New kitchen/diner extension has wet ufh. Completed just before Christmas, but the thermostat controller didn't appear to be working properly - builder thought electrician had muddled the wires as room temp would say 27c when it clearly wasn't! We could control the heating though.
Last week electrician came back to tie up a few things and tried to sort it out. He thought he had....however now the room does not seem to warm up. Builder came back and said it was the controller. He sorted out time settings and said it works now. However it doesn't. Since 3pm its target temp is 23c. At the moment room temp says 20c and floor temp says 20c. I have another thermometer in here and it's saying 18.5c.
Builder is coming back, but he thinks we're just been stupid. I've not had ufh before and he says it takes time to heat up, but surely after 4 hours it should have reached the right temperature.
