I've had some good help from this site so far regarding my radiator problems and I'm now ready to fit some TRVs when I drain the system today. However I'm worried about buying the wrong type of TRV for my system as my radiators seem to have very old and thin pipework. Could you take a look at this photo and let me know what connection I need for the job? (sorry about the rotation but it's how my phone insists on uploading it and I can't seem to edit it on the site)
They all look like this on both sides (trying to work out which side gets hot first but there's not much in it). Some still have the plastic valve handle (again identical on both sides - they are Myson branded) but underneath they all look like this. I'm just a bit nervous of the size of the pipework as it seems extremely small compared to the valve fitting?
Any general fitting advice would be welcome too...
