Hello all, I have done a quick search but couldn’t find anything that matched all of my problems. Well here goes.
The problem is the boiler is constantly loosing pressure and causing the warning lights to flash meaning no hot water. This happens when just using the hot water or hot water + CHs. After speaking to a chap at Alpha I went through the following:
Bag over PRV – no water coming out.
Closed flow and return valves on boiler to isolate CH – pressure loss still occurs.
Now after opening the filling loop to reset the pressure the loss can occur after a few hours, or almost straight away. Sometimes you can watch the needle go from the green into the red.
I have had the person who installed the boiler take a look. He replaced the PRV and filling loop and gave it the all clear but it still has the same issue, and now he says that it is just air in the system that is causing the problem and that I need to bleed the rads.
Well yesterday evening I turned up the CH, turned off all the rads, and then opened each one fully intern and bled them (5). After I done this the boiler pressure gauge was in the middle of the green and every radiator was red hot. Left it like this for a few hours and all was ok.
At bout 10ish I turned the thermostat for the CH down and went to bed. Woke up this morning with the boiler pressure valve on zero, but no warning lights. Ran a hot tap and the warning lights came on. Back to square one.
I am at a loss at what to do. I need to get it fixed but am loathed to call out said engineer as he seems to think the boiler is fine when is obviously isn’t.
Cheers
