underfloor heating

Trez

can anyone advise of good system

Mr_Warren_2

It all depends if this is for a new build (extension) or an existing room. In the new build you can have a "Devi-Heat" cable which is a long electrical cable burried under concrete that when powered up, dissipates the heat through said concrete and tiles above.. I have just finished my conservatory and that same system works wonders. For existing build you have the possibility to fit a much smaller system directly underneath your tiles (a small thin cable supplied on a rolled mat that you cut (the mat not the cable) to the shape of the room. Both systems are controlled by a room thermostat. The other alternative that I have never tried is to use a wet system of pipes with hot water inside. I would expect this to take longer to heat the room up. I hope this answers your question.

You haven't given any indication of exactly what kind of floor you are wanting to under-heat.

About 3 years ago I fitted a new bathroom, including electric undertile heating. This is just a long cable which you snake up and down on top of the floorboards, tape it all down (special tape provided in kit), then simply tile over the top (using a thicker bed of tile adhesive than you would normally use - and it needs to be decent flexible tile adhesive, I think the adhesive cost almost as much as the tiles!!!).

The electrical connection was pretty straightforward if you know what you're doing, *BUT* new regs have come in since I did mine and you'd need to get it certified, or better still pay a qualified sparky to connect it all up.

The Under Floor Heating is fantastic by the way, and if we ever move house it's the first thing I'll be getting done

I would never of thought of putting in electric underfloor heating in a bathroom.

I'm really interested in this as we are about to put in a new bathroom suite and removing the radiator would be a big advantage as the room is quite small and wall space is limited.

Are there any special requirements (electrical regs etc) ?

Is it expensive to run ?

Being in a bathroom, the installation needs to be certified by a qualified Part P person. It's easy enough to do and perfectly safe (if installed correctly!!)

Regarding running costs, I didn't notice any dramatic increase in my electricity bill after it was switched on. Going from memory, the cable is about 300 watts, and is plenty enough to heat my bathroom (approx 2.5 square metres of floor). It's fully timer and thermostat controlled so it's not actually "on" for a great amount of time each day.

basically falls into wet, ie from the central heating system underfloor and dry electric underfloor systems. What is the room existing type of floor proposed finished floor material etc. then can suggest. with regard to electric underfloor you will dramatically reduce costs if you plan the installation. We use warmup as a company and they are good though many of them are fundementally the same.

Thanks.

My bathroom is only small. 1600x2300. The bath will be along the 1600 side hopefully 1600x800 (not bought it yet). Along the remaining 1500 of the 2300 wall, I hope to fit a basin and toilet. With the door facing on the other 2300 wall, opening onto the remaining wall. I may fit a tower rail here if it fits 600m wide x ??? high.

This should leave me with floor space that you could stand on of about 900/1000mm x 1500mm

The current floor is T&G floorboards, but I am planning to install a tiled floor over the top. I am worried about getting to pipe work later though.
