3.4 Checking the operating pressure, topping up with heating water and bleeding the
system
3.4.1 When do you need to check the operating
pressure?
Newly added heating water loses much of its volume in
the first few days because it releases gases. This caus-
es air pockets, and the heating system will start to rum-

bleeding the radiators if needed.
Later, check the operating pressure monthly, topping
up heating water and bleeding the radiators if need-
ed.
