@adamk what I like about these valves is that once set, your rads for rooms are set and shouldn’t get “unbalanced”.

For those interested, in these valves, if you decide to go ahead, DM or email me, editor@renewableheatinghub.co.uk and I’ll send you a code for a 10% discount.

Watched the latest homeowners qa and they mentioned some easy to balance lock shield valves. It’s something I need to look at in the winter as not had the HP that long. Or if they are not an option is there a reasonably accurate, or one I can calibrate, temp meter I can use to balance them.

If you don't need your trvs (and you shouldnt)  you can repurpose them as lsvs by removing the heads and replacing with  decorators caps.  Trvs generally have better 'valve authority' than old lsvs, ie the response to turning them occurs over a wider range of positions.  Old lsvs (and many new ones) are basically shut off valves so difficult to set precisely.  There is a heat geek video on valve authority. 

This doesn't have the easy set, calibrated, advantage of the frvs but may be easier than using your lsvs and avoids replumbing.

In addition its worth noting that some trv bodies have an adjustable flow rate restriction built in, eg Drayton ones, which you need a tool to set.  Again thus doesn't have the calibrated self maintaining functionality of the frvs, but may be useful in some cases.

That said I managed to balance my rads on the lsvs even though the adjustment on some of them was only in the last half turn.

@jamespa I found the same about the last half turn being the only effective part of the mechanism. Some chap called Toodles wrote an article for RHH and he found the same too!😉 Regards, Toodles.

I know.

 

Sadly many dont read articles, I keep referring people to the ABC guide that cathoderay wrote!  I must add yours to my list of referrals.
