Want to know how the eTRV works?
- You just unscrew the existing head of your Thermostatic Radiator Valve, leaving the sealed valve body and pipework untouched.
- Then screw the eTRV head onto the valve body, there are adaptors supplied to fit most common valve bodies.
- Insert the supplied batteries
- Customise the TRV programmes using the supplied remote control. Full instructions are included
You can find an extensive FAQ section for the eTRV here
Clever and Quiet
The now old style of TRV operates using just one temperature sensor which is intended to measure the room temperature. It can also be affected by other variables such as horizontal or vertical fitting and whether the valve is open (where hot water flow will be in the pipe underneath it) or closed (so the pipe beneath it is cool). Unlike a traditional TRV, the eTRV has a twin temperature sensor assembly. The first sensor calibrates to the air temperature within the room while the second sensor at the base of unit senses the temperature near the radiator flow pipe. The eTRV then calibrates to a temperature offset which results in a far more accurate control of room temperature than a conventional TRV.
The eTRV has been independently tested and has been verified to be one of the quietest products on the market - the motor is barely audible (some sound will inevitably attenuate through the radiator and pipework). The biggest problem with motorised TRVs is that they can be noisy and part of the cost of the eTRV is the need for the high quality motor and precision engineered gears that keep the noise level to an absolute minimum.
