Also, does the pressure rise when the boiler is off?
Where does this steam come from?
When the boiler is off the pressure is fine. when we have it on just for heating tap water the pressure is fine, it's only when the heating is switched on that problems seem to start happening. the problems wasn't the pressure raising though , it was still working we just noticed a a bi of water coming down the wall downstairs under where the boiler is and soacking through the wallpaper, the trickle only appeared when the heating was on. Turn the heating off and just have the boiler on for heating tap water and it was fine. I think it was just a corroded pipe or something as we did notice a small drip coming from under the boiler when the heating was on.
The steam came from underneath at the bottom of the boiler, that happened after they'd gone and had never happened before, I turned it on to see if anything had changed, the blue tap was loose so I tightened it to how it should be. started hearing a funny noise as the temperature started to go up and heat the water, then steam just blew out the bottom and I turned it off straight away.
We've got in touch with someone else who just fit boilers and they are coming tomorrow to have a look, over the phone they gave my mum a few options starting at around £1000 going upto £1600 which seems a bit fairer, that wasn't cash in hand either and comes with a 7 year warranty.
I'm convinced these guys have purposely opened the tap to keep the pressure rising to blow something.
