Hi All,
We are building a passive slab which ties into a warm retaining wall. The footing for the retaining wall is 200mm thick and takes up about 60m2 out of 140m2 and I'm wondering about the UFH spacing on a slab in this area. I'm thinking 200mm, the same as everywhere else. Will I just be heating up the slab? Also I'm looking to clip the UFH in under the rebar, has anyone ever done this before and any advice.
If the zones are crossing two rooms can you run the UFH under a supporting wall?
Is there a way to calculate the heat output of an UFH circuit?
thanks again,
