Hello everyone,
My CH system consists of a Baxi Bermuda back boiler, an indirect hot water cylinder with gravity circulation, and 7 rads fed from a conventional 2-pipe system.
Although the boiler is newish, the rads have got to be 30+ years old and are showing their age All their valves were leaking badly and/or had seized spindles.
Anyway, spent a fun Saturday replacing all the valves. I used decent ones (Pegler), upgrading to TRVs everywhere - except the hall (where the room stat is), where I fitted a lockshield valve at both ends. Much to my amazement, nothing leaks and all the rads get nice and hot
I can recall someone saying that balancing isn't really necessary if TRVs are used. Is there any truth in this, or were they having a laugh?
If balancing is necessary, are those infra-red thermometers (under £50) any use, or would I be better buying a pair of clip-on dial ones instead?
Cheers,
Nick.
