Thanks bro, could have said that earlier.

I would have but you just kept talking at me.

Brotherly love, lol 😂

We got two Nest zones and the Nest itself is silent, there is a tiny very quiet click from the little box it connects to when things turn on and off, but we only hear it if the cupboard they're in is open. If you get zones though you'll need two port valves.

Honeywell/Corgi ones are nice and quiet and well built, Honeywell slightly better. Our builder used non-Honeywell/Corgi for two in our cellar, one died and was replaced with a Honeywell and the other still works fine but is annoyingly noisy. Any two port valves installed in new house will be Honeywell.

£85 in Screwfix but I got our replacement one new from Ebay for £40.
