Frequently Asked Questions (FAQs)

1. What is a radiator Wheelhead?

The wheelhead valve is used for turning an individual radiator on and off. (“ Wheelhead valve” is sometimes shortened to WHV) Sometimes the inside of the valve cap has been chewed up so that it doesn't turn the valve spindle.

2. Do radiator valves fit all radiators?

You'll probably need a set of 15mm valves for your radiator, but if you're unsure then measure the diameter of your copper pipes to double check. The connection between your valve and the radiator is standard across all moderns radiators and valves.

3. Can I change a TRV without draining the system?

However, if you are only updating one radiator you can change the radiator valve without fully draining the system and there are actually benefits of doing so. For example, the water in your central heating system is filled with heating additives and inhibitor which protect the system.
