radiator valve
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 |

Your 15mm pipe will connect directly to the valve with no adaptor - although you will have to remove the existing adaptor, and may need to extend the pipe to suit. The part of the new valve which screws into the radiator will have a 1/2" BSP thread. If the old one is 3/4" BSP (which seems likely if it fits a 22mm pipe), you'll need a 3/4"BSP to 1/2"BSP reducer. I can see no reason why any new valves you fit should not be compatible with a combi if you fit one later. Roger |
