    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.

    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...

    Hello all, I’m looking for some advice on my Vaillant boiler, which is controlled by my Hive thermostat. I have set the radiator flow temperature to 75 degrees on the boiler control panel, but the actual temperature never gets hotter than 50. I have done some checks, and believe I have found...

    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. After an hour or so, I circled the house looking for issues, and found one. The radiator in the kitchen was not "hot" like the others. I'd seen this before, and...

    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!

    New radiator install, adding tails and on tightening, I heard a crack!

    Hi, I'm installing a new radiator and just getting round to adding the tails. The one with the heat control went on ok but the other made a single crack on tightening up the tail.

    Considering buying the Tado Smart Thermostat and valves. My upstairs radiators are older and I'm unsure if the valves will be compatible. Has anyone had any experience of installing Tado Smart Valves. Do you know how to determine if they'll fit?
