Water heating private house with his own hands: schemes and tips

district heating inaccessibility makes us think about mounting autonomous system. With it you can create a comfortable environment inside the building at any time of the year. Most choose water heating private houses. His hands schemes most complex contours can be mounted to almost everyone. We offer to meet with distinctive features and nuances of water heating installation work.

Advantages and disadvantages of water heating systems

characterized a number of advantages for water heating:

Disadvantages water heating include:

Heat transfer fluid and its properties

As the coolant water is widely used. This is facilitated by its main properties. It can not have a negative impact on a person even in case of damage of the heating circuit. It has a high level of heat transfer. The viscosity of water makes it a good option for any modern water heating.

The disadvantages of water should include:

• freezing at zero temperature;
• increase in volume when changing the state of aggregation, which may cause a rupture of the pipeline;
• salt content, which lead to the appearance of the precipitate on the inner surface.

Attention! To prevent deposits on the inner surface, only the distilled water must be poured into the heating circuit.

Instead of water, are often used antifreeze. Such materials are not afraid of low temperatures, however, can not always be used in traditional water heating system. They are toxic and can have a negative impact on human health in the depressurization system.

The rules and requirements for autonomous heating

to the heating system requirements are described in SNIP 2.04.05-91. limits are designed to create a comfortable microclimate in this document. Some of the recommendations given in SNIP 31-02, regulates the right of construction of single-family homes.

Separately establishes requirements for used coolant. Its temperature should be between + 60 ÷ 80 ° C. The maximum heating is limited to + 90 ° C. Thus the outer surface of the heating elements to which access is not particularly limited, should not be heated above + 70 ° C.

When deciding how to make a private home heating, it is worth paying attention to possible ways of heating installation pipeline. Preference may be given to:

• Open. The pipeline is laid on the building structures. Used for fixing clamps and clips. Are used metal pipes. The choice in favor of polymer products is done only when possible to protect them from mechanical and / or thermal effects;

• Hidden. Laying is performed in the water circuit specially prepared cutting grooves and channels, which are hidden behind the various decorative elements. Relevant to the buildings, which are planned to operate for at least 20 years. In this case, the service life of the pipe must be greater than 40 years.

Attention! Open method of laying a priority.

Features a water heating system

This system was a direct continuation of stove heating. It allows you to simultaneously heat several rooms, while the traditional oven with this task can not cope. For this installed heaters, which arrangement worked out for each particular house individually in each room.

The heat transfer fluid heated in the boiler to a desired temperature is supplied to the conduit. Moving through the pipes, he begins to give its heat to the radiators, as which can act radiators or circuit "Warm floor". Heating devices, in turn, transfer the heat to the surrounding space. The cooled coolant is returned back to the boiler is heated to a predetermined temperature, and the cycle is repeated. Due to the continuous movement of the coolant of struggling to maintain the temperature in a private house at a comfortable level.

Basic elements of a water heating system

Learning how to make a heating system in a private home is to get acquainted with the basic elements. They can have various design and made of different materials. From the choices made will depend on the period of service water heating and ease of use.

Boiler

This member supports the water heating efficiency. It produces heat to heat water to the desired temperature. Manufacturers offer boilers running on:

1. electricity. Optimal in terms of safe operation. Such equipment does not impose high requirements for the installation site. It does not emit combustion products. However, high operating costs and dependence on energy makes to consider other options;
2. Gaza. A popular option, if the pipeline passes near a private house. Low operating costs and a fairly high efficiency make this equipment quite popular. Run the installation gas boiler with his own hands is not possible;
3. Liquid fuel. Similar in design to gas counterpartBut it is equipped with a different type of burner. Installed in a separate room. Due to the large amount of combustion products requires regular cleaning;
4. solid fuel. The best option for the private sector. Installation can be done by hand. During operation it is necessary to lay constantly fuel into the furnace and clean combustion products.

Attention! Manufacturers offer a combination boilers that can run on different fuels.

Choosing suitable model, it should focus not only on the type of fuel used, but also on power equipment. On average, 1 kWh is enough to heat 10 squares in a private house, located in the southern regions. In the middle band component to rise up to 1.5 kW, and in the north - to 2.0. To the resulting value experts recommend to add another 20 ÷ 30%. handy calculator has been designed to facilitate the settlement of our team.

tubes

For heating circuit used articles made of different materials, each of which has its own characteristics. Preference can be given to the pipes:

• steel. Such products are still relatively recently enjoyed the greatest popularity. However, in the construction of private homes in the present they are used less often. The reason lies in the tendency to corrosion of steel surfaces;

Tip! Having decided to give preference to steel pipes, galvanized items should buy or stainless steel.

• copper. The conduit of copper capable of resisting to high temperatures and pressure. It is characterized by long life, but the high cost elements of significant copper limits their use;

• polymer. Products made of plastic, which is based on aluminum, covered by a plastic layer, or polypropyleneAdditionally reinforced aluminum, have a number of advantages. They have no fear of corrosion, have sufficient strength to prevent the appearance of a precipitate on the inner surface. Installation of water heating does not require significant financial investments, as it can be done with their own hands without the use of special equipment.

Attention! Due to the high thermal expansion coefficient of polymers it is likely damage to the pipe during the freezing circuit.

radiators

The efficiency of heating water largely depends on the characteristics set radiators. Manufacturers offer a battery made of:

• become. These products have affordable price. However, the tendency to corrosion significantly reduces the possible duration of operation;
• aluminum. Products are highly resistant to corrosion processes at low resistance to pressure drops. Given that the pressure in private homes, as a rule, stable aluminum radiators are able to last for a long time;
• steel and aluminum. Bimetallic radiators have the advantages typical of products made from either aluminum, enjoy steel;
• cast iron. Large battery weight places increased demands on fasteners used.

Water pumps for heating private houses

Used to provide continuous circulation pump of the heating circuit. From its characteristics depend largely stable heating operation. Manufacturers offer water pumps for heating private houses different productivity with different the pressure.

The first parameter can be calculated as follows: power system divided by the coolant temperature difference between inlet and outlet and the water component of the heat capacity. The pressure is selected so as to provide normal current at each point of the coolant. Especially for our readers, we have prepared a handy calculator to calculate the performance and the circulation pump pressure.

Expansion tank and feeding system

Included in the closed heating system. To compensate for the difference in coolant volume during heating and cooling. Expansion tank It consists of two parts, a water and air. The pressure in the latter is adjusted so as to ensure hydrostatic equilibrium with the air filling part to a certain level.

As the hot water filling the chamber pressure rises, and liquid begins to push the membrane, increasing the pressure in the air chamber. After the coolant has cooled, the excess pressure pushes the liquid back. There are different types and scope. Below, you can use the handy calculator to determine the required volume of the expansion tank

thermal circuit

Designed for transmission, distribution and return of heating water in the boiler. It needs a careful selection of the pipe material, since excessive roughness may cause inhibition of the transported fluid. Depending on the flow resistance selection is made in favor of the circuit with the natural or forced circulation.

The choice of heating devices

When choosing a boiler for heating water should focus on its capacity, particularly mounting the geometric parameters and the type of fuel used. Considered to be the most practical gas modelsWhich can be replaced if necessary is solid or electric analog. The costs of operation of the boiler, solid-fuel, much lower than the electric model. The last will be the best option for small private homes.

When choosing a heating device should take into account how to install a boiler in a private home. No separate space considerably narrows the list of suitable models.

Types of water heating systems

Before you start to deal with how to carry out heating in a private house, it is necessary to get acquainted with existing types of systems. Each of them has its own distinctive features, identifying possible areas of use and the order of installation.

Water system "warm floor"

Most often used in conjunction with the heating system of another type. Installation is rather complicated and requires careful compliance requirements. The main advantage underfloor heating - a large heating area. Due to the fact that the floor is a large heat sink, it is possible to provide heat transfer in the optimal mode. The heated air rises from the bottom upwards, filling the space. In the circuit water temperature drops to + 55ºC.

The disadvantages of water system "Warm floor" It should include the need for installation work at the construction stage of a private house. In the finished structure to implement the project is difficult. After laying the ceiling height is reduced pipeline.

Baseboard heating system

Heating water heating elements have a shape resembling outwardly titled analogue building. Inside heater arranged elements including copper tube. Durable hollow metal box provides a good heat sink.

The heating elements are mounted on the perimeter of the room, so that is possible to maintain the temperature at a given level. With the passage of coolant occurs sequential heating copper tubes, metal boxes, the air, walls. As a result, indoor air is warming, not only because of the heat baseboardsBut the walls along which they are mounted.

The most rational is the water heating installation in areas directly bordering the street. This is a suitable option for the balcony, veranda or terrace. The advantages of baseboard system include:

• forming a comfortable environment without active circulation of air;
• insulation of places where mold often appears;
• ease of installation work;
• choice of a suitable design elements;
• availability.

The disadvantages include limited (up to 15 meters) loop length. Often mounted in one room 2 ÷ 3 circuit. Another negative aspect is the inability to install furniture along the horizontal elements, as this will reduce the efficiency of water heating.

radiator

The most common variant. Heat transfer is carried out from heated to a certain temperature radiator batteries installed in each room. Radiator type is preferred when a water heating device, not only in homes but also public buildings. Competent selection of the heating circuit elements allows good use of interior space and create a comfortable environment in every room.

The popularity is due to the simplicity of the installation work. Installation elements can be made with your own hands.

heating system one-storey house with natural circulation of coolant

Water heating with natural circulation is important for heating private house a small quadrature. Movement of the coolant heating circuit is provided by the action of gravitational forces and the laws of physics, providing the rise of water through the pipe.

Warmed up and setpoint water, leave the boiler starts up the pipeline and then descends to the distal radiator. Thereafter, the taps of the coolant begins to flow into the other radiators. Cooled radiator returns to the return pipe and down to the boiler.

When assembling the heating system with natural circulation one-story house you must create a sufficient slope to facilitate the flow of coolant through the pipeline. The length of the horizontal portion 30 meters is limited.

Installation of heating systems without pump differs accessibility, as it implies the rejection of the use of additional equipment. However, due to limitations of the horizontal portion and the need to mount many larger diameter pipes prefers heating with forced circulation.

Systems with forced circulation of coolant

This scheme assumes that a special pumpProviding forced circulation of coolant through the pipeline. As a result, it is possible to:

• heating private house more quadrature, including several floors;
• forming the contour with multiple bends;
• installation of pipes with small transverse dimensions.

Preferred is a closed circuit in which the amount of oxygen carried by the coolant being drastically reduced, which increases service life of the mounted loop. Expansion tank can be placed anywhere. The disadvantages include the volatility and the high cost of installation work.

heating circuit in a private house with his own hands

How effective is heating, depending on the characteristics of the mounted circuit. heating scheme in a private house with his own hands can be realized in different ways. Please find with the options to choose the best option.

Driving pipe system of a private house with his own hands heating

Single-pipe scheme assumes that the heat transfer fluid from the boiler starts to move in a single line, and then it is returned back. Radiators are connected to the line at both ends. Properly mounted one-pipe heating system of a private house with his own hands works as follows:

• the coolant is heated to 75 ÷ 85 ° C and begins to move through the pipeline. After reaching the first radiator, part of hot water fills the battery, and the remainder continues to move pipes;
• passing on the heat radiator and delivered into the surrounding space, water is mixed with the coolant, reducing its temperature a few degrees;
• the next radiator situation repeats. As a result, water enters the battery last significantly cooled down, which reduces the amount of heat given.

Scheme and the procedure for single-pipe heating installation involves building up the radiator section, starting from the second of the boiler to provide uniform heating of all rooms of private homes. Water heating is working quite effectively if it contains no more than 5 batteries. The high-rise structure is often installed several risers. This presupposes a vertical circuit operating stably 3 ÷ 4 cells.

Attention! Single-pipe circuit can be both natural and forced circulation.

Scheme two-pipe heating system

Stable and reliable option that supplies to radiators located in different rooms, coolant, preheated to the same temperature. The heated water moves in one tube, and cooled down - back on another.

Depending on the wiring circuit may be two-pipe:

1. deadlock. Coolant fed via the respective threads, fills all radiators, and the reverse - returns. Balancing ensures uniform heating of the batteries;
2. Passing. Loop heating circuit holiday home. The hands performing installation must ensure that the coolant for the primary and feedback branches moving in one direction. Suitable sufficiently broaching circuit;
3. collector. A suitable option for a large private home. For powering each radiator uses a separate two-pipe branch joins the Manifold.
