    Vaillant EcoTEC pro 24 - S0: No heat demand?

    Hi. So, I've fired up my 15-month old Vaillant yesterday, as it's getting a bit cold. First time since March that I've had the heating on. However, it doesn't really do anything. It makes the usual noises when I manually switch the CH on (via the attached Nest heatlink's button - just to...

    Vaillant EcoTec Plus 24 - very loud buzzing

    Hi. I had a Vaillant EcoTec Plus 24 installed back in September 2015, and recently it's started making an incredibly loud deep bass humming/buzzing sound that literally shakes the whole flat. I initially thought it was upstairs neighbours drilling into the masonry - it's that loud...

    Dry lining fastenings rusting

    Low System Pressure - what is this?

    Hi, My Potterton Puma 80 combi boiler has just started displaying this - so there's no central heating or hot water ;-( It was working fine for a couple of days (only fired up the central heating then), though one of the radiators never got warm (so based on a suggestion on this forum I...

    One radiator cold

    Hi, just bought my first flat a few months ago - now that it's getting chilly I fired up the central heating. All the radiators hot apart from the one in the living room, which is very cold apart from some very faint warmth towards the top and right. Have tried bleeding it and no air was...
