How Can I Make An Electric Undermat Heater?

    Hello,

    We have electric underfloor heating (Warmup) in a new build house.

    We didn't get any heating in the bedrooms (it's a passive house) and while most of them are fine our bedroom is a bit cold.

    I'm not that keen on having a panel heater on the wall so looking for an option to have "underfloor" or similar heating under a large rug (2.5 x 1.5m) at the end of the bed. I can run a power cable to there without it being visible.

    I ordered one of these: https://www.bewarmer.co.uk/product/rugbuddy-under-rug-heater/

    But I'm not that happy with it so may send it back, it's infrared heating so does not really heat the room/air in the room, it's also very expensive.

    What I was wondering was could you get a traditional underfloor heating mat like this:

    https://www.warmup.ie/products/heating-mats/pvc-heating-mat

    Place a thin layer of insulation under it Warmup have thin boards so it does not damage the wooden floor) and have a rug on top.

    Would this work? I don't know if you could just stick a plug on one of these. They are generally not wired for them.

    We do not need much heat here, 500w would be fine.

    Any advice would be much appreciated.

    Thanks!

    Lots of things might work but no one is going to recommend using a product like the warmup mats for a purpose it is not intended for.

    The rug won't hold the heat like a tile or stone floor would, waste of time and money.

    That rugbuddy is the safest way as it's sealed and is IPX7 rated and can take spillages. Otherwise if you do a DIY solution you'll have a problem with AC mains voltage going into the rug and little or no insulation protection on the heater.

    Stick with the rugbuddy or consider putting it on a motion sensor of some type so that it comes on when you are moving around the room.
