TVRs – Let’s find out what you really know. Tick all that apply:
◻︎ I know what these are. TRV stands for thermostatic radiator valve and they’re the funny little knobs at the side of the radiator with numbers round them.
◻︎ They have something to do with controlling the water temperature in the radiators – don’t they?
◻︎ I guess the numbers round them are there to make them look like they’re a bit of proper engineering and don’t really mean anything much.
◻︎ The plumber very kindly set them all to ‘3’ when they were fitted throughout the house many years ago – I mean why would I want to change them to a different number?
