radiator

i have a question regarding a radiator swap but i think its already being discussed here when i post the thread it says "already being discussed" so how do i search the forum my issue instead of google?

I'm hoping someone can help me get my head around understanding radiator valve pressure drop. As an example, from the attached chart, a lower pressure drop results in a lower achievable flow rate. To my mind, a lower pressure drop (i.e. less resistance to flow) should give a higher flow rate...

You may ask why I would want such a thing. Our home central heating comes on at 4.30pm. But we don't need to heat the bedrooms until 9.30pm. that's 5 hours of wasted energy every day. If we could time the thermostatic valves to come on at 9.30 it would solve the problem. I know I could install a...

Hi All! My first post here.. I need some help from someone who really understands central heating systems, pipes and radiators. New boiler installed My 20 year old Ideal Mini boiler finally failed in December with no hot water and it was leaking all over the floor. It turned out it would be...

Hello, can anyone help me please? (apologies for the layman's terms in places, but I hope you can understand what I mean). We had a new radiator installed today by a reputable plumber, as the old one had slush and would no longer heat up. I'm told the existing pipework was also flushed out. It's...

I have noticed over the past few months my boiler pressure dropping a tiny amount of 0.1 bar but were unable to find any visible leaks. This seemed to coincide with drops in temperature, and after reading similar issues checked all radiator tails and noticed 3 are weeping in the same place on...

I have 1 cold radiator that is furthest away from the combi boiler. I have balanced the radiator so that the lockshield valve is all the way open, however no hot water coming through the TRV. When all the other radiators are off it barely gets warm. I thought it might have been an airlock so...

Hi, Our hallway radiator burst on Christmas Eve - it’s the second time it’s had a leak so I reckon, as it’s from the 70’s, it’s time for a new one. I’ve fitted radiators before and done bits of plumbing so I reckon I can do it. The wife wants a smaller radiator but a double so we get the same...

We’re recently moved in to a new house, and we have quite a mixture of radiator configurations. What’s this setup? 2 feeds on the left and lockshield in the right. Is there a reason to setup this way? Haven’t come across it before. I’m assuming 1 flow and 2 return.

I am buying a flat at the moment and all the radiators have just one inlet where the 2 pipes enter. Is this a twin entry valve? Ideally I would like to renew the radiators so would like to know if I can swap them for new radiators and re route the pipes to either side with standard inlet and...

Hello, we have a radiator in our living room and would like to add a second. The photo shows the piping going into and coming out of the radiator. From feeling the order that the pipes heat up I think I’ve figured out the direction of flow which I’ve marked with red arrows. Would this pipe...

I'm looking at replacing a normal rad with a towel radiator. The pipes (15mm copper) come horizontally out of the wall and are 580mm apart (centre to centre). Putting in 500mm towel radiator (450mm to 470mm pipe separation) looks easy (90 degree elbow horizontal to angled rad valve). One i...

I'm looking to add a radiator to my living room. I've included below a plan of the living room showing the existing pipework (solid lines) and proposed new pipework (dotted lines) which all run under the floorboards. Boiler is more than capable of coping with this new radiator. Question is...

In the linked photos you can see two radiators, one with a static valve and the other a TRV (with head removed). I need to swap the two valves. The third photo is the lock shield at the bottom of each rad. What are the correct steps to swap these two joints without hopefully having to flush an...

How to plumb a heated towel rail to these pipes?

I'm planning on relocating the pipes for radiators 1 & 2 to make way for a steel beam. Radiators 1 & 2 will branch off the main flow and return between radiators 3 & 4. I noticed the flow & return leave the boiler in 22mm copper and steps down to 15mm copper before the first radiator, this then...

Hi All, I appreciate there are numerous similar posts but I'm look for clarification to judge whether I should try to replace radiator or have a plumber come out. I have an Ideal Logic Heat 12 boiler and Tribune HE cylinder, circuit for hot water and 2 circuits for heating as I understand it...

Hi, I’ve ordered a new radiator and the lower connections where the pipes would normally connect are sealed up in a way that looks welded. The product photo online clearly shows the radiator connected to pipes at the bottom but I can’t see how this radiator could be used without being connected...

Good afternoon all, I am soon to have a new combi boiler fitted to provide central heating and hot water (currently just have an old hot water boiler). I am in the process of fitting my central heating system pipe work, and I am hoping for some advice. I have drawn up a picture below of what...

Hi all, recently replaced all of our normal trvs to smart trvs, except one radiator to allow it to always flow if the others shut off. I am experiencing an issue on all radiators when one of the TRVs hits temp and closes the valve, there is a tapping noise on the exit pipe of that specific...
