Hi all.
I'm going to drain down my system today to secure a new rad to the wall which I put up, thanks to the help of the form, on my own last week.
I was also thinking that with the system drained I would set about changing a couple of TRV's that haven't worked for some time and which no longer work with the gentle persuation technique (hammer, tapping and pin pulling )
My question is for another TRV which comes off of a pipe that exits the storage cylinder about half way up the cylinder. There is a thin silver wire coming from the TRV to a small silver block attached to the storage cylinder about a quarter of the way up from it's bottom. Also, above the TRV is what looks like a valve that I can close or open.
I know what this thermostat is for but i'm wondering if it is a simple matter of twisting shut the valve above and swapping the TRV out. If so, then what's with this silver wire? I just checked it again and to confirm, it's attached to a silver block a quarter of the way up the cylinder. The wire spirals up from there and disappears into the body of the TRV.
