  1. Dave Wood

    Fixed our 4 loop kitchen diner underfloor heating floor temperature problem. Same temperature over all the loops unlike before where one was hot 2 were ok and 1 was cold. Great
    UFH engineer amazed never seen them before, said if they work best thing ever.
    Yes they work

    My nineteen zone, good underfloor heating system has been transformed into one which is now brilliant- no cold spots ever, and very even, controlled heat. I wish that these had been available seven years ago!
