A great day today was seeing the underfloor heating (UFH) pipes installed and laid onto the Celotex. We went for a aluminium core UFH pipe (Multi layer composite Pert-Alu-Pert WRAS approved) to provide additional strength than just the Pert only pipes. In fact we opted for Wundapipe!
It has been fixed to the floor using a combination of staples and tracks to help achieve the desired spacing to provide the right amount of heat output.
We had a great installer who established the required pipe-centres based on the predicted heat loss/requirements of the room. These varied from 150-200mm centres.
Tomorrow the UFH manifold is installed and the pipes pressure tested to ensure no leakages. This is not likely as the coils are a continuous loop with no joins. We have used 6 coils to provide us with 4 different underfloor heating zones. Each zone will be controlled separately using a digital programmeable thermostat giving us a great deal of control over the heating needs of the house.
We are having radiators upstairs and in the existing kitchen/future lounge.
This sounds like a very dull post!! Sorry but we thought long and hard about the UFH and is by far and away the most extensive alteration to The Farm as we have had to start from the earth beneath the house and reconstruct the foundations, sub floor, insulation and now UFH. This will be covered with a sand and cement screed, which we will seal and paint with garage floor paint. The we need to save up for the final floor…

when you lay your screed be carefull of cracking in the door openings as this point is the weakest poin of the screeding.
it happened to me and it even cracked the limestone tiles i put down on top of the screed.
i would leave you covering of the screed for at least 3 months so you can easily rectify any cracking

Hi Andrew,
Yes, ours cracked as well! We were lucky that we are still living on the screed, well we sealed it with PVA and dotted bits of off-cut carpets around. Your advise is very sound, and I think in hind sight there should have been some physical expansion joints to combat this.
How did you fix your tiles?
Cheers, Nigel
