Rated 5 out of 5 by Save money - buy this Having suffered massive temperature swings as my old mechanical thermostat began to show the signs of age I decided to buy this. If you have a condensing boiler - this will save you money. The smart control algorithms help to ensure that the return water to the boiler is at a temperature where condensing can happen. I fitted this at the start of the heating season and I reckon I have achieved 15% savings, To do this you just need to set the required temperature and leave the thermostat to do its stuff. Trust me - it will. The only down side is that being a two wire device it clicks on and off all the time, even when the heating is off. In a quiet house in the dead of night this can take some getting used to if the thermostat is in hearing distance of you bedroom..... 16 May 2015
Rated 1 out of 5 by Form defeats function. This thermostat is nice to look at, but the designer has obviously forgotten that its purpose is to regulate room temperature. The temperature sensor is buried so deep inside the smart-looking casing that it has no chance of doing its job. As a result the thermostat overshoots the desired temperature by several degrees, and then has to wait for the room temperature to fall considerably before switching the heating on again. Circuit layout was designed by a complete dunce. Will only work properly if you drill a sizeable hole in the RH side of the casing to let air get at the sensor! Of course then your warranty is voided. I definitely do not recommend this product. 20 Feb 2015
