  • Has anyone laid underfloor electric under engineered wood? I have a fully insulated shed/garden room with fancy wood flooring - 20m2 room, I’d like to put 16m2 electric underfloor into it. I can get 2m2 rolls cheap, but I’m not sure I can plug 8 of them into a single thermostat - does anyone have any experience/know why I couldn’t? Thank you

    Hopefully right thread now…!

  • I think the thermostats have a rating in amps and so do the sheets. I bought a couple to replace some broken ones the other day and I'm pretty sure they were rated for 16amps (which seems to be standard unsurprisingly)

    So you would need to have 2amp max draw from each roll.

  • I have 2 mats (15sqm in total).The tails terminate in a fused spur, which goes to the thermostat.

    With more, you'd probably need a terminal block.

    The draw scales pretty linearly with area - given you can buy 20+ sqm mats, and they happily use one thermostat.

    I had a sparky do the actual work, as it was being fed from a new CU.
