Consists of a central heating boiler and a separate, pressurised hot water tank fed directly by the cold water mains feed, so the tank heats and stores hot water at mains pressure. Alexa and Google Home support means that you can control your heating using your voice. Alexa recognises individual rooms so that you can adjust the heat automatically, and you can also find out what the temperature is in each room. As a general rule, larger households with multiple bathrooms and hot water heating demands should go for a conventional boiler system. Small, one-bathroom homes where space is a premium and hot water demand is low should look into combi boiler systems for instant access to hot water from an energy-efficient unit.

If you have a gravity-fed system, Wiser will only be compatible if it is fully pumped, by that we mean upgraded with motorised valves and a cylinder thermostat. Installation and servicing are usually cheaper than other common boiler systems due to less equipment and plumbing required. Requires a three-channel Wiser kit – you won’t require the third channel because the hot water control in a combi system is not separate. However, a two-channel kit is not suitable for a combi system with two heating zones, as the second channel is only suitable for hot water control in a conventional boiler system (with a separate hot water tank). Installation and servicing is usually cheaper than other system types due to less equipment and plumbing - required.A combi boiler requires good water pressure, so it may not be suitable in some residential areas where pressure is low. Insights tab provides stats about the number of hours the heating has been switched on and energy saving made through Eco mode The focus of Wiser is simplicity and our smart boiler control systems couldn’t be easier to install:

Timer and thermostat control of the central heating is available independently of the hot water due to a cylinder thermostat fitted to the hot water cylinder.A distinctive feature of a gravity-fed system is four 22mm or 28mm copper pipes connected to the boiler (sometimes three pipes if an injector T is fitted, but a fourth 22mm or 28mm copper pipe will still be nearby).

Drayton’s Wiser impressed us last year by being easy to set up and cheap to buy. This year, those two attributes still count, but the company has also made several underlying improvements, including IFTTT and Google Home support. The final component, the smart radiator thermostat, is a white plastic cylinder, which fit to the radiator once the existing valve has been unscrewed. To manually override any schedules you may have set, simply swivel the top of the radiator thermostat right to start the radiator heating, or left to stop heating. An LED on the radiator thermostat glows red temporarily when the radiator is heating, and blue if it's been turned off. Turning and holding the radiator thermostat will also reset or put it into set-up mode, depending upon how long you hold it in that position.It consists of a central heating boiler and a separate, pressurised hot water tank fed directly by the ​cold-water​ mains feed, so the tank heats and stores hot water at mains pressure.
