Hi
I've read the key post regarding ufh and it has helped me a lot with specifing the system. I'm building a new sunroom 14m2. The plan is to put electric ufh under the tiles, but also have a large radiator. The electric ufh will act as a means to heat the tiled floor. The idea would be to run the electric ufh from the night time meter and use the radiator as a means of heating the room if required during the evenings.
The question I'm unsure of is should insulation be placed between the electrical heating and the concrete floor OR should it be left without insulation ? (The slab floor will have insulation under the concrete, as per normal building stds.)
If no isulation is placed, then the concrete slab will emit the heat in a slow fashion (like a storage heater) and suit the use of night time electricity. However if insulation is placed, then the slab may not act as a storage heater, making it unsuitable for the cheaper night rate electricty, however have the advantage of better heat control that suits Irish weather.
Has anyone have similar system installed and could comment ?
Thanks
