NEEDED - Underfloor Heating Engineer

[DavidPeckham]

Hi there, I really need some help, I'm half way through a two year rental and the underfloor heating has a life of it's own, I've got two sets (Kitchen and Bathroom) with different makes of Thermostat/controller and neither follow the timings I've set and at times go all the way to 27 in the afternoon when noramlly no ones home. I've tried calling the makers, using the YouTube videos and getting in touch with the original installer, and now just need to find someone who can come and sort it out, please send help, recommendations or ideas, I can't take another cold day with the windows open for the sake of environment, bills and sanity!
