  • Leaking carbon monoxide into the kitchen... so the current setup is going to require remedial work just to get it through to January.

    Carbon monoxide leak is registering at 175ppm around the flue, it should be below 10ppm (so says the Pimlico engineer) and above 6ppm should be cause for investigation anyway just to determine source and safety level.

    If this sounds wrong to anyone please say... but yup, his device is showing 175ppm when the hot water is heating, which is solidly in the not good area. The flue is basically venting directly into the kitchen (as well as outside).

    Anything above 35ppm and I get people out of a confined space at work. Any reading at all and we’d prefer not to have anyone inside.

    For an indication of cost, we recently paid just over £3k for a 35kw high-end Vaillant combi with smart controls, power flush, new thermostatic valves across the house and a new bedroom radiator. There was a fair bit of work involved in re-routing pipes/etc - they were here for three days IIRC.

  • Nightmare scenario. Glad you're okay and have found it now so it can be sorted.
