I have a problem balancing a towel radiator in our system in that I can't seem to get any temperature drop across the flow and return. It has a valve on each side but no matter what adjustment I make, I seem to only ever get the rad to be either completely off or scorching. Any advice...

Having had a new boiler installed and looked up the information on balancing the radiators in the house could somebody explain to a beginner why you balance them up with all thermostatic valves on max? i.e. My Westherm on position 5. I understand the balancing of the system for the required...

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, I have two of these Towel Radiator valves (different bathrooms) and I cannot figure out how to balance them. They seem to be either on or off, I guess I could leave them diagonally turned on, but that somewhat ruins the square effect and they are also very light and easy to turn so I know...

I always have heat output problems with one radiator in the house (loft bedroom but loft bathroom is fine). I've bled all the radiators in the house and even made sure that both sides of the valves in the bedroom are fully open. The radiator is hot on some days and not others. I'm guessing it...

Sorry about this but I cannot seem to find an answer anywhere - what is meant by the term "a balance rad"? which I have seen used bur not explained. It seems to be a radiator on the system with no TRV on it but for what purpose? Secondly, should you try to include it in balancing or should the...

I have 7 radiators running off a 30KW combi in an average sized end terrace. The biggest one is 5000 BTUs.The rest are much smaller. The pipework runs in 22mm from the boiler for about 3M before dropping down to 15mm for the rest of the system. I have one or two radiators which dont seem to...

Got Normal TRV4 radiator valves but wondering if the auto balancing are worth a change to? I've not got system balanced Or better just keeping the normal TRV4 and balance the system? Also, do they fit onto the body of the TRV4 body or is it a complete valve change?

I'm trying to balance my central heating, but all the guides assume the each radiator has a TRV at one end and a LSV at the other. In my case all rads have 2 LSVs. Should I leave the flow side fully open and adjust the return side in order to balance? Is it corrct to assume the the hotter...

I'm trying to get my head around the principle of the lockshield valve when balancing radiators. All of the research and googling seems to imply that this valve controls the amount of water returning into the system, but in order to control this it suggests that those nearest the boiler...

Hi A quick question. Formerly we had 2x downstairs radiators (one in hall, one in front room) fed by 8mm microbore from the same 15mm feeder / return (i.e. 15mm feeder -> 2 x 8mm microbore -> 2x radiators -> 2x 8mm return -> 15mm return). We've removed one of these radiators, and the other has...

I’ve had a new boiler put in (ideal 24w max +) and replaced all my radiators (5 in total - 2 bed terraced house) In my kitchen I have put in a 1800 x 600 double panel radiator The only way I can get it hot all over is to turn off every other radiator and blast water through this one. I...

The radiator in our hallway sometimes does not heat up but if i turn off all the other radiators downstairs the hall radiator heats up, so i spoke to the plumber about it and he told me that all the radiators need to be balanced and it could be a long process so you could do it yourself and save...

can a ch system be balanced if the radiators had the trvs and lockshield valves on the wrong pipes? the trv and lsvs are bidirectional (flow both ways)? thanks

In an existing system, how do you identify the sequence of flow through the radiators?

I’m familiar with the concept and ways to balance a radiator system so I’m trying to apply the same logic to my UFH system. One quick questions... should I balance the return 22mm valve that is attached to the bottom of the manifold? Leaving it wide open seems silly as the pressure is just...

Hi there, Can anyone give me any advice how to balance rads. I have a few rads in the house that get hot and the rest only get warm at best. Do I do anything different to the rads nearest the boiler. I'd appreciate any advice you can give. Pete

Hi I've bought a Smiths HL1000 fan assisted radiator to fit into the kitchen. The combi boiler is also in the kitchen and the 22mm flow and return pipes are right there to tee off. The radiator has 15mm stub pipes in & out. It's like a plinth heater but goes up high on the wall. There's two...

I need some help, having real difficulty balancing my radiators. Got modern slim rads upstairs, columns downstairs. Downstairs the rads are all on the right way. Upstairs, TRVs and lock shields are mostly on the wrong way. I understand they are bidirectional, but when trying to balance the...

I have just moved into a new house, switched the central heating on and it not working properly. Radiators We have 7 upstairs radiators and 9 radiators downstairs. All radiators are fitted with TRV and Lockshield valves We have underfloor heating one additional room Boiler Boiler is...
