I have been strongly advised by my (trusted, reliable and experienced) plumber against underfloor heating. A number of friends also advise against it and say they have had endless problems with their UFH, requiring floors to be repeatedly taken up.
We are renovating a 1960s bungalow and had hoped to use UFH in what will be the very large kitchen/diner – so many people in the Homebuilding Magazine articles seem to use it with no mention of problems. Any unbiased advice would be appreciated as I love the obvious no-need-for-radiators advantage but dread the thought of endless flooring nightmares!?
