    Thermostatic radiator valve lets water through at 0

    Hi everyone. Apologies - I'm new, but I promise to try and be an active member of the forum :) We're doing some decorating just now and it was suggested that we take off the radiators to make it easier for the plasterer. We decided to have a go ourselves rather than getting someone in for...

    Vertical radiator issues

    Hi Just installed a vertical rad from plumbworld with a bi directional TRV which was installed on the return. The Trv seems to not do much so I queried it with plumbworld. They stated the Trv must be on the inlet side regardless of it being bidirectional. Is this correct? What was the point...

    Loose metal particles/ shot in brand new radiator?

    I've just unpacked a new column radiator I bought online to fit it. On moving it around there was a rattling sound so I took a cap off and upended it and poured out a small pile of metal shot. Is this normal? I've fitted radiators before and never noticed this. I can vacuum it out but concerned...

    Additional radiator not warm

    Hi all I’ve got a radiator in our conservatory which appears to have been piggybacked off the plumbing from the living room rad on the floor directly above it. It was like this when we moved in, I know it’s not building regs but oh well. The problem is it’s the only one not getting hot since...

    Isolated radiator need pump?

    If a radiator is isolated at the end of a run, like a spur on the system ie the feed doesn't go on to another rad, but is sent back to a rad earlier in the run, is a pump needed to near the rad to push the water through more efficiently at this extreme end? At the moment the rad doesn't get...

    Cold Radiator - questions regarding valves

    Hi all, I'm hoping someone here can help. The radiators in my living room aren't heating as well as the radiator in bedroom, hall and bathroom in my flat. I've checked and both seem to be free from trapped air (tried to bleed and water came straight out). Now one radiator gets a lot warmer...

    A reluctant radiator

    The "boiler" in our house is upstairs. When the weather turned cold again, I switched it from hot water only to heating and hot water.

    Moved in to bungalow recently and 1 radiator is cold. All the others get really hot when turned on. Gas system boiler, header tank in loft. I tried balancing, turning off other radiators, increasing pump speed, but best I could get at high pump speed is a tiny bit of heat in radiator, barely...

    Swapping a manual radiator valve for thermostatic.

    Hi, I hope this is the correct place to ask this. I've been given a bunch of smart TRV's to put on my radiators at home. Mostly they've gone on fine (to these valves) but 2 of my radiators have the manual valves shown in this image: My question is, can I just remove that core and...

    Thermostat (manual, M30x1.5) does not fit on radiator (too large)

    Hi, I bought a M30x1.5 thermostat and was hoping to fit it onto the radiator (there is currently no thermostat attached), but it does not fit (the thermostat connector is too wide, see photos). Do I need an adapter or something, or a different thermostat? Thanks!
