eTRV: Remote control radiator temperature control

We love green at Latest Gadgets – grass, trees and low-power gadgets that make the world a better place. The eTRV – or electronic thermostatic radiator valve (sounds like a name out of Dr. Who) is the latter. Essentially, it’s a remote control radiator temperature control.

Made by heating control specialists Chalmor Limited, the eTVR easily replaces existing thermostatic radiator valves – simply unscrew the old and screw in the new.

If you’re unlucky enough to be stuck with even older radiator controls, you’ll need a professional to fit one of these (or a gutsy amateur). It’s not a major job, though.

The package comes with two parts – the eTVR itself and a universal remote control, which can adjust any eTVR unit it comes in contact with. Think of it as a Sonic Screwdriver for heating.

The remote uses Infra-Red to operate the eTVR, which means it won’t work in different rooms – and your dream of lying in bed and adjusting the downstairs heating is still a way away.

As well as being controlled from a remote, each eTVR has its own controls on the device, letting you turn up and down the heat to your heart’s content.

Each device also comes with a built-in thermometer, which shows the current temperature of the room as well as the temperature it is set to reach. There’s also a boost option to increase the heat for a 60 minute period.

Each eTVR also comes with three set time periods, allowing you to choose what temperature you’d like in each time period. For example, heat up the living room at night, but cool-down the unused home office. Then choose to turn down the heat in the bedroom during the day, but crank up home office warming.

Each unit is powered by batteries that expected to live for five years without replacement (they’re rechargeable), and Chalmor believe that you’ll save 25% off your heating bill if you switch to one of these and use it sensibly.

Oh, and for long-sighted purchasers, the buttons are huge. Like, really huge.

Retail price of the eTRV is £49.99+VAT and the handset costs £9.99+VAT.
