UFH

[dboden]

Hi, I am thinking of putting UFH down after we have fitted new kitchen.
Does anybody know, or have any experience,
is it expensive to run? we just want to take the chill off tiles.

Thanks

If you put down insulation boards first then they can cut the running cost of the ufh...with out them then it can be expensive to run....plus the insulation boards give you a faster heat up time........the average thickness for best results is 10mm to 12mm......

At CTD we work with Devi on underfloor heating it is electric and mat style.

Running cost are roughly 0.5p to 0.75p a square metre an hour.

If you would like more info i could contact your nearest CTD branch and get them to give you a ring??

Cheers.

What wattage is that Marie ?

If it's the concrete one mr T.......it will be 150w per sqr mtr......

The running cost of a cable or mat is dependant upon its rating/output and is based on the units of electricity consumed.

A unit of electricity is 1000watts (1KW) for 1hour at the unit cost of electricity
ie 1500w x Ihr x 6.5p/unit = 9.75p/hr.
operated on ‘off peak’ this would be 1500w x 1hr x 3p/unit =4.5p/hr

The devimat warm floor system costs approximately 0.5p per hour, per m2 to run.

Wetdec i'm finding out more information as we speak as soon as i know i will post it on here.

So... a 150w output will be cheaper to run than 200w?

It certainly would be.

100W/m2 even cheaper.

Remember that if you had 200w/m2 though your heat-up time would be reduced, therefore it wouldn't be on as much as a 100W/m2 system during that time.

With insulation I'd go for 100W/m for taking the chill off the tile.

Thanks you both for that.

Its a job to know when asked sometimes especially with the differing wattages.

Companies are recomending

100w for house
150 / 200w for conservatories

They are sufficient then ??

As a general rule of thumb I used to say 100W/m for wood and laminates, 150 for interior of the house, 200 for conservatories and out-buildings.
I'd recommend insulation with them all, but if you're not going for insulation then perhaps use the next heating output up from the one you were first thinking.
