My boiler had a similar sounding fault. See the following post:

ZIGGY786 has a problem with his Vaillant Thermocompact boiler. He has screed underfloor heating downstairs and floating floor underfloor heating upstairs. He also has a hot water storage tank upstairs in the loft and the boiler is in the kitchen. He used to lose water pressure on his...

It's done now - insulation resistance tested before and after plastering. All is good. Thanks to the people who helped :)

What?

Great :) Thank you!

Hi Ricicle I'm aware that there are regulations, but I don't know if I know what they all are yet. Regarding notifying, this is part of a larger renovation project for which building control is already involved. The circuit won't be "livened" up yet - I'm just chasing in this cable so...

Hi I want to chase a cable into the wall above the sink in my bathroom, and mount a light on the wall. The cable will run vertically and connect to the lighting circuit via an existing ceiling light rose. How deep does the cable need to be in the wall? Also, can it be capped, or does...

Thanks to everyone who contributed on this topic, especially Andygasman10 and The831Bunny, who each took time to address the questions in the opening post. To those people who thought that I wanted to fault-find the unnecessary firing problem - thanks, but I had already diagnosed that problem...

Impatient? I don't think I am. Nor am I ungrateful - I've been thanking people left right and centre. But in return, as well as the free advice, I've received 'free' abuse, in the form of sarcasm and personal comments.

130330 is actually what I've ordered - I just wanted to see your reaction ;)

Call it what you like, but the bypass valve came in a Vaillant box and was bought at Parts Center. Thanks for those figures Andygasman10. If my understanding is correct, the NTC thermistor is used (along with the user control knob setting) by the temperature control PCB to modulate the...

Thank you Bunnyman for some sound points. I had already identified that this is a hybrid model and Vaillant gave me the part number for the main PCB, but thanks for the tip-off. The bypass valve for this boiler cannot be fitted the wrong way around because it's incorporated into an...
