    Hello. I am here for some advice please. We have a water underfloor heating system in our house and have recently had some issues with one of the zones seeming to overheat with the heat still being sent despite the thermostat not sending demand or even being on an all. These are all new...

    Underfloor Heating Pump goes into a blocked error (Grundfos UPM3)

    Hi all! Went to stick the underfloor heating on and the pump started making a weird noise and the first red LED and the last amber LED are on - which per instructions means that the pump is blocked and it is necessary to deblock the shaft. It has a deblocking screw in the centre of the control...

    Wet underfloor heating adding a rad.

    Hi there, just after some advice. I have an underfloor system installed and at the time of laying I had a spare loop put in with a view to adding a conservatory. I've now changed my mind and want instead to add in a single radiator. I can see the unbroken loop protruding into the conservatory...

    Underfloor heating

    Can I ask for advice, would it be ok to install underfloor heating as an additional zone on an existing s-plan circuit. The plan would be to have the thermostat for the room with the underfloor heating, operating the new zone valve, and at the same time switching the underfloor pump. Would it...

    Biocide for underfloor heating?

    How essential is biocide in UFH? I have brown dirt in nearly all flow-meters and heard different views on how effective biocide (such as X700) may be. Some say brown colour is from iron particles (magnaclean is fitted) other say its from bacteria living in the pipes? On a close topic: Is it ever...

    Dirty water in underfloor heating loops - how big a job to drain/clean them?

    Hi, I have been noticing my underfloor heating taking longer than usual to heat up. Decided to take a look at the manifold and noticed the water in all the loops looking a bit worse for wear: While not super urgent right now, I think I should get that sorted out in the near future. How big a...

    Underfloor heating - manifold valve leak

    My underfloor heating has sprung a leak where one of the pipes reaches the manifold. I have tried giving it a bit of a clean and tightening it, but to no avail. Every time I re-pressurise the system is goes again. Is it as simple as shutting off the water supply to the heating and replacing the...
