Boiler Pressure Loss?
I have a problem where my boiler keeps losing pressure. I have had a new boiler fitted in the last few months but have/had the problem with both the old and new boilers.
It seems that when I go around and bleed the radiators etc. the problem becomes even worse in so much as when we get up every morning the boiler pressure has dropped to zero. Then over a period of months the problem becomes less acute and we just have to top up the boiler a little every week. I went and bled the radiators again and one particular rad had a LOT of air in it (just as before) which I bled and now we are back with the problem of the boiler pressure dropping to zero.
Is it possible that the radiator that keeps requiring a lot of bleeding could in some way be the problem be causing the pressure problem?
I do not have any water being discharged through the overflow and I have searched high and low but can not find a leak anywhere.
Any help much appreciated.
