First of all, it should be noted that todaysingle-story country houses - a rarity. Most of the cottages are built in two or three floors. Of course, two-storeyed houses are the most common: in comparison with single-storey houses there is much more living space, and in comparison with three-story houses they are built faster and cheaper, including due to a much less powerful foundation.
However, the heating system of a two-story house mustcope with the heating of all rooms with the onset of cold weather. For this, it must be appropriately arranged. Therefore, the scheme of the heating system should be determined before the construction of the house.
There is a great temptation to choose a scheme withnatural circulation of the coolant, since such a heating system of a two-story house is independent of electricity. However, in order for it to work, it will be necessary to use large-diameter pipes in communications and to carry out layouts on a slope. These disadvantages may eventually outweigh the "energy" plus.
Scheme of the heating system of a two-storey house withforced circulation of the coolant is optimal: the water does not stagnate anywhere and evenly enters all radiators. It is understood that in the house or under it there will be installed a boiler operating on wood, coal, kerosene, natural gas or electricity, an expansion tank, a collector, and also a circulation pump directly responsible for the circulation of water in the communications.
It should, however, seriously think about what material they will be made of.
Of course, and up to two-story cottages got"polymer revolution". Polypropylene pipes are not only the convenience of non-welded installation (which can be done without professional qualification), but also the inability of internal salt and lime deposits, resistance to corrosion. One problem: the polymer has a large coefficient of thermal expansion, which causes deformation of polypropylene pipes and can lead to leakage at the junction points. This defect was tried to eliminate by reinforcement with a thin aluminum layer. Indeed, metal-plastic pipes are almost insensitive to thermal expansion, but such pipes and fittings are not cheap, to put it mildly.
More difficult to install pipes made ofstainless steel or galvanized steel: Welding or reliable threaded connections are necessary, and all operations must be performed by qualified specialists. They cost more than polypropylene, tend to overgrowth, and their service life is low.
The heating system of a two-story house can beis built on the basis of copper pipes, if the owner of the mansion is sufficient for this facility. For their mounting, high-temperature brazing and solder with silver content are used. However, the benefits of copper communications ultimately exceed their cost: they are resistant to high temperatures and high pressure, do not overgrow and do not rust, they can be tightly sealed in the walls of the house. Service life of at least half a century.
Usually for heating two-story houses offersingle-pipe and two-pipe wiring systems. But the one-pipe heating system of the two-story house does not have any possibilities for adjusting the room temperature - it is impossible to cover one of the heating radiators while others are working, and hot water, passing successively from one battery to another, can reach the last one already cooled.
It is quite another matter if one tube per systemhot water arrives, while the other one, already cooled, leaves for another heating. Such a two-pipe heating system of a two-story house is universal. In this case, it becomes possible to separately adjust the heat transfer of each radiator by increasing or decreasing the flow of water passing through it. Advantages of such a system slightly reduces the double set of pipes laid at the same time.
Absolutely universal scheme of water heatingtwo-story cottage does not exist, in each case it will have to be selected individually. The ultimate goal of such selection is obvious: the most rational warming up of housing.</ p>>
