This is how solar heat works - the most environmentally friendly heat of all

Solar heating

Solar heating is a collective name for the technology that converts the sun's radiant energy into heat. In everyday speech, this refers to the entire solar heating system that takes care of and stores heat energy. This normally happens with solar panels as energy collectors. This technology should not be confused with solar cell technology for electricity production.

Solar heating system

There are different types of solar heating systems with partly different areas of use. The basis of the solar heating system is the solar collector, whose task is to convert the incident solar radiation into heat. The heat is passed on by the system to some useful purpose.

Liquid-borne solar heat consists of a solar collector that contains water and some form of antifreeze, or a special solar heating oil. The oil has the advantage that it does not boil so easily (approx. 200 ° C). Airborne solar heating has a construction that has the task of heating air directly. The airborne variant has a less complicated construction, which makes it cheaper. The liquid-borne can be controlled for various uses such as heating hot water, buildings or, for example, a swimming pool. If an accumulator tank is connected, the energy can be stored around the clock.

Solar heating systems are combined with other heat supply during the winter. The most common combination is a wood boiler with an accumulator, but solar heating systems are also combined with pellet boilers and heat pumps.
