    Anyone got a Vailant boiler?

    Do you have a woo based hard water doobry fitted to it?

  • I have one, an have no idea what a woo based hard water doobry is?
    The only issue I have is keeping the pressure topped up.
    Was installed about 12 years ago.
    No issues, and I'm in stockwell, which I believe is a hard water area..

  • Cheers guys.

    Was told that V won't honour their warranty if one isn't fitted. Was also told at the same time that they do nothing... the internet seems to agree.
