Drayton TRV4 Classic Thermostatic Radiator Valve TRV Body ONLY - no Head

Product Information

A thermostatic radiator valve is that little thing on the side of your radiator, and if you’ve ever wondered what a TRV is and how it works, then rest assured that it’s pretty simple. Drayton has launched its new auto-balancing TRV technology, available for two of its most popular ranges – the iconic TRV4 and RT414.

As the room cools, the Drayton thermostatic radiator valves open to allow more hot water through and maintain a constant temperature. Around 70% of UK homes do not have the minimum level of controls meaning that thousands of people are missing out on the cost savings they can bring.

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. The first main difference between thermostatic radiator valves and smart radiator valves is that you can select the exact temperature of your room, rather than a range. The valve itself is fine the thermostatic has a seized so it can't be turned, at least not without excessive effort.This behaviour has changed over the years - they definitely used to open more, making more noise as they did so and chewing through batteries faster.

They’re precise in regulating radiator temperature and can sense the temperatures you set and maintain them. A couple of the holes where the tommy-bar fits had burrs but these were easily removed using a round file. I want to replace the existing valve bodies with Drayton auto-balancing ones but am unsure whether I should use the TRV4 body (15 settings) or the EB body (6 settings). Complete your Smart Thermostat with Additional Smart Radiator Valves and take control of all your individual radiators.

If you really want to go down the smart route though a quick google turned up at least one system that says it replaces all the heads on the popular makes.
