    underfloor heating in a wetroom

    underfloor heating in a wetroom 13th Mar 17 at 2:01 PM
    I am in the process of fitting my wetroom and was thinking of underfloor heating as we don't have the space for a radiator.

    Now the Dimensions of the floor is approx 3m by 1m so what size do i need for the underfloor heating?

    I was thinking either 2m or 2.5m because i have a wall hanging basin and a wall hanging toilet so the heating mat can go all the way down on that side of the room but i was under the impression you dont need it under the shower and you cannot cut the heating mats

    presumably you are talking about electric UFH?
    imo that's not much use for space heating, it's fine for taking the chill off the tiles but for space heating you really want wet UFH

    yes electric underfloor heating, its just so the tiles dont be freezing when we come out of the shower.

    its not much space but for the price we are getting it just thought it would be worth it

    Electric ufh in a wet room that sounds like a good idea
    I'm only here while I wait for Corrie to start.

    You get no BS from me & if I think you are wrong I WILL tell you.

    Ensure you fit insulation under the floor between joists, the thicker the better . Expanding foam all edges to prevent air movement otherwise your floor may never reach its max set point

    If you use cement board as a final prep finish you will also be able to use 150w mats . Make sure the UFH is fitted, then screeded, then membrane on top to seal

    Common misconception that, electric mats can provide a higher heat output than wet UFH, nearly double.

    Most manufacturers will have set mat sizes but also loose cable systems for non regular spaces such as wet rooms etc.

    You do realise they have specific electric mats for wet rooms, bathrooms etc, don't you? Not an issue at all when designed and installed properly.

    Then would be good for you to read up on the current electric mat systems, they work really well. And I can only talk from my experience as a chartered building services engineer, and specifying and installing ufh systems for 20 years.

    Good stuff, do you do cost calcs for the systems etc too - could you drop me a pm with your details on it?
