Dear all,
There is always drop of pressure in the system, when I fill it to 1 bar, then a demand for DHW and CH is made, the pressure build up gradually as the system heats up and the pressure gauge registers over 3 bar. I also noticed that the Auto Air Vent leaking very hot water from its little black cap. One week later the pressure gauge reads 0 bar when the system is cold and around 2 bar when the system is hot.
My questions are:-
Is this normal?
Is the Auto Air Vent faulty and needs to be replaced?
Does this effect the demand for the DHW as the system shut down sometime closing the gas valve when there is a demand for DWH only?
Many thanks
