If you decide to build a turnkey house, then a lot of attention must be paid to the heating system, because it is she who makes a private house comfortable and enjoyable for living. In a private house, you can use various water heating schemes. There are single -circuit and double -circuit schemes, diagrams with one or two pipes, as well as different modifications of boilers and tanks. Additional devices are also used, such as thermal controllers that allow maintaining the optimum temperature in the house and at the same time significantly save on heating. Circulating pumps are also used, which generate enhanced pressure of water running through heating pipes.
The principle of single -circuit boilers is that they have only one direction of action: either hot water supply or heating devices. Double -circuit boilers are characterized by higher power and are capable of functioning in both directions. If a small amount of water is consumed in the house, then the installation of a double -circuit boiler is advisable, although you need to choose a fairly high power. However, the most common water heating scheme of a private house is two single -circuit systems. This scheme allows you to save about a quarter of the entire amount of energy costs, because two systems work independently, and in hot weather you can use hot water, not starting heating.
One -pipe and two -pipe systems at a price practically do not differ from each other. The first option for water heating of a private house is based on a single pipe passing through all the batteries of the house. In the second version, hot water is supplied along one of the pipes, and the cold is drained along the other. Thus, a two -pipe heating scheme provides uniform heating in all rooms while a single -pipe scheme in turn the room heats up much more than others.
In the process of designing a water heating scheme of a private house, it is necessary to take care of various details, including indirect factors, such as the angle of inclination of the sewer pipe, as well as the passage of the ventilation system and other communications. Remember that if you make a mistake at the design stage, then subsequent alterations will cost enough road. The role of pipes in the process of designing a water heating scheme of the house is quite large. Aluminum, due to their high thermal conductivity, are more often used from metal pipes. However, both steel and aluminum pipes have exposure to corrosion. Corrosion can be dealt with by galvanizing, however, with galvanized pipes, you should handle carefully, because if the coating is damaged during the installation process, the pipes may begin to swell, and the rust will form at an increased speed. Such troubles do not threaten polymer pipes, but they are sensitive to temperature differences, which is why cracks may form over time on such pipes. The ideal option is copper pipes, characterized by reliability and excellent thermal conductivity. Their only drawback is the high price.
When developing a water heating scheme, a private house must first be laid the boiler of suitable power. Usually proceeds at the rate of 1 kW per 10 square meters in a room without windows, if there are two northern or eastern windows in the room, then a power of 1.3 kW is taken, if two western or southern windows, then a power of 1.2 kW is needed if the window is needed there is only one room in the room, then there will be enough boiler of 1.1 kW. Given the variety of various options for circuits and additional devices, such as thermostat, it will be completely easy to choose the best option for a private house for a private house. It is important to remember the responsibility and accuracy of calculations, because heat is the most important indicator of comfort in the house.
