  • One thing to consider maybe is that Viessmann doesn't have installers in London. When I contacted them they could only give me one company in Cardiff.

    Good call... did you go for it anyway?

    I asked a heating engineer what he thought, he concurred that installation is hard (extra training he hasn't done) but that maintenance is a dream.

    He recommended that if I'm looking at that level of quality that I investigate Worcester Bosch as there were more installers, efficiency is nearly equivalent. He suggested something like this https://www.worcester-bosch.co.uk/products/boilers/lifestyle

    Though most of what he told me was not to change the power of it without doing a full site survey as the gas run might not support a higher rating anyway and then it would be less efficient. So his main advice was: Do nothing and make no choices until you've had a full site survey.

    So it's not like I'm making any decision for a long time.

    I don't think reliability is anywhere near Vaillant though, although it's a while since I researched boilers. All the good installers seem to recommend Vaillant.

  • Thats pretty much bs, every installer has there preference. The years of shit boilers and one manufacturer being better than another is really over. They are all offering long warranty's on them now. Worcester as much as they win which are so over priced its unreal.

    The new Baxi stuff is pretty good, weissman's are decent as are valliant but they all have long warrantys now which you just pay for in the price of the boiler. Worcesters are the worst to work on from experience.

  • I'd look at the guarantee length, but have two properties with different valiant boilers both have had the same issues common issues with combi boilers of the diverter valve and the pressure sensor.
