I was wondering if anyone can help. I have a multitherm electric boiler in a sealed system. We recently had a blow out and had to replace the heating element, thermostat controller in the boiler and the pressure guage with the vent. Once the system had been turned on again and the pressure set to 1bar cold everything seemed to be fine. But through the evening the pressure seemed to drop. When hot it never goes above 1 bar and when cold is slowly drops to now just under 0.5 bar. I can feel that at least one of the radiators has air in it. Could this be the problem? and if so should I just re-pressurize and bleed the radiators till I get the system to 1bar cold?
I can see no leaks and am not sure where the air may be getting in.
Many thanks for any help you may be able to give.
