Remeha Avanta combi boiler losing pressure.

Yes use filling loop to bring system pressure back up to 1 bar ,in conjunction with bleeding air from radiators ( draining water out lets air in ). Then monitor regularly the boiler pressure when c/heating is on. It shouldnt really get to 2 bar when hot if the ev is in good nick ,and you have charged it correctly. If it continues to lose pressure ( and the prv isnt letting water out ) then heat ex would be suspect.
Unfortunately ,i have a lot of time on my hands ,( bad back ) went back to work monday after a while laid up ,and lasted half a day before back went into spasm. So i am sitting around again bored stiff !!! Got any jigsaw puzzles you dont want

Have you checked the air side pressure of the EV? This needs to be done and pumped up whilst the water side is depressurised. You need to open a drain cock (on boiler or system NOT PRV) and allow water to pulse out whilst you inflate the EV.

Just sayin'

Hi - I might be outside my comfort zone on this as I'm unsure what is needed.....and I do not have a pump!

And it turns out barney has got a pump after all !!!

Hi - I only have a 12v pump for the car, so I will be round to my neighbour again to borrow his pump. I think he's away at the moment so it will probably be in a day or two.
