UFH - copper pipe...what if.....

[bassmonster]

just out of curiosity, what if i used 22mm copper pipe for underfloor heating without a manifold? just zoned off to cover about 15sqm....

It's to go in my new kitchen extension. flooring will concrete 2 x 4" timber will be resting on the concrete. I was just thinking of notching into the timber....

thoughts?

Temp control of floor? Pump?

No additional pump and standard honeywell roomstat.

No additional pump? No blending valve? You're proposing to run UFH at radiator temps. The floor would be too hot to walk on until the stat shut the 2-port off then it'd get cold and repeat.

Silly idea.

i definitely wouldnt use copper plastic in continuous lengths is perfect for underfloor
if your looking for under floor to warm the room it has to be the full works but if you just want to take the cold feel of a tiled floor ive got a loop of ten mm routed into the ply under my tiles about 300 mm out from the units running with no controls which just takes the chill of the floor where you stand i could add a tmv if it was to hot but its been in 16 years no problems
you can buy single room kits with mo mixer that have a thermostatic trv with seperate sensor which goes onto the return which do seem to work

as Above this is what plastic pipe is designed for, and some of the underfloor kits specd by manufactures are relatively inexpensive

Thank you for the reply all.

any chance you can provide a link to a single room kit..

http://www.underfloorheatingsupply.co.uk/15m2-Valve-Underfloor-Heating-Kitthis is the only one i can find now but the two i fitted had a normal remote head trv on the flow and the remote sensor is taped on to the return
