hello ,moved in to a new place ,it had been empty for a year ,checked the boiler, water pressure and set it at 1.5 bar ,after 2 months now the pressure drops if it stands for a couple of hours.
checked to see if there were any leaks every where = none .
i was used to working on older types not condenser one ,so does the expansion tank have to be pressurised if so what psi ,im guessing that there has to be some sort of valve that dumps excess pressure to the pipes outside
are these valves prone to sticking? dumping the water out ?
any help would be appreciated .
