Underfloor Heating - Existing House

KATM

Hi there,

I'm looking for some advice about underfloor heating.

We're in the process of updating our new home and as we've knocked the sitting room and kitchen in to one big room, the area (which is due to be tiled) is going to be very cold underfoot.

The builder has said that it's not possible to install underfloor heating in an existing house. Is this so? And if not, has anyone any other ideas? I've searched the SEAI website - but it's all like gobble-dee-gook to me...

TIA!

What about devimats? There not really for space heating but great at warming floors. In saying that at 150w/m2 they should heat most large rooms.

Thanks macnug! Is that the electric under-tile heating? I've looked in to that and apparently it's not terribly reliable. Having priced it (it's expensive), I don't think it would be worth the hassle or money if there was a chance it would break in a few months / years???

Thanks again!

Yea the undertile heating. I know a few people that have it with no problems, I had I in my old house and miss it in this one. When you think about it, once installed correctly, it should be more reliable considering there are no moving parts. Price is expensive though. If your thinking of getting a water based system id say your going to have to take up the floor.

What type of base are we talking about? Concrete or suspended timber?

I have UFH in a suspended timber floor, required some simple engineering. If concrete, you need to think about insulating underneath, to stop the heat going into the ground, so you would need to dig it out out OR loose room height as you lay insulation.

Maybe reconsider the flooring option, laminate tile effect, done well is very impressive (http://www.amtico.com/) and warm.

Thanks Macnug and Wallly Runs. It's a concrete floor - but think it might be too big a job to dig that up at this stage? Plus, we've already bought our tiles.

I might look in to the Devimats - are they expensive though?

Thanks again to both of you - I really appreciate getting advice from people in-the-know.

Underfloor isn't the B all and End all of heating. Maybe stick in a rad.
