radiator

Hi all All of my TRVs are very old looking and don’t seem to work properly, the temp is either hot or cold despite what number the TRV is set to. My original plan was to replace all of the TRVs but my understanding is that for the hassle of changing them all I might as well replace the rads as...

Hi all, I have a very basic heating system that I would like to upgrade. Basically, it consists of a Oil burner (non condenser) and two zone systems (downstairs and upstairs), plus hot water tank (which is part of the upstairs zone) There currently are no thermostats except what is on the...

I'm replacing boiler with an air source heat pump, and adding / replacing about half of the radiators in the house. The feed/return loop plumbing is all 22mm, but while old radiators are 10mm plumbing mostly off a couple brass manifolds, new rads are 15mm plumbing. Will mixing piping in this way...

One pic shows the experiments I'm doing with supporting a type 11 radiator (160cm wide, 50cm high, total weight around 35kg) using universal column radiator feet. The other pic shows the detail of the contact surface between the rad and the feet. Aesthetic considerations apart, is there...

I've just bought a new house and went to start the prep for painting one of the bedrooms. I took the radiator off to discover it was mouldy behind. I didn't realise it was lined with paper. Is there an easy way to fix this without having to re-paper the whole room? Suggestions would be greatly...

I need to hang a radiator (160cm wide, 50cm high, total weight around 35kg) via two brackets to a plasterboard wall. The wall is external, so that it has studs (about 12mm deep and 50mm wide) behind the plasterboard and then bricks behind the studs. I am lucky enough to have studs in...

What a good paint not peeling away with the heat for radiator copper pipe? i would need some white and maybe chrome for bathroom. Thanks

Hi, I have an internal, decorated plasterboard wall with poor studding: 120cm from its left end, there is a 22mm wide (i.e., as measured horizontally parallel to the wall) stud, then a 38mm stud (the two studs are spaced 60cm), then, after further 78cm, the jack stud of the door. I couldn't find...

Bathroom being replaced/rearranged. Washing machine going in bathroom corner via new spur in hall, with upward sloping hole up to new spur backbox. Is it ok to Wago a junction in a 16mm blanked off galvanised backbox, to run a switched fused suppy for the towel rad off to the left (1000 height...

Hi there, I have a radiator that was not properly fixed to the wall and is falling away. It is a cast iron, but not too tall. It has HB Signature Thermostatic TRV valve and lockend. I turned the TRV down to the frost symbol and using a screwdriver, turned off the lockend (assuming that a...

Hi, I have a standard radiator (1/2" female bsp) on which I'm installing a new lockshield/TRV kit. The lockshield is similar to this: What happens if I remove the nut and everything on its left in the pic, and screw the valve directly into the radiator (with PTFE)? This would simplify my...

Just moving into the ground floor apartment of a 7 storey building. The building has a central one pipe heating system. We needed to move one radiator but the problem is that it no longer heats up. The pipe going in is hot but the one leaving the radiator is cold. The radiator, valves etc are...

Hi, Over recent years, I've had to paint several of our cast radiators (previous owners had sadly not made the best of jobs). Used white radiator wet spray but found that the Hammerite paint provides a better and longer lasting result. Need to tackle two more radiators but this time we want...

I have to fix a radiator or towel rail radiator in a bathroom as the radiator is missing. The old connection has been left with only a twin entry valve. Can I install a normal double radiator ( 40 cm width) by connecting one end with the Twin entry valve and cap off the other side of the...

Hi, Our central heating system is now 20 years old and we are having the boiler replaced. At the moment we have bog standard white convector panel radiators that were put in when the original boiler was fitted. Some of them are looking a bit battered, have paint on them and chips in the enamel...

I've got an old cast iron panel radiator that I've recently had stripped and repainted. On piping up it has a weeping leak from the bleed screw at the top. Taking the screw out and cleaning up I could see the screw thread has a notch in it and the hole that it screws into also has notches in...

Hi. As the title says, I have a regular style radiator which constantly has a trickling sound while the heating is running, but each time I try to bleed it, no air comes from the bleed valve, just water. Curious to know people's suggestions on how to get the air out. Cheers

Hello all, new to this forum and looking for some advice (or if I should get someone in to do it) Looking to replace a single panel radiator with a Kudox type 22 double panel. The installation diagrams show the valves should be approx 85mm from the wall. The current lockshield is about half...

Hi there, I’m a complete novice when it comes to plumbing so bear with me please!! Basically we moved into a new build house and in March time we had a fireplace put in but had to move a radiator in our living room which was completed and no issues, heating worked fine....I think I only topped...
