What is Solar Heat?
Vario solar systems use the sun energy by collecting it in the solar panels and transmitting it through a highly selectively coating to the support pipes. The collected energy is delivered to the heating system and produces heat or hot water. If the temperature on the roof is higher than the temperature in the boiler, the circulating pump activates automatically. The heat is conveyed from the roof to the boiler for hot water or heat production, as required. The circulating pump combined with a solar regulation arranges for, that heating and hot water are always available – of course, when the sun shines.
