I wonder if someone can help,
I've just had my old boiler replaced and a new Vaillant Ecotec 837 combi boiler installed. The plumber that we got to carry out the work claimed to be Gas Safe approved, however although the hot water works fine and the heating also seems to work, after around 12 hours the pressure gauge on the boiler was in the red and the display showed 3 bar.
I bled the radiators (As he told be to do) and after this the pressure was back down to the middle of the gauge. If I wait a couple of hours and go back to the radiators and try to bleed them again I get a lot of air coming out before water comes out. My question is, is this happening just because the boiler was only changed yesterday? and is it likley to settle down or could it be a sign of more serious problems? The central heating was fine with the old boiler (Non combi)
The reason for the question to the forum rather than my plumber is that I can no longer get hold of him, He hasn't given me a certificate and he did seem a bit too keen to get away yesterday after completing the work.
Given that I have my doubts about the installation I am not leaving the system switched on at night time and I will try and find a real Gas Safe plumber to check and commission the system as soon as I can on Monday
Any help or Ideas would be gratefully received
Neil
