Do 22mm bore trv’s exist. I want to control a 22mm heating run with a wifi trv head. Does such a thing exist (which I can then swap my WiFi Trv on to)
Failing that can you get zone valves that don’t need to be wired to the controller unit and so just run with a 240 feed?
Hive trvs just screw into a standard trv body, so if you can get one of those in 22mm flavour you should be ok
5lab - that was my thinking, the challenge is does a 22mm flavour exist.
Actually Looks like pegler do.
SF dont sell then but we do sell 22 to 15mm adapters. Either in end feed, compression or push fit.
You will cause a drop in flow though but it is an option
