A rare inhabitant of the metropolis does not dream of own country house, located in a quiet area, close to a picturesque forest. No noisy neighbors, no stuffy streets or constant buzz transport stream - the benefits of such a choice, really, a lot. However, in this situation on the shoulders of the owners go to all the trouble utility. In particular, it will have to organize its own water heating system in a private house, or with the advent of cold weather will have to return to the apartment. Of course, the modern market offers a variety of options for home heating, but the water belongs to the technology to the category of classic, time-tested, proven its reliability and efficiency in the harshest conditions.
The benefits of choosing
Water heating of a country house has the following positive features:
- Installation is possible at any stage of the construction of the cottage, not necessarily the plan is still in the design stage, may be installed even in a finished and inhabited building.
- Water - the best in every sense of coolant. It is also characterized by a high degree of thermal conductivity, and low price, and the incidence and the highest heat capacity.
- Versatility. For this scheme, suitable and electric heating private housesAnd the use of gaseous fuels and wood, and oil.
- Constructive variety. Heating circuit suggests various options for wiring pipes, the final scheme is selected according to the area of building the financial capacity owners, and other requirements.
- Individual assembly on each battery check valves ensures that the temperature with high accuracy can be adjusted each separate room, the climatic conditions in adjacent rooms, as well as parameters of the system operation, not to change will.

Features of the device and the selection of the circulation circuit
private home heating system operates on a fairly simple principle. The boiler heats the coolant, whether it is water or a special solution, which pipe system reaches radiators disposed in heated rooms. As the cooling heat medium returns to the boiler, the cycle is repeated.

Circulation is based on one of the following methods:
- The natural process is based on the difference in the density of the hot and cold water. In the process of heating the liquid density decreases, the proportion decreases, and because it starts moving upward through the tubes. As the cooling, on the contrary, the density increases, the solution tends downward. The main advantage of this method - the absolute autonomy, independence from the electricity, as well as the constructive simplicity. The main disadvantage - increased consumption of materials, circuit consists of a large number of pipe diameters impressive. Furthermore, when mounting deviation should be maintained at about 2 degrees.
- heating system one-storey house with a circulation pump. Excess water, which are formed inevitably upon heating, are inside a special expansion vessel is usually closed, that prevents the phenomenon of evaporation. Additionally, be sure to put pressure gauges, pressure control. Advantages of such a process is the minimum required amount of coolant, a minor diameter pipes and their lower expense. The main drawback - the dependence of the power with which the private sector often has problems.
- Combination. The pump is installed in the circuit have made with natural circulation. This embodiment operates without a pump, but with the inclusion of its power and efficiency is increased significantly.
The number of circuits and wiring options
Driving water heating private houses, ideally, it should be based on the creation of two circuits. This approach is much more convenient. The first loop operates on heating, i.e. delivers the coolant to the battery, and the second delivers hot water to the consumption points, the kitchen, to the bathroom.
However, if the tenants previously took care of the installation of the boiler or water heater, this condition is not necessary.
If we talk about ways of wiring the following options:
- Scheme with a single tube, through which coolant enters the each of the radiators. The advantage of such a decision in its simplicity, to minimize labor costs and cost reduction. Unfortunately, for simplicity have to pay absence of possibility to control the temperature of each battery individually.
- Driving with two pipes better in terms of operating temperature can be set quickly and precisely, all the radiators heat up evenly.
- Manifold scheme assumes that the supply and discharge of coolant occur in different tubes, a single functioning system through the collectors. Such circuit looks attractive and aesthetically pleasing, adjustable temperature of each battery individually.
Choosing boiler
All kinds of advanced water heating in a private home operated through the boiler. He is the heat generator. On the market are well represented model, running on the following fuels:
- Gas. The most demanded option. The reason for this - the low price of gas with significant efficiency, ease of operation and minimum noise. The disadvantage is, in fact, one - the need to obtain numerous permits to connect to the main gas pipeline.
- Electricity. The optimal option in terms of safety in the home. To do this, the unit does not need to choose a special place to install, it takes up a minimum of space, does not emit combustion products. Unfortunately, the device is cheap to use, in addition, in rural areas are often energy network quite worn out, there are disruptions in the supply of energy, it also imposes certain restrictions on mounting.
- Liquid fuel. The design is very similar gas analogs except burner type. They need a separate room arrangement boiler produce enough combustion products, because of which require regular cleaning.
- Solid fuels. Heating with them is very cheap, in the private sector rarely have trouble finding and purchasing the wood. The downside is the need to regularly enclose the fuel in the furnace, clean out the ash.
- Combined heat sources able to use multiple fuels, causing considered the most reliable choice.
Boiler capacity can be selected on the basis of the following scheme: in need of kilowatts per 10 square meters of space for the southern areas to central - half kilowatt, northern - two. However, experts recommend to add to get the value of 20-30 per cent to equipment coped with severe frosts.
Select the pipe material
Properly fitted pipes will eliminate many of the problems in the operation, ensure a high level of system reliability:
- Popular earlier steel variants recently used infrequently. This is due to the difficulties during installation, corrosion susceptibility even in the presence of the protective coating.
- Metal-easy to install and durable, but his weak point - screwed connections and fittings that can deform during sudden changes in water temperatures that will trigger the loss of integrity and leaks.
- Copper. In every sense a great option, but it involves significant financial costs.
- Polypropylene - a golden mean. Durability, flexibility, corrosion resistance and temperature variations - different elements all these qualities.
Choosing a battery
It is also important to choose the right water cooler:
- Steel. The main advantage - the democratic price. Minus - susceptibility to corrosion, due to which the service life is considerably reduced.
- Aluminum. Resistant to corrosion, heat up fast, but vulnerable to pressure differences. However, this phenomenon is more characteristic for systems in apartment houses, detached cottage in this regard is quite stable.
- A combination of metals. They combine the best quality steel and aluminum.
- Cast iron. Familiar to all from the Soviet era. In essence, eternal, but heavy, requiring the use of high-power bracket during installation.
Installation Instructions
Water heating private houses with their own hands settling down as follows:
- Mounted boiler. Place for him should be chosen so that to simplify pipework and reduce material costs. If you put a gas or electric version, you need to remember about the convenience of connecting to the mains or wiring. mounting height plays a role only for circuits with natural circulation, the lower part of return pipe, the better.
- Installation of water heating radiators in a private home. The batteries are placed under the windows, which contributes to the exchange of air. When mounting should strictly maintain the horizontal and minimal padding: 10 cm - on the windowsill, 6 - from the floor. Ideally, you should immediately install valves for emergency shutdown and air bleed.
- Distributing pipes, the installation of auxiliary devices. This process starts directly from the heating boiler on the basis of pre-designed circuit using connecting elements, including the corners, fittings, tees and other. His house can be equipped with wiring and open (the pipe is always in sight), and a closed circuit (the details are hidden in niches). Together with the pipes is also connected batteries mounted circulators (if technology suggests their presence), expansion tank, filters, safety blocks, safety valves other.
Thus, it can on its own to create a reliable, durable and efficient heating system that does not fail in the most severe frost!
