What is the hybrid air-liquid collector?

The hybrid air-liquid collector is a collector that works with two heat-using materials. Both air / water and air / glycol-water are used. This hybrid concept is perfect for our climate. In the summer months, temperatures in the Czech Republic are often up to tropical, which can heat the collector up to 50 ° C, which is more than enough to make hot water. In colder periods, collectors can not warm up to more than 30 ° C, but still it is enough to heat the air in the building.
