Plumbing advice- balancing radiators

Hi all,


I just wondered if anyone had experience of getting a plumber to balance a system?


We recently had some new radiators installed and since then, our heating has been all over the shop. We've tried bleeding the rads, fiddling with all the TRV's throughout the house but we still have radiators that heat up some days, and other don't. We also have weird banging and clanking at times which indicates air is in the system, but when we bleed the rads, nothing comes out.

Have tried numerous times to get the plumber back out to look at it but all we get is 'it's trial and error to get the system balanced- just keep trying'. After 6 weeks of trying it's still not right so just wondering if a) anyone has any experience of a plumber balancing their system properly and b) any recommendations! Most don't seem to want to do the job...


Thanks in advance.

It's one of the those jobs that isn't too difficult but can take a little time.

The basic principle of balancing the radiators is to maximise the flow of the hot water circulating to those radiators furthest from the boiler and conversely minimise the flow to those closest to the boiler. The flow is controlled by opening or closing the lockshield valve on the radiator - this is the one that isn't the TRV and doesn't have a control knob. You normally have to remove the lockshield valve cover (sometime screwed on, sometimes not) and then use a small spanner or pliers to open and close the valve. I'm sure that there are guides on web. If you have a spare hour then give it a go. I know that you're looking for someone to do this for you but I hope that helps.

Thanks ed_pete. I've seen this online and was going to try it; plumbing is a bit old and clunky in our house and we've had a pipe burst before so a bit nervous about messing with the heating system! Maybe if we're feeling brave at the weekend...

      Assistance Dogs - Autism: any experiences?

      By JMK · Posted

      https://www.assistancedogs.org.uk/information-hub/assistance-dogs-emotional-support-dogs-and-therapy-dogs/   hello   i’d be interested to understand if anyone.has experience of Assistance Dogs especially for autistic children of different ages for emotional support and therapy   There was a prior thread on this topic on EDF 10 hrs ago but it had limited experiences and there was a (claimed) change in UK legislation in 2019. Whilst the industry appears unregulated/unlicensed, there are several providers (approx 15, perhaps more) who claim to have fully trained dogs or say that they can help families to train a puppy/young dog over the 18-24 months.  The latter obviously comes with a need for strong commitment to the challenge. Costs for a fully trained assistance dog are quoted at £13-15k albeit they claim £23k total cost to train the dog. On the one hand, this could potentially be a useful solution for some families if such a dog was truly trained as their websites claim and such a dog was accepted in public places and schools etc… On the other hand, I don’t think that I’ve ever seen an assistance dog of this type or in this context (only for a blind or partially sighted person) and hence a real risk of fraud or exploitation! The SEN challenge for families coupled with limited resources in schools or from local authorities or the NHS as well as the extremely challenging experience of many families with schools offering little or no support or making the situation worse leaves a big risk of lots of different types of fraud and or exploitation in this area.

      Hi there  We live on Woodwarde Road backing on to Alleyns Top Field.  Our cat Gigi has gone missing — it’s been about 24 hours now. She is a cream Bengal. Could you please check sheds, garages, or anywhere she might have got stuck please? And if you could keep an eye out or share on any local groups/forums, we’d really appreciate it. Photo attached.   Thanks so much! My name is Jeff on 07956 910068.
