A few more images showing the completed UFH network for upstairs, the servicing battens downstairs and also some additional "supports" to accommodate the fitted kitchen units. I have really been impressed with the UFH fitter - he has even supplied photos of vulnerable positions so there should be no excuse for puncturing a pipe after the screed and boarding has gone down. You will see the areas left "unpiped" in the en-suite and bathroom areas. The manifold is stored in the landing cupboard
