Solar thermal energy
Solar systems convert solar energy into a different, usable energy form. Thermal solar systems provide heat for service water and hot water.
How a solar thermal system works
The way solar thermal systems work is relatively simple:
A mixture of water and antifreeze circulates in the solar thermal system: the so-called solar fluid.
The solar fluid is heated by solar radiation in the solar collectors, which are normally installed on the roof.
The heat collected is transferred to a battery via a heat exchanger.
The hot water produced from this can be used as drinking or service water and to support the heating system.
The solar thermal system should have dimensions such that it can meet the hot water demand outside the heating season and be used to support the heating system in winter.
