Underfloor heating off C/H loop?

[P23UNK]

I'll try and explain this as best i can for everyone..... I'm trying to find out if it is possible to fit a very small amount or under floor heating to my bathroom when i renovate soon, aprox 9 square meters. I don't want to fit an additional programmer or a pumped manifold. I'm looking for a solution that will allow me to take a spur off the flow/return and use that to warm the floor. I'm thinking if both flow/return feeds into a tempering valve that will reduce the temperature leading to the U/F loop and the end of the loop can connect back into the return closer to the boiler. That way the U/F look will heat when the rest of the heating comes on and will not burn the soles off your feet. Can any one sugest a better/more suitable option or advise? Any help would be great. Cheers.

get a sparky to put down an eletric matting ufh system, then it will save us having to go through the pain of reading all the pros cons and wrongs of ufh detailed in a recent thread.see central heating forum homemade ufh, and you will have an idea of differing views, pros and cons.

Simple answer no

Go for electric as said

Danfos do a pack which just has a trv like head on a mixing valve which you come of the heating zone like if you were adding a rad, you fit it a bit like a shower valve in the wall. The one we fitted worked okish but i wouldnt recomend it. (we did also take pipes for a rad upto the window and left under screed incase it didn't work)

Electrics expensive.

and as lameplumber explained have a search, then buy a proper kit.

Cheers for all the advice, i'm swaying more towards the electric ufh mats now after looking further into it. Are they run from a timer or just an on/off switch? I'll google it. Thanks again!
Where is the damn thumbs up smiley? :thumb: ??

Definitely a timer if you go down that road.

My brother fitted this set up in his own house when we first started experimenting with Ufh.
Absolutely useless!

fitt eletic mats, the U/f heating would not have time to heat up if run off the exasting heating system
