I have installed a three zone system - simple question, I know how to balance the system, but not sure whether I should do each zone seperately, or the entire system with all zones fully on? I also need a hint about balancing DHW - I have a fourth valve which supplies DHW, via 22mm - clearly...

We have a megaflow cylinder and boiler on the ground floor and have recently had new thermostatic valves fitted on all radiators (apart from the towel rail), radiators balanced, system drained and inhibitor put through. For the first couple of days all was well but we've noticed a bubbling...

...loudly "clicks" (noise similar to the pipework warming up / expanding). I read recently (a link on this site somewhere) about "balancing radiators". I can see why this might be done and can also see this might be a cause of the noise, but the link does not explain what happens if a rad isn't...

I have balanced all the radiators but can not get a 20 deg temperature between flow & return at the boiler end. What do I need to do? Someone told me I have to back the boiler up but how do I do that?

Hi - I've got pumped hot water in my CH system. At the outlet end of the HW coil thru the cylinder there's a cheap cannonball-type valve which I doubt functions anymore. Am I right in thinking this was intended purely to isolate the pipework and not for any balancing purpose?? Am I right in...

Hello :mrgreen: i'm currently trying to balance my radiators having replaced them all during this years renovations, but am having a little trouble i hope someone can help with :?: I have replaced the old single slab rads with shiney new Kudox type 22s and fitted some TRVs. The...

Recently flushed out central heating system(combi boiler)when refilled, 4 radiators out of 12 don't heat up properly or not at all.Have bled these radiators and even replaced TRV on one of them.NO difference. Some one mentioned the expression "balancing the system".Can you help?

I've just had my loft converted. There are 4 radiators - 3 work, one doesn't - the plumber has changed the pump, balanced the radiators and bleed the system - still the one one in the bathroom refuses to get hot - any ideas?? Ta

...I believe that the temperature drop across the system should be 20 degrees but most of the stuff I have read seems to refer to balancing radiators with a temperature drop of 11 deg. I think this is to do with older versus condensing boilers but from some of the posts here I have read I...

I have tried balancing the radiators in our 400 year old cottage without success. When our bedroom radiator is hot, the one in the hall downstairs is cold and vice versa. It seems I can have one or the other hot, but not both together. Is there anything I can do about it ?

From a suggestion in my previous thread, I'm planning to balance my central heating system in the near future. I've read the FAQ here, and thought I'd get an IR thermometer to make life easier, but it seems some require areas larger than a pipe to take the temperature from. Can anyone...

I have tried to balance system by turning all lock shield valves down and openning one by one till they individually get fully hot. however as soon as i get to the 4th or so radiator the rest go luke warm/ or in the case of the downstairs shower room-stone cold i have tried this process...

Our new house is full of delights. One of them is the fact that the radiators on the back wall of the house work perfectly, but those at the front barely get warm. Perhaps the geography is just coincidence. 1) I assume the problem is due to sludge, but why would sludge build up in some...

Hi, Anybody got any idea why one radiator won't heat up. Have balanced, no joy. only thing i can think of is that I have changed the radiator for a finned convection type and kept the single in / out valve .(not thermostatic) Both in / out pipes are hot, radiator ...cold The piece of pipe...

Problem seems to be that the upstairs and downstairs hallway radiators get really hot quick while the others seem to stay either lukewarm or barely warm at all. Bled all the radiators but I’m suspecting a balancing issue. House is 2008 built so not old. I don’t appear to have regular lock...

Hi, Looking for a decent, and cheap, way of measuring the temp in my rad's for balancing the system. Has anyone tried this : http://www.maplin.co.uk/Module.aspx?ModuleNo=220790 Or, do you have a recommendation of what to use?

Hi, I tried to balance the raditators in the house that we're renting. The system is an old hot water tank system heated by an oil boiler. The valves are lockshield valves and wheelheads at either end. The upstairs radiators are closest to the hot water tank. Essentially I want the downstairs...

Help. I think i need to try and balance my radiators but none of the valves have covers on them. They are all quite warm ( possibly too warm ) except the front room which doesnt seem as hot as it could be, i've bled them all. Its an old 2 up 2 down terraced house and is crap at keeping heat...

Can anyone explain, in layman's terms, the principles of balancing domestic radiators ? My understanding is that the valves either end of individual radiators are for this purpose, but when following the procedure described on various internet tutorials I've come to the conclusion that my...

in a previous thread which i cannot locate I was being helped with radiators that don't hear up properly upstairs. I was advised to call in a heating pro which I have now done. He came out today and attempted to balance my system. The system is a British Gas 330 boiler, range rated to 24kw. The...
