This one does have a heat store. Maybe I should of said it's an 105e Instant...... Definatly got a heat store, that was the big selling point when I decided to go with that model. Seems to work pretty well too when it's not losing pressure. Haven't tried the PRV thing yet, I figured that I...

Well I'm still learning so don't ask me. Two thoughts - does the boiler make any odd noises? If it only does it when the thermostat is turned up then could the thermostat be faulty? Mine's at about 75% and the radiators are too hot to touch. Even at 50% they get hot enough to heat the...

Thanks for replies. When the CH is on the pressure goes up no more than 0.5 bar - usually around the 1.5 mark. It seems very happy in CH mode. I just can't understand how air is getting into the system and the pressure going down. PRV valve?? That's the pressure release valve that...

Had a problem with the pressure dropping in my Baxi 105e, eventually decided (with advice of plumber) that it was the pressure vessel. Sure enough when I spent £100 on a replacement, the old one (when upside down) let water out of the air valve so I assume that it was indeed faulty. Problem...

My problem is the pressure keeps going down. Maybe we should swap pressure vessels... The pressure vessel only has water flowing through it when the HW or preheat is on. The central heating bypasses the pressure vessel. (Although it's still connected and acts like a normal pressure vessel...
