Lightwave Radiator Valve
The easiest way to take control of your heating and provide room by room control is to screw-fit a Lightwave Radiator valve (LW922) to your radiator. These devices link directly to the LightwaveRF App, and allow you to monitor, schedule and control each individual radiator independently. All the valves require are two AA batteries, and they will then automatically regulate your room temperature all through the winter. They can be used independently and do not require a separate room thermostat or any related controls for the boiler.
Install in seconds
Lightwave Radiator Valves, also referred to as TRVs, replace a pre-existing thermostatic valve (like the one in the picture). Simply unscrew the old valve and replace it with the Lightwave one. This can usually be done in seconds without special tools, and no plumbing is required. There is no danger of any leaks, as all you are doing is replacing the valve head, not the ‘seat’, which is the section that is connected to the pipework. The valve comes with adapter collars to accommodate the vast majority of radiator valve seats.
Control from the App
Once the valve is linked, from the Lightwave App you can view the real time temperature, turn the radiator temperature up and down, and create a room by room schedule for your home. Now you can have each room at the temperature you desire or conveniently turn off unused rooms to save energy; don’t heat the living room, for example, if you do not use it on weekday mornings. You can have up to 80 heating devices attributed to your Lightwave account.
Why does it save energy?
The Lightwave Radiator Valve really can help you to save energy. What some people don’t always realise, is that you can save energy even if your central heating boiler is still running. This is because turning off or reducing the set temperature of some of the radiators in your home means that the boiler isn’t having to provide heat to those unused rooms. Heat energy is therefore not lost through those radiators, and the boiler is not having to work as hard to reheat the water in the system. Turning off radiators in unoccupied rooms helped us to save up to 46% on energy costs during a trial at The University of Warwick.
