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

Product Information

Drayton has launched its new auto-balancing TRV technology, available for two of its most popular ranges – the iconic TRV4 and RT414. 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. 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.

Browse universal radiator valve cap kits to replace an old or damaged cap, and radiator maintenance to enhance the life of your double or single panel radiator system. It is strongly recommended that the differential pressure across the thermostatic valves should not exceed 0. This Round Corner Thermostatic Radiator Valve and Lockshield Chrome Valves offers control over your radiator so you can heat your room in comfort. 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.

Drayton's TRV4s set the standards for design, performance and quality, and are now A-Rating for energy efficiency. As a result and given that you are not supplying direct, its somewhat doubtful that Id use your services again. The TRV4 body has a nice table that shows the correct setting for different radiator outputs but the EB has some complicated flow capacity graph that I can make head nor tail of. I had a couple of radiators which stopped working, I figured out the TRVs had failed somehow so I just took them off and everything was fine.

To avoid damage to the valves and the heating system components, and the formation of scale deposit in the hot water heating system, the system should be flushed and a proprietary inhibitor needed. As such, does anyone have any suggestions for the cheapest TRV's which have the body to allow the Tado TRV head to fit to the thread without an adaptor being needed? 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.
