I have some old danfoss radiator thermostats with an RA fitting which I would like to change for some with a timer.
The new thermostats have the RAVL screw connector and came with a plastic adapter to attach over the RA valve. The plastic adapter is useless but on amazon and ebay there are people selling metal adapters, some appear to be brass/copper and some are an unidentified shiny metal.
I bought one of each and they work fantastically in terms of fitting them. However, is there a problem with mixing the metal of the adapter with the rest of the CH pipework? I understand that this adapter is not actually in contact with the water in the system, but is the humidity in the room enough for this to be a concern? Is there a type which is best to use or am I worrying over nothing?
