To install solar collectors allows to produce useful hot water for the heating system during the winter.
The generated hot water can be used directly in the circuit of heating or serve as support to diminish the consumption of the boiler, preheating the feeding water.
The solar collectors cannot maintain the temperature fixed to which they generate the hot water, so they worked of the two forms, based on the temperature to which are able to warm up the water.
For it, all installation of solar heating incorporates a interstorage cell, a hot water storage cell with double coil for the heat interchange. By one the liquid warmed up by the receivers and the other flows from the hot water of the boiler.
Of this form, when the thermal energy caught by the collectors can supply all the installation to the wished temperature, the boiler lets work. When no, it is the boiler the one that provides the heat necessary to reach the temperature of work.
It is possible to mention that the boiler will have to be determine the proportions to be able to provide the necessary energy to all the house.
The receivers also can warm up water for sanitary use, obtaining to a saving in heating and sanitary hot water from the 30 to 50%.
The heating system that better adapts to the thermal solar energy is the radiating ground, since it works to low temperature, around 40 ēC. In addition to being very healthful, it allows to save more energy than other systems.
To know more about radiating ground
If they are already had installed radiating, the solar energy can help to a large extent to reduce the consumption of the boiler. The radiators work to 70 - 90 ēC, very high temperature for the flat receivers common in winter.
In order to reach this temperature in winter, they will have to settle collectors of vacuum tubes, with better yield and than they allow to work without the support of the boiler in the sunny days.
Another system of ideal heating it thermal solar energy is fan-coils. Fan-coils works to low temperature, using the water warmed up by the collectors to warm up the air of an enclosure or the premises.
