    Have I possibly damaged the underfloor heating mat?

    So I’m fitting an electric underfloor heating mat by pro warm. I was testing it for continuity between L N and got 88ohms which is what it should be according to the instructions. It says to do IR test at 500V but it doesn’t say between which colours. So I did L N and got 0.00ohms. Have I...

    Is bathroom underfloor heating still notifiable?

    All the specific guidance I can find stating that underfloor heating is notifiable seems to refer to an outdated version of Part P, and I’m trying to understand why generally everywhere still treats it as notifiable. If a dedicated cable already exists from the consumer unit (so no new circuits...

    Underfloor heating repair

    Hi all, Got to look at a job where the builder has cut through the underfloor heating mat and it’s gone right through the heated cable. Not something I’ve ever had to do before. Any one else had a go at repairing this type of thing ? Would it be sufficient to just strip back the insulation on...

    1950s underfloor heating brought into reuse with air source heat pump

    My mother moved into her three bed home in 1960 and it had underfloor heating in the living room. I remember we used it when I was growing up in the 70s but it hasn't been used for probably 30 years. Electric storage heaters were installed to take advantage of the old off-peak electric tariff...

    underfloor electric heating as an afterthought without dedicated wiring

    I'd really like to install underfloor, electric radiant heating in my bathroom. The space to cover is very small, probably 25-30 sq ft. once the tub and vanity are factored in. Not having planned for this, we don't have a dedicated breaker for it. Current set up: we have two junction boxes...
