Underfloor heating.

[enduro]

Electric underfloor heating, who has it and how expensive is it to run if laid with insulation board etc? Going to re-tile the kitchen next year and the wife wants ufh. Just wondering if it is expensive it is i will buy her some insulated slippers for xmas..:lol:

i havent got it myself and I guess it would depend on the size of room to the running costs. Customers who I have fitted UFH for in the past have said they wouldnt be without it now, so I guess they feel its worth while.
No one has ever said its expensive to run.

I dont have it myself but I have always been under the impression that it is quite cheap to run. I would give the UFH company a bell, they should be able to tell you... I hope.

Fair point...

A friend of mine has it, and never puts it on, because it's so expensive! I can't say how it was fitted though, so difficult to say!?!?! Every customer i've fitted it for seem to love it, and have never said anything about the cost. Piped will be cheaper to run, but obviously cost more to begin with, so really depends how long you're gonna be in that house hehe!

i know several people who have electric systems like those you get from topps and b&q and the like. They are expensive to run as a retro fit or as a primary heat source and need to be designed properly. e.g. 10mm of insulation boad is not likley to offer a great deal of thermal resistance to the subfloor so you end up heating the sub floor as well. \i know quite a few people who dont turn them on because of the running costs.

on the other hand i know of several thousands of square meters of apartments that have electric UFH as their primary heat source but these will generally be on top of 65 or 75mm of cellotex typ insulation so the heating does not use the subfloor as a thermal sink.

I looked at thee for my conservatory but opted not to cos they would rack up my leccy bill by about 20%.......

Are they not 150watts per sq mtr?

I have fitted it in all of my bathrooms, and the kitchen. It is not expensive to run (I use it as secondary heat source/ tile warmer) and keep it to peak times of the day. I would not be without it now.

I use mine as "tile warming" rather than a primary heat source. The bathroom mat is on 24 hours per day and I have never felt that it is a significant cost centre.

To answer your question a bit better Andy...... my place is a bungalow on concrete slab (1960's build one half, and new slab on the other half). I have only fitted the 10mm insulation boards and have no warm up problems at all or any issues of any sort. Do it mate, you wont regret it!
