Well the extension build on the house has started, in a conversation with the Mrs, she has asked about underfloor heating in the kitchen and dinning room as we have never had this in any of our houses I was as a loss to answer if its a good idea or not

Have any of you guys rate underfloor heating or is it not worth the agro in fitting, and cost of it running it cheaper than normal radiators? Our kitchen will be 5.6 x 4.5 metres, dinning room similar size, not small but not too big either. If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!

It's fab. I'd always go for it now if I can.  Graham

good if you have concrete floors, doesn't work well on wooden floors. Not good if you have carpet on top of it either, but makes a tile floor toasty 56 TDV8 Vogue SE

We have it in our bathroom and love it.  Si. <This is my name.

Dependig on your heater, floor insulation and topfloor it is very comfy. You do need a stone or tile floor though. If you're thinking of a wooden topfloor it's no use.

I have a wooden floor Robert, and many others do. It does work, although as wood is quite a good insulator, it doesn't work any where near as well as stone. You also have to choose your wood carefully. It is nice to walk barefoot on a heated stone floor though - as my bathroom is, and as I will finish my basement.

I put it in the conservatory on a well insulated base. ( polystyrene and turkey tinfoil to reflect heat)
I heat mine using the return leg of the central heating and its always comfy in there without any additional heat.
As the chaps have said floor finish affect the results I have laminate. It can be slow to warm from cold as you are creating a thermal mass but when up and running much better than radiators and a lot easier to install during the build.
The electric version is good but expensive to run Mine was a blue one!

put it this way, i build quite a few houses and have never used it and with sap compliance on new builds UF heating makes meeting the TER/DER very difficult. Which in layman's terms means though on the face of it it would seem quite an efficient way to heat the space, the actual energy use calks for it shows it to be inefficient, at least in the houses we build. I'm not sure why this is, but iirc the calks are moving away from thermal mass being a good thing, and a lot of energy goes into heating the screed (high thermal mass) that the pipes are bedded in before you get a useable amount of heat out.

it is however nice and toasty on the feet. There is nothing that can't be fixed with a hammer😜😜

If this was installed how deep would the floor need to be dug out to keep a level surface running though a house? I fancy it in the kitchen but think the ballache of digging out the old floor to lay insulation and new screed would make standard rads the way to go. I know electric is quick and easy but need a weekly lotto win to run the stuff. [img]http://www.fuelly.com/driver/rob2529/range-rover[img/]

If something can't be fixed with a hammer....... You have yourself an electrical fault!

i reckon you should need to go down, 50mm for the screed, 75mm for the insulation (minimum, wouldn't comply with new regs) and 100mm for a new ground bearing slab more if you need new hardcore sub base. so 9inches min below finished floor if the sub base is ok. There is nothing that can't be fixed with a hammer😜😜

I have used it in a couple of houses the current one mix of air heat pump and ground heat pump driven by solar panel assist so not too expensive to run

Cheers guys , looks like that's the way forward to heating the kitchen and dinning room

No wood floors in kitchen or dinning room so happy days  If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.
