I have just partially drained my system(closed the radiators) to move a radiator pipe. When i filled the system back up the radiator closest to combi boiler wont get hot but all the others upstairs and downstairs do. I could,nt turn off this radiator as return valve stuck(in open position)...

Apologies if this comes across as a simple question but I would like some advice please on how to go about balancing my heating system which I have just enlarged to cater for a new extension that I am building. The original heating system consisted of a Y plan setup with a single pump serving 9...

Hello, I did try a search before posting but couldn’t quite find what I was after. Since bleeding all of my radiators my bedroom radiator gets far too hot. It doesn’t have a TRV. The cap on the manual valve just rotates freely in either direction without making a difference. I can’t remove it...

Hey everyone. I read the FAQ article on how to balance radiators but I think I need to clarify whether it was necessary on my system. I want to run the system as efficiently as possible in my 2 bedroom 1930's end terrace. I have a gloworm 30cxi (30kw) condensing combo boiler connected to 6...

Hello, we're converting the garage and have added a new radiator. The radiator works but the other radiators downstairs and one on the landing are now not heating up. We've tried bleeding and balancing all the radiators which does not fix the issue. The existing main pipe is 15mm with 10mm...

Would appreciate some advice here. Symptoms and notes: 1. Almost all rads (except one small bedroom rad) have been replaced, 7/8 in total. The system was flushed (not power) and inhibitor added when rads replaced. Also boiler is only 1.5 year old. 2. One or two rads need bleeding once every...

This is a frustrating one! Radiators are spread over 3 floors, one on the ground which is right next to the boiler (Worcester Bosch Greenstar 30si), 4 rads and a towel rail on the second floor with one rad currently disconnected for (very slow!) decorating, then 2 rads and a towel rail in the...

I've just moved into a new house. All radiators work except 1 in the hall, and in the kitchen where the radiator had been removed. I've put a new radiator into the kitchen and it heated up nicely when it initally filled up but this has also now gone cold. I've tried balancing by switching off...

I recently had a vented indirect cylinder (fed by a tank in the loft) replaced by a unvented indirect one (fed by the mains). The plumber left me with a leaking pipe causing the pressure to drop, not a great start. As he never came back to fix the issue, I had to drain the system to replace the...

Let's say I were to go round my house balancing the heating system by adjusting each lockshield using the delta T ~12C method across all 14 rads. Now let's say I add a new radiator in. It won't be closest to the boiler but relatively close. Do I need to just adjust the new one to the required...

Hi, hope some of you gurus can help me. Background: Recently had a loft conversion where we added 3 radiators, 2 in the main room and 1 bathroom radiator in the en-suite. Boiler is a Glowworm energy saver 80, rated at 83,600 Btu/h Builders installed and added the plumbing and went...

Hi, Have been scouring the forum and have made some progress - but now I've got stuck! We have two radiators downstairs that barely heat up. If we turn off ALL the other radiators in the house, the 2 problem rads will get very hot, but the minute we turn the others back on - even at a very...

I have a leaking radiator. I have turned off both valves to stop water entering the radiator and am trying to drain it off. For some reason, though, water is still coming out (so far, a washing up bowl of it). The leak appears to be on the pipe between the balance valve and the radiator...

One of the radiators in my house has not worked for a long while. With the summer on its way out and winter approaching i thought i would have a go at fixing it. The central heating is all newly fitted (3 years old) with a worcester combi boiler. I find one of the inlet pipes is hot and...

I balanced my rads "by hand" and when starting up the heating today, I notice they are quite slow to warm up all over. I have a modulating boiler, and a modulating pump, amd TRVs on almost all of them (the one nearest the wall stat I have adjusted to be the slowest to warm up, it has no TRV)...

Hello all, I thought I would try balancing my radiators but am stuck at the first hurdle. Each rad has a TRV, as you would expect, but they don't have lockshields. When I unscrewed the cap on the 'other' valve it was identical to the TRV (pin and all). I have never seen or heard of this...

I hope somebody can advise. I have a 5 bed house with 13 radiators and a Vaillant Ecofit Pure 835 combi. 15mm pipe work. All radiators get very hot, except our main bedroom. The top half of the radiator is warm, the bottom cold. The lockshield pipe is cold, the TRV pipe is quite hot. Is this...

By balanced do you mean balance of the radiators or easier run for the water to head off to the radiators rather than the hot water? Radiators reasonably balanced and haven;t changed configuration of radiators for some time (added a small radiator a couple of years ago but didn't have this...

We've had new radiators and a heat pump fitted. It all works, but I'm trying to fine tune the radiator balancing and I'm struggling. There are 4 bedrooms on 1 thermostat upstairs. The thermostat is in the biggest bedroom. I've had to turn the lock shield valve down to 1/8 of one turn in this...
