:

• Independence from the power supply
• Reliability
• Ease of operation
• Noiseless operation of the system

Unfortunately, there are many more disadvantages in a natural circulation heating system than advantages:

• The complexity of installation and the need to lay pipes with a mandatory slope
• Small heated area: the system simply does not have enough pressure to heat a two-story house with an area of ​​​​more than 130 m2
• Low efficiency
• Large temperature difference between supply and return, which adversely affects the operation of the boiler
• The presence of oxygen in the coolant and, as a result, internal corrosion of the system
• The need to monitor the level of constantly evaporating coolant and add it. As a result, scale forms on the pipes.
• For the same reason, you can not use antifreeze
• High material consumption of the system

It is much more efficient to use heating systems with forced circulation of the coolant in a two-story house. In this case, it is easiest to implement the following schemes:

• Single pipe
• Two-pipe
• Collector

You can do them yourself

One-pipe heating scheme for a two-story house

With a single-pipe scheme for connecting heating devices, the movement of the coolant is divided into two branches, one of which goes to the first floor, and the second to the second floor. On each floor, shut-off valves are installed at the inlet of the heating pipe, which allows heating only half of the premises.

After passing through the heating devices, the pipes with the coolant are again combined into one going to the boiler. The connection of radiators on each floor is the same as for one-story buildings.

To regulate the level of heating of radiators and to balance the system, shut-off valves are installed at the inlet of each heater. Shut-off valves are also installed at the outlet of the radiator, designed to turn it off in case of replacement or repair. With this connection, the replacement of heating devices can be performed without stopping the entire system and draining the water. Also, a valve for air release is installed on each radiator in its upper part.

The installation of radiators is carried out with a bypass line, which greatly increases the uniformity of heating the room. It is possible to install heaters without a bypass line, but in this case it is necessary to install heaters of various thermal power in the house, taking into account the loss of coolant cooling: the farther from the boiler, the more sections the radiator should have. If you do not follow this rule, then in some rooms it will be hot, while in others, on the contrary, it will be cold.

The heating scheme of a two-story house can be without shut-off valves, or rather, with a smaller number of them, but at the same time its maneuverability is greatly reduced. In this case, it is no longer necessary to talk about separate heating of the first and second floors.

Advantages and disadvantages of a single-pipe heating system

• Single pipe heating system is relatively easy to install
• Its use ensures efficient heat dissipation
• The single-pipe heating system of a two-story house allows you to save on materials.

The disadvantages of this type of heating system include the uneven distribution of heat over the heating devices, as well as the need to balance the system.

All these shortcomings are deprived of a two-pipe heating system of a two-story house with forced circulation of the coolant.

Heating scheme with forced circulation of a two-story house

The two-pipe forced circulation heating system of a two-story house ensures even heat distribution and is more efficient system, not in vain it is often compared with the human circulatory system. In it, the heated coolant is supplied to each heater separately through a branch from a common supply pipe. A branch is also provided for the return pipeline from each radiator.

Radiators are installed with air vents and shut-off valves on the supply pipe, which allows you to change the degree of heating of the heater. For safety reasons and to avoid excessive pressure in the heater, no shut-off valves are installed on the return pipe from the radiator. The supply pipe can be laid under the ceiling or under the window sill.

The only drawback of a two-pipe heating system is its high material consumption: pipes are needed in double quantity for supply and return. In addition, pipes are difficult to decorate, and it is not always possible to hide them. All these shortcomings are deprived of a collector heating circuit.

Collector scheme for heating a two-story house

The collector circuit can be used with equal success for heating both a one-story and two-story house. It works only with the forced movement of the coolant, which is preliminarily supplied to the collector. In this case, each heating device is separately connected to the collector through a shut-off valve.

This connection method allows you to mount and dismantle heaters on a working system, without stopping it and draining the coolant.

• The system is easy to manage. Each circuit is independent and can be connected to a separate automatic control system with a separate circulation pump.
• Can be connected to underfloor heating
• You can hide the pipes in the raised floor by placing the collector in a separate cabinet
• The heating system is simply mounted and can be done "with your own hands"

What to give preference

Any of the above heating schemes for a two-story house has been tested in practice and has repeatedly proven its effectiveness. There is no fundamental difference between them. It is much easier to implement a collector heating circuit in practice.

• I have a 2 storey house. On the ground floor there is heating without a pump. Second floor without heating. Is it possible to connect the second floor to the existing heating through a pump, and leave the first floor without a pump? All heating from one boiler. If possible, how?
• Good afternoon! Tell me please! My husband and I built the house ourselves without involving other persons. But we can’t decide on heating. The house on the 2nd floor has a boiler room at the level of the 1st floor.
• Good day. Hanging boiler, two pipe system polypropylene 25 mm. Built an attic. On the second floor, the builders launched a metal-plastic pipe 20 under the floor. THANKS.

The question of how to properly make heating in a two-story house is quite complicated, and installing a boiler and do-it-yourself piping seems problematic, especially if the system is unfamiliar to you. However, if you prepare a heating project, the system carried out in a two-story house may be too tough for you.

In this case, there may be a two-pipe or one-pipe heating system of a two-story house, forced circulation or natural circulation, a double-circuit boiler or a single-circuit one. In the photos and videos that are posted on our website, it will be possible to distinguish in more detail the features that the system has, each heating wiring diagram has its own advantages.

Types of heating systems

You can equip a two-story house and lay pipes yourself, but best solution- if the system is assembled by a pro. Then the heating of a 2-storey house will be the most effective.

The heating scheme of a 2-storey private house differs in many characteristics. For example, heating may include one or two pipes for supplying coolant, regardless of whether it is forced circulation or natural.

In the first case, the heating of a two-story private house is carried out if the pipes are of small length. The one-pipe system assumes that, having completed the heating of a 2-storey building, the water from the radiators does not go into the boiler, but enters the hot pipes and mixes with it. As a result, the circulation of chilled water begins, and it becomes difficult to efficiently heat a 2-storey house in remote sections of the pipe.

Therefore, heating a two-story house in the version with a single-pipe system is not recommended to be developed independently, and even more so to assemble the pipes with your own hands. The exception is Leningradka - this is an easy-to-implement one-pipe heating system in a two-story house, its scheme is one of the best in simplicity. Leningradka allows you to make heating a two-story house without much effort.

The two-pipe heating system of a two-story house has proven itself well - it has only forced circulation, natural is not provided. The system has two pipes, so that the liquid on its way to the boiler, whether it is a double-circuit boiler or not, does not enter the pipes with cold water, as a single-pipe heating system assumes. A more thoughtful two-pipe wiring avoids heat losses, so that the heating of a 2-storey house becomes efficient. Moreover, a two-pipe heating system is perfect in cases where a 2-storey house has a significant area, and the pipes are long.

The scheme and system may provide for the circulation of the coolant to be natural and forced. This best options if heating is planned to be economical. Natural circulation, when heating a 2-storey house is needed, occurs due to the heating and cooling of water inside the pipe. The heating system with natural circulation is relatively cheap. An alternative is forced circulation, when in a 2-story private house heating is carried out with an electric pump.

The boiler itself in a two-story house can be double-circuit and single-circuit. A double-circuit boiler has proven itself better, because in a 2-storey house through pipes it will be possible to carry out not only heating, but also hot water.

For this, additional pipes are installed, which the water supply system has, heating - separately. The scheme for them in a two-story house is developed separately with their own hands or with the involvement of a specialist. But if you need heating for a 2-storey private house, a double-circuit boiler is not always suitable. With the help of videos and photos, it will be possible to evaluate which system is better and choose the right heating.

Choosing a heating system

When designing heating, the scheme and system must be thought out based on the area that a 2-storey house has. It is important that the system distributes heating to the entire 2-storey private house through the pipes completely. If the pipe laying scheme is developed independently, it is still better to show the heating of a 2-storey house to a specialist.

When it is decided to assemble the heating of a two-story house with your own hands, natural circulation will be quite complicated. Therefore, most often, the scheme provides for the installation of pumps, due to which not natural, but forced circulation of the coolant through the pipes is ensured. Then that two-pipe, that one-pipe heating system will show the best results. How the pipe is laid out, you can look at the photo and video.

The simplest project is the Leningrad heating scheme. This is a one-pipe heating system of a two-story house, where there is natural circulation. The system can be assembled by hand, which is the best option for those who want to equip a 2-storey private house with the lowest pipe and radiator costs.

The most difficult to implement is the collector heating system of a two-story house. This project is designed to carry out heating of spacious rooms. The collector circuit cannot be assembled by hand, even if you use video and photos.

Calculation of the heating system

When making the calculations yourself, you need to take into account such factors as the wiring and pipe length, the boiler used, the pipe laying scheme. Of course, heating a 2-storey private house will cost more than a system in a one-story private house. Also consider that natural circulation is cheaper than artificial circulation.

With video you can get best advice masters how to equip a two-story house, including learning the calculation formulas. In addition, a heating project for a two-story house can be developed by a professional - it will be more reasonable, because then the pipe wiring to a 2-story private house will be organized correctly.

Financial expenses

When calculating how much a self-installed system will cost, specify whether the boiler will be double-circuit or single-circuit. Add to its price the cost of the pipe and fixtures. Ideally, heating a 2-storey building should be inexpensive. But you should not save too much, otherwise the system will cool down a 2-storey private house. However, a double-circuit boiler can be replaced with a single-circuit one, heating will not deteriorate significantly.

The Leningrad heating scheme is quite cheap. This natural circulation heating system of a two-story house is also efficient. Leningradka does not require long pipes; the circuit of this heating system for a two-story private house is simple to implement. Simple wiring and system allow you to do everything yourself.

A two-pipe heating system is more expensive, especially in a two-story house. And the most expensive is the collector heating system of a two-story house with forced circulation. The wiring of its pipe itself can only be done with great effort, so heating in a two-story house should be carried out by specialists.

Find out for yourself how much you plan to spend on heating, how “gluttonous” the system is. Sometimes the boiler is the reason why heating a 2-storey private house becomes too expensive. The system can work on various types fuel. When installing the boiler in a private house, electrical wiring may be required. If there is a double-circuit gas boiler, you need a pipe for gas supply.

Pipe selection

When choosing pipes to equip the heating of a 2-storey private house, pay attention to their material. Pipes made of steel or polypropylene are installed in a private house. Regardless of the pipe material, the system, scheme and wiring for which heating is carried out in a 2-storey private house does not change.

The key factor is only the diameter of the pipe - it depends on whether forced circulation is needed or natural circulation will still be possible. The diameter of each pipe to a private house is calculated based on which system is in a two-story house, and at what speed the coolant should move. In addition, you need to consider what the system, project, scheme and wiring will be like - single-pipe or two-pipe, Leningrad or collector.

One-pipe and two-pipe heating system: diagram with video

To find out what scheme is needed in a private house, we recommend that you familiarize yourself with the photo and video materials. They can be found on our website. Most of the photos were taken in good quality, pipes in a two-story house are perfectly distinguishable. Also in the photo you can see the fasteners, with the help of which the pipes in a 2-storey private house are interconnected. If you need wiring, its diagram is also available on the site. Using the photo and other materials from our website, wiring to a private house can be done by hand.

Especially if a single-pipe heating system in a private house is Leningradka. It can be carried out in any two-story house of a small area. A double-circuit boiler is not needed, and the heating project allows you to place a small number of radiators in a private house, and the pipe length should not be too long. Otherwise, self-assembled heating in a private house will turn out to be inefficient, a 2-storey private house will begin to cool down.

In a two-story house, not only a one-pipe, but also a two-pipe heating system can be carried out. Comparing which one is better - one-pipe or two-pipe - it is worth noting that they have nuances of application. For example, a two-pipe heating scheme is suitable if a private house is spacious. The two-pipe system does not mix cold and hot water. A single-pipe scheme does not have such an opportunity, this project becomes less effective, because cold water on the way to the boiler, it mixes with the heated one - this is the system.

If you need an efficient heating scheme for a two-story house, the best options are quite complex, such as a collector system. However, even in this case, the photo will be useful - the collector circuit in the house can be installed with your own hands, if there are samples. Sometimes the collector system is considered as a separate variety. Using the photo and the best tips from the masters, it will be possible to install the heating in the house in the best way.

Heating a two-story house with a double-circuit boiler: scheme

When preparing a project for a private house, pay attention to what the system is. If a double-circuit boiler is planned, its pipe layout has its own differences. For example, a double-circuit boiler allows you to connect not only pipes to heat a 2-story house, but also makes it possible to connect water pipes to a two-story house.

A double-circuit boiler in a private house is characterized by a long service life. The heating scheme of a two-story house with a double-circuit boiler is two-pipe, it has such advantages as the possibility of flexible regulation. If the system fails, the boiler can be disconnected from the pipe itself.

Heating system with natural and forced circulation

Forced circulation and natural circulation differ in that in the first case, water enters a single-circuit or double-circuit boiler and leaves it through the pipes where the pump is installed, and in the second, the heating of a 2-storey house is designed so that the system itself pumps the coolant through the pipes into House.

As a rule, the natural current scheme is used when the system is single-pipe, and when it is two-pipe, heating will not do without a pump. However, if the system is not two-pipe, the heating of a 2-storey building can still be carried out using a pump.

You can get acquainted with how the forced circulation of the heating system of a two-story private house is organized using a photo. Regardless of whether the system is two-pipe or one-pipe, the choice of whether forced circulation or natural circulation is needed should be based on the opinion of a professional. It is necessary to decide whether there should be natural or forced circulation, even at the stage when the project is being prepared, and the system, pipe wiring and heating scheme are only in the plans.

Collector heating system

Considering the best options, the collector heating system in a private house attracts attention. Her distinguishing feature- pipes lead to collectors, for which the collector system got its name. Such wiring in a private house is universal. It allows you to mount a double-circuit boiler and pipes to it in the most convenient way. It should be noted that the collector system is not a single-pipe system and not a two-pipe system, sometimes it is isolated.

The collector system has one drawback - the pipes to the house are too elongated. The advantage that the collector system has is the ability to make the heating of a 2-storey house according to the "warm floor" principle. You can find out how to equip a private house with it on our website, including a photo showing the collector system.

Pipe routing options

It is believed that laying a pipe in a private house is a difficult task, however, by looking at the photo, you can make sure that both a single-pipe, two-pipe, and a collector system are nothing complicated. It will be possible to assemble them with your own hands, if used best pipes without defects. If desired, you can even connect a double-circuit boiler yourself.

If planned gas heating, the scheme, including the location of the gas supply pipe, must be agreed with the competent authorities. Accordingly, wiring to the house is carried out only after the system is approved, whether it is single-pipe, two-pipe or manifold.

Do-it-yourself heating installation in a private house

You can independently install a single-circuit or double-circuit boiler in the room, in the same way it is allowed to mount pipes. But there is a condition: the wiring must be carefully thought out, and the performer must be experienced enough. It will be difficult if natural circulation is provided.

The best options are when the system, including pipes, is installed in a private house by specialists. Regardless of whether the circulation is natural or artificial, the wiring will be correct, and you will also receive a guarantee of quality. It does not matter which system is a collector or another type. The masters will surely cope with the task, and the heating will work efficiently.

If you want to make heating without professional support, use the photo from this page - the system for a private house is described in detail on our website. However, photos alone will not help you, and in order to assemble heating, you still have to seek advice, for example, in order to correctly calculate the diameter of the pipe.
