UFH - Costs

[kevg]

I know UFH is not that expensive to lay, but I have a couple of questions on it.

What is the actual running costs on a daily average and how long does it actually take for the tiles to become warm ?

Thanks.

The tiles will become warm depending on the insulation below the UFH.
This was sent to me by a cement tile backer board manufacturer

Unfortunately thermal values are a minefield because there are differing standards, as here, and different ways of measuring them. However, in real life comparisons with cable underfloor heating the following approximate results were observed:

1. Onto bare concrete slab – took about 3 hours to reach max temp of 24°C.
2. Onto No More Ply 6mm – took about 40 minutes to reach 24°C and 3 hours to reach max temp of 27°C.
3. Onto Beavaboard 6mm – took about 30 minutes to reach 24°C; temperature 29°C at 3 hours and still increasing.

If you are going to use No More Ply under wire underfloor heating, you must remember to prime the surface with Mega® SBR as this helps to reflect the heat back up.

In summary No More Ply reduces warm-up time, increases efficiency and allows a greater maximum temperature. Beavaboard is cement-coated foam board of the same type as recommended by underfloor heating companies, and has the same effect but to a greater extent.

Therefore using an insulation board will reduce warm up times and also reduce running costs.

Thanks Sir Ramic, do you have any idea of how much it would cost to run ? Say.. using NMP for the 40 mins ? If you did that daily, would it be expensive ?

thread moved to correct forum.

I am sure that if you contacted our sponsor Uheat that they would give a far better answer than I could.
They are very friendly and only a phone call away.

a bottle of stella a day i think

Mum and dad worked there's out to cost approximately 7£ a week.

That was a 12mtr mat btw from uheat

that's quite expensive just to keep your feet warm but if it's a source of heat for the room too i guess its not bad
