  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!

    Further to my letter, I was contacted by Ben Perris. Ben asked me to carry out some checks on the two actuators, which were a bit delayed because the weather was too warm to have the heating on. However Ben then sent me two replacement actuators, which I fitted as soon as I was able to.

    I have now had the ABAs in use for over two and a half weeks and I am pleased with the way they are operating.

    Please pass on my thanks to Ben Perris for his prompt attention!
