radiator problem

I have a radiator in my lounge that refuses to get hot. The infeed pipe is getting hot so I know there's water there waiting to get in it. Ive tried the following: Replaced TRV and also tried it with a matching one in the house that I know works and this doesn't help. I've confirmed movement...

Hi, had a job where living room rad not getting hot. Flow pipe red hot return cold no heat in rad. Tried shutting all other rads off to get heat still the same and rad starts to get very little heat but still not returning. Replaced rad and valves still the same issue. Took off rad valve and...

Hi, we moved into a 1960s house just under a year ago and this has been out first winter which has been very cold. We are currently getting the old wooden framed windows and porch replaced for new uPVC ones. There is only 1 radiator which is in the bathroom that gets hot which is a new one that...

Just installed 2 new column radiators in my lounge - replaced old radiators which worked fine. I’ve installed similar rads before without issues. Radiator is stone cold but one valve is very hot (other valve is cold). Other radiators in the house are hot as normal. I have a combi boiler with...

New Member Had a new radiator installed replacing the old one in the shower room. Plumber couldn’t get the exact size as it was that old so went slightly bigger, wasn’t told about it (Previous 480x600 and New 500x600). Wasn’t aware until he came to fit that the connector sat right up against...

Hi, I had a Worchester Greenstar 30Si compact boiler installed approx 6 years ago. New pipe work and radiators installed at the same time. I had noticed the radiators didn't get piping hot and the flat took longer than expected to heat up, I was told its just the way the system works, old flat...

Hi all, I've just moved into this house and the living room radiator isn't heating up. I've searched through the internet with a lot of guides but it seems (at least in my unexperienced opinion) that my problem is a little unique. So, this living room radiator doesn't have a TRV - both sides...

Hello all. I have a, hopefully common, radiator issue with a hopefully simple fix. One rad heats up only when it feels like it - less than 50% of the time. F&E system. 2 bedroom house. Standard boiler (not combi). Grundfos alpha 2 pump. Hot water cylinder. All chemicals in system replaced 2...

I moved into a new-build property a week ago and during the walk around by the site manager was told that the main radiator in the hallway can't be turned off as it controls the thermostat. The issue I'm having is that the house is far too hot. None of the other downstairs radiators even come on...

Initially both central heating AND hot water stopped working completely. Through various small fixes, I’ve got the hot water back working, and a small amount of central heating. The system is: Indirect open vented F and E gravity system. Back boiler behind fireplace. Two tanks in loft (header...

Hello everyone wanted some advice on our Central heating system in our flat in Berlin we brought 3 years ago...we inherited the system from the previous owners which are... Junkers boiler Ceranorm and thermosta (set to come on 6am-11pm at 21C) Grundfos pump on timer (set to come on three times...

I have a large system. 15 years old. 16 rads plus a towel rail. Was a brand new instal at the time. I have 1 room which is close to the boiler strangely however the rads just don’t heat up. They will if I switch off all other rads via lock shield or trv but pretty much in all other circumstance...

I am in a student accommodation and the radiator in my room when it is off continues to make a loud sound of air and metal (See attached video with headphones). The technicians tried to change a small valve on the right but that didn't work. Can you tell me what the problem is? Many thanks...

Hi all, The radiators downstairs are working fine but the radiators upstairs are not heating up at all. I have checked to see if the pins on any of the radiator valves are stuck and they are not. I have also bled the radiators and this is not the problem. I would be very grateful for any...

Hi, Having problems with these rad valves. The chrome type fitted to acova column radiators in a renovation project. Ex-plumber here but been out the game for 15 years. Basically, they ‘work’ when heating starts from cold but then trv shuts off and never cuts back in. So for example - heating...

Hello! Recently, the TRV fitted to one of my radiators has started to make a tapping sound when the heating comes on. This is not a hammer, as it is far slower going between maybe once every 2 seconds down to every 5. The sound seemed to be coming from the valve itself, or the inflow pipe. The...

Hi folks, I am looking for some advice on my Central heating. I have recently moved into a 1930s semi with an open vented system and 11 rads. Some of the downstairs rads were heating only partially or not at all, so I drained the system and put some cleaner into the central heating feed tank...

Hi, I’ve recently purchased a new build property. There’s a combo boiler downstairs in the kitchen, and in the main bedroom there’s one radiator, and in the en-suite there’s another. Neither of them have ever got hot, or even warmed up. They’re always stone cold. There’s two thermostats in the...

Hi, we have been having issues with our boiler, it keeps firing up and it shows that it is heating the water. the radiators are constantly 'luke warm' and we haven't even turned the boiler on. Any ideas of what I can do to stop this as it's now costing us money for not using the boiler! Thanks :)

Our central heating system works separately over two floors (Individual thermostats), we have 12 radiators (6 on each floor) including 1 radiator without TRVs on each floor, one in the master bedroom and one in the lounge. My confusion is this... When either heating system is on, the radiator...
