In this guide, we show you how to upgrade your old radiator valves with TRV’s.

By doing this you’ll be improving the efficiency of your heating system.

Watch the video guide or follow the simple steps below for full instructions on how to install TRV’s to a radiator.

Before buying TRV’s you’ll need to decide what style you want – angled or straight – use our Radiator Valve Guide to help you make the right choice.
