Heating private homes
High comfort level and comfort in a country houseduring the cold season can be achieved thanks to the quality of the heating system in it. Today, the most popular are fireplaces that allow to heat the space around them. But their presence allows to live in a country house in the warm season, but with the onset of cold weather is necessary to return to a city apartment. Many owners of country houses refuse heating system because of the high cost of the work, but to make heating private houses with their own hands is able to anyone who knows how to handle the tool.

You need to create a private home heatingto develop a project of the heating system circuit. To do this is to immediately determine what the heating system will be installed in the house: water, steam, air or electric. During the design phase of the project is necessary to make the system required power calculations. You will also need a diagram drawn by heating a detached house showing all the elements of the system.
private home heating system depends largelyby preference, financial capacity owners and feasibility of its installation in the house. Among the existing types of heating systems should allocate water, steam and electricity. Each of these systems has its advantages and disadvantages. To create a fully autonomous heating private houses - water, steam or electric, required materials and space heaters for each type of heating separately, as well as specialized fuel storage.
Water heating system
This heating system is most common. Water heating in a private house on its operational quality is the most reliable and easy. The main elements of the water heating system is cauldron expansion tank, A network of pipes, radiators. As additional equipment for this system using a circulation pump, thermostat, safety valves and air vent.
The fuel for this heating system can beuse almost any, as long as the boiler was working on this fuel. For water heating systems typically use pipe made of steel, galvanized, stainless steel, copper or plastic. The selected material will depend pipe reliability and durability of the system.
Material for pipeline
- Steel is subject to severe corrosion, but it is cheapand affordable. Installation of steel pipes is carried out by welding them. galvanized steel pipes is recommended to connect a threaded manner. Of course, you can walk by welding, but then the connection will rust.
- Pipes made of stainless steel are among the most durable, but their cost is high. Joining pipes made of stainless steel can be threaded manner.
- Copper pipes are among the most durable, reliable and expensive. For their connections using solder silver-solder.
- Plastic pipes are cheap and widely accessible. Connect can be stamped using threaded connections or soldering. The disadvantage of plastic pipes is their poor resistance to temperature extremes.
Two circuit or one?
Water heating system in a private home can be doneSingle and dual-circuit. Their main difference is that the dual system is used for space heating and hot water for domestic use, and single-circuit - only for one of these purposes. Quite often in the house lay two single-circuit system - one for heating and one - for water heating. The aim is to heat water for domestic use during the warmer months. With this approach, it should be noted that the heating of domestic water uses only 25% of the power boiler.
The preferred type of wiring
Pipework in a private home can be done indifferent versions: single-tube, double pipe, the collector. In private homes do recommend double-tube wiring, as it allows better control of temperature and easier to operate.
Important! Installation of radiators made under the windows of the house. Their size must completely cover the window opening, so if you can not install a large radiator, radiator, two standard sizes can be supplied.
The calculation of the private house for heating waterthe system proceeds as follows. First, we summarize the number of radiators to be installed. Then multiply the number on their performance and get the necessary power to the boiler. Based on these data, we choose the boiler.
Important! For convenience, the required boiler output selection, you can use the table above. It identifies the standard requirements for the boiler output depending on the area of the house.
Steam heating: the pros and cons
This heating system in private homes are rarely used. But the central heating in the private house has a number of significant advantages.
- Firstly, the loss of heat in the radiator practically no.
- Secondly, the steam has a heat-retaining properties, which allows the use of smaller diameter pipe.
- Thirdly, the entire steam system warms up quickly thanks to its low inertia.
Unfortunately, there are two significant disadvantages of this system. The first - a short life, and the second - a very high temperature, you can get burned from touching the radiator or pipe.
As for the water heating system uses one-pipe and two-pipe heating system.
Depending on the vapor pressure of the system can be of low pressure and high pressure. By type, they are open and closed, the difference in the condensate return mode.
Installation of water and steam heating systems
If from the outset in the building heatingit was planned to produce from the stove or fireplace, that during the construction phase should establish a chimney with built-in coil or water heaters cover. For these elements will be built to connect the heating system. Stove or fireplace, you can leave a safety net and parallel to install a gas or electric boiler. To directly prepare the boiler room - the boiler room. Lay the place of installation of refractory material, as well as the walls oblitsevat them around the boiler.
Important! The boiler is placed at some distance from the walls, it provides access to it when necessary. To discharge the products of combustion of the boiler needs to be done next to the chimney and bring it to the street.
Driving a private home heating system demonstrates the arrangement of necessary units.
Next to the boiler can be set Circulationpumps and distribution manifolds, expansion tank, measuring and control devices, shut-off valves. all pipe lines for the heating system will diverge from the boiler room. If the boiler has been designed in advance, and all the holes for the pipes to be prepared. In the case where the heating system is laid in the long-built house, will have to use hammer and punch holes for pipes, and after installation carefully to cover cement mortar. Pipes are installed in designated areas and are attached to the walls. The pipe system includes risers and eyeliner to radiators. The pipe joining method is selected depending on the material.
Important! to use a tow and a special sealant to seal threaded connections. Pipes made of steel and galvanized must be painted. So they last longer.
At the final stage the installationradiators. They are placed on the brackets, screwed or immured in the wall. Today, there are two types of radiators on the market: standard and enhanced. Reinforced radiators are designed for a system pressure of 16 bar, the standard - a pressure of 6 bar. If you choose to consider this feature. To achieve the best heat, the radiator should be installed so that the distance from the floor to the radiator was 10-12 cm, 2-5 cm from the wall, from the sill to the radiator 10 cm. At the entrance and at the exit of the radiator should be put locking and control valves. Thanks to her, you can adjust the temperature, shut off the flow of water or steam for repair or replacement.
Electrical heating: calculations, installation
Heating private homes with electricity gainedpopularity with the advent of modern convectors. These devices are installed on the perimeter of the room and under the windows. Electric heating private house has the following advantages: ease of installation and maintenance, cost-effective. Among the shortcomings should be noted dependence on the power supply, if there is power outages, it is necessary to put the generator on fuel. A significant drawback is the room air overdrying.
electric heating circuit includesconvectors, wiring and thermostat. Installing such a system will require minimal effort. Enough to lay wiring and install the heaters on the wall or on the floor.
The calculation for this system is as followsmanner. For a basis of the required power to heat 1 m3 of space. So much for the room must be well-insulated 20 W / m3 for indoor, insulated ceilings and walls should be 30 W / m3 for slaboizolirovannyh 50 W / m3. The necessary power is multiplied by the amount of space and is divided into the power of the convector.
heating device in a private home of aa species depends on the availability of energy resources. If the house is brought gas pipeline, it would be wiser to use it. In places where there is no gas, it is possible to install electric heating. If there are power outages, it is possible to use another form of energy, as long as it was available.
