as above , i need to cover approx 15m2 , the fllor at the moment it concrete , i want a layer of heating then to tile ontop of the heating.
running costs decide which system ill put in .
does anyone fit it or know enough about it . i am thinking the pipe one has surely got to be cheaper? also how many btu roughly will 15m2 be ? . also do you have to put a foam 'frame' that the pipes sit in?
cheers

My college project was to design an extension on a house and i went with underfloor heating. Cant remember exactly what the build up was but there was insulation above the slab and the pipes ran in the insulation. Laminate on top but i think there must have been adhesive in between parts.
Youll probably get other methods of underfloor heating as well though.

the wire would be easiest. foil insulation ontop of the slab, wires laid out then tiles on top of that

Using water you'd end up raising the floor by about 100mm. Damp first, 50mm insulation on that, pipes clip into the insulation then screed directly over the pipes.
For a single room it's got to be easier to use electric.

Electric ones very cost effective to run
No loss of heat into walls etc, rises naturally, will be using it on next house I do
Tile shop near me has demo rooms with it, remember you dont have to do where you wont have open floors (under units etc) if that helps

Surely hot water system is cheaper? Yeh I thought it needed raising which means a step would be needed which I didnt want

Mate has it in his house. No step.
Hot water will have more losses from burning the fuel to getting the water to the floor id have though.
Electric would be easier too.

You can get a 'wet' system that only raises the floor level by 18mm its by Polypipe and is called Overlay. Got to be cheaper than electric

we put it in every house we build/sell, usually only on the ground floor too.
we never use electric, always the pipes and water.
Most people don't know how to use underfloor heating properly and treat it like normal heating (i.e: feel cold, switch it on)
we recommend its left on all the time and doesn't need to be really hot, but our house also have solid oak floors, so the underfloor heating can warp that if used incorrectly.

Its designed to be used constantly at much lower temperatures that regular CH.
Where your rads normally run at 50 degrees+ the underfloor heating runs at about 25/30 degrees so your boiler doesn't have to work as hard/being cheaper to run

It runs cooler because it's fitted in super insulated houses. Would be useless in somewhere older with drafts everywhere.

Im thinking about re-doing my bathroom & fitting an electric system. Ive already bought tiles though, do you need to use a certain type of tile or is a Porcelain tile ok to use?
