[Closed] STW plumbing/heating engineer collective - underfloor heating advice required

smogmonster · 2011-11-24T21:32:17Z

Folks, the benefit of your collective wisdom please. Our underfloor heating doesnt seem to playing ball at the moment. It heats the downstairs (obviously), but seems to be heating only our guest room and ensuite, at the far end of the house. Our lounge, kitchen and utility are not heating at all, the floor remains cold. Thermostats are set to 20C..it doesnt make any difference where we set them, nothing changes. The boiler is a Combi, with the settings for the heating at 6 (out of 9 settings) and again, it doesnt appear to matter where its set at, the above areas remain cold. Hot water is being produced without issue. Ive had advice from a mate of a mate that underfloor needs leaving on permanently to work, which sounds like bollocks to me, is this correct? The thought of it blasting away from now until kingdom come fills my bank account with horror. As we are in and out at various times, we have it set to turn on and off at the usual times (0600 - 0900, 1100 - 1400, 1700 - 2230). Anyone help us out, either professionals, or anyone with a similar problem resolved?

Good u/floor systems will only call for heat when the water temp is demanding heat, therefore pump only comes on with demand.

Also better systems use variable speed pumps, usually Alpha + on them.
