Modern many promising confrontation of subject of heating of space, is the use of solar collectors for the warm-up of water of thermal bodies and hot water of use. Are used solar collectors (similar with those of solar heaters). The hot water is led in suitable dimensions reservoir of storage with which are connected the boiler of radiator or the stove, or the electric system of heating, and that supplement also the required energy.

Apart from the drawing that appears dipla exists a interesting variant. The auxiliary source of heating is not connected obligatorily with the unit of storage but straight in the thermal bodies. Such something appears to increase the solar rewards.
