Remove dirt and snow from the collectors whenever
snow is more than 50 cm deep. Increased dirt lowers
the efficiency of the solar thermal system.
Have your solar thermal system serviced regularly to

ensure trouble-free, energy saving and environmen-
tally responsible operation. For this, it is recommen-
ded that you take out an inspection and maintenance
contract with your local contractor.
