I have also recently installed these though I needed adapters from a company in Luton to convert my radiator valves to fit these. Conrad do supply them but they are around £9 each whereas I paid about £3 each. Batteries last over a year and come supplied with Duracell's. You actually don't need the thermostat in each room unless you want to see the temperature. The valves have everything in them but don't display the actual room temperature. I also didnt bother with the window sensors, so each room cost me about £26-£30. You can also get a switch so that when you leave the property you can turn all radiators down to a holiday setting. One slight drawback is that these are designed for the european market so the displays are upside down if mounted at the bottom of the radiator as is traditional in the UK. Another advantage is that these open and close the valves several times a day so prevents them from sticking during non-use in summer. You can hear them opening and closing as the motor works but it isn't too noisy. Only other thing is I managed to find a Conrad discount code so got a few quid extra off and they do occasionally have them on offer.

They come very well packed, complete with batteries and instruction and some adapters.

And finally, no at present you cannot control the boiler from them, so that is a bit of a disappointment.

Sounds interesting but how often do your need to replace the batteries on the valves?

Great pitch / deal . However, I missed the Remington advert sentence....I love the product so much I bought the company lol

Heated!

Great stuff! Gas is soo bloody expensive, for me it's double my electricity bill!

Can this system be wired to the boiler to turn it off when none of the radiators need heating?

Indeed but I know what he means. If the main room where the boiler thermostat is located is warm enough (because you should not have TRV's in this room), then the boiler will turn off even though the other rooms may be cold. Ideally you want the system to know if any room has a demand for heat and keep the boiler running until it is satisfied, which of course would mean putting radiator valves in the main room, removing the thermostat and controlling the boiler via this system. Probably a bit risky imho in case you lost the router for some reason and come hone to a sauna.

Good idea...BUT... they look bloody awful! :neutral_face:

would you care to share where you got the £3 adapters from? Thanks
