Water UFH

[jassdhali]

Guys,

Looking at water UFH system, the one I am looking at suggests pipe centres at 250mm. I am installing in a kitchen approx 17m2.
I have read posts suggesting 150mm centres & 100mm centres.
Your guidance & experience would be gladly received.
Thanks

the closer the piping the lower the temperature you can run it..

Depending on floor construction & floor finish.

Guys,
Floor is 100mm concrete slab, at least 85mm celotex finished with screed.
Thinking about going for 150mm centres.
Does that sound reasonable?
Thanks

Without knowing your boiler, heatloss or system mate, I'd go for the 100mm centres. Regardless, the floor can be run at a lower temperature as long as it heats the room.

Thanks for your input Delta, But I actually ordered the pipework for 150mm centres just before you posted.
Went with this http://www.theunderfloorheatingstor...ing-standard-room-kit-to-cover-25m2-905-p.asp with a digital timer.
My boiler is WB 37cdi.
Will let you know how warm the kitchen gets in about a month
