I want to fit a new thermostatic value to some radiators in this new house I've bought. It is a conventional boiler system (which I'm not used to) though it is so antiquated I shall be replacing it with a combi next year most likely.
The radiator valve looks like 22mm then there is the thermostatic bit and it goes into a 15mm copper pipe vie what looks like a bit of a reducer. This valve is made by Danfos and I think it is quite old. I'm used to seeing everything as 15mm. Anyway if I went shopping for a new themostatic valve can I get one thats 22mm (or whatever it is) or so I need some attachments. Do I need to be concered about the valve if I swap my boiler to a combi next year?
many thanks,
Much
