Ha Ha - only Stella not Carlsberg Special Brew !? All good now

TCC - a thousand thankyou's ! Just bled the air out of the tank using the valve you mentioned and now the water temp is a steady 55C and the temp gauge no longer rockets to 103C when trying to keep up with the flow. Sure was a lot of air in the tank, had to re-pressurize the system , but...

TCC - quick question. This air vent on top of the water storage tank, would this be the black plastic device about 2" tall and 1" diameter ? If so what do you do with it ? I suspect my installer is a little 'green' when it comes to this model of boiler and I want to point him in the...

Thanks TCC Heating - sounds like the ideal solution. Still waiting for the installer to come over - I'll mention that to him. Did try the service level 1 air purge program but didn't seem to make much difference.

During the install the engineer checked the gas pressure and pipe sizes etc plus our gas meter is relatively new (<3 years old) so I doubt it's gas starvation in this case. But as St0mer66 says - remote diagnosis is not a perfect science, however in this case I suspect he's correct and it...

I could bleed them myself as it's a straight forward job and he's shown me how to do it. But for now I'll let him take care of it. So I assume the excessive indicated temperature and the rapid rise of said temp is associated with excess air ? Seems logical.

The pressure gauge reads just over 1 bar and is steady at that reading. I agree it's most likely not fully bled, plus there's air in the upstairs radiators. So I'm hoping a good 'bleeding' session might sought it out. He's coming back later today to get paid - so I'll mention it then...

Hi guys, Sorry for the length of this post, but I've just had a W-B 440CDI boiler installed, on paper and from reviews it seemed just the job to heat and provide hot water for my 4 bed detached bungalow. The guy who installed seemed to do all the right stuff, like flushing the system etc...
