    Vaillant 837 mains cable run

    But how patronising are you? You know nothing about me. And because I ask a simple question you automatically think I haven't the ability to install a boiler. To be honest I think plumbers (or whatever you are called) try to mystify their trade and belittle intelligent people for doing what...

    Vaillant 837 mains cable run

    Ok a very simple question about the electrical connection on the Vaillant ecoTEC plus 837. I have installed the boiler and very well it went too, but I can't see how to run the mains cable into the boiler, as soon as I put the front case on it squashes the cable. I can't find where I can run...

    And whilst I have your attention... If I were to replace the boiler, is there a Vaillant one that will 'almost' match up to the existing plate, (you know the bit at the bottom of the boiler that all the pipes are connected to) and how much work has to be done to for the flue end as well...

    Vaillant 242 EH Laeakig from water section

    Yes, the centre of the boiler, the valve that has the white plastic dial that controls the domestic hot water temperature. The heat exchanger is what is being referenced here, I changed that about 10 years ago for the stainless steel type. So what I'm looking for is the valve in the...

    Vaillant 242 EH Laeakig from water section

    Hi I have a Vaillant VCW GB 242 EH that I purchased and installed in march 1992. Over the last couple of months a drip from the water section haas progessively gotten worse, to the extent that I can ignore it no longer. Looking for the whole water section on the internet has thrown up a...
