Have been busy building a second hand conservatory and am now up to sorting the flooring out. I have built up so all I have left to do is 100mm celotex and then 75mm screed.
At this point I want to install underfloor heating pipes, The floor is 26.8m2 by my reckoning of 150mm centres I need 200m of pipe. I have read a couple of articles which say I cannot have pipe runs greater than 100m so would need to do 2 runs. Is this the case, how do I finish the ends into the garage in/in/out/out or in/out/in/out on water. what would the spacing be next to the manifold. I cannot afford manifold etc. at the moment but cannot see the point in not fitting the pipes at this stage.
All advice welcome.
