Hello everyone,
I have a conventional boiler with quite old 1970/1980 radiators (see photo). Just a few beginner questions, hope you can help with.
1. The previous owners have somehow managed to lose all the valve cap. How do I figure out which one is the lockshield valve, which one is the original wheel head valve? I imagine I can close the radiator by either valve, but as the system might have been balanced via lockshield, I dont want to mess things up.
2. Is changing the valve to thermostatic a DIY-able job? Most of the guide I have read online is for combi boiler, and advise to get a gas engineer for a conventional system.
3. Without a thermostatic valve, is it possible to control the heat output of a particular radiator but closing down the wheelhead valve slightly?
4. I'm struggle to find replacement wheelhead cap for these. The spindle is the type with two flat sides and two rounded sides (see photo). Do you know where I can get them?
Many thanks for your help!
