Drayton Wiser Smart Thermostat Dual Zone Heating and Hot Water Control - Works with Amazon Alexa, Google Home, IFTTT

Product Information

Heat Pumps are also supported and selectable in the app as the available heat source. Underfloor heating is also supported: wet systems need the Underfloor Heating Controller; electric systems can use the Drayton Wiser Eletrical Heat Switch. Comfort mode, meanwhile, learns how your home warms up, so the heating can be turned on early to reach your desired temperature by a set time.

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. Requires a two-channel Wiser kit ( Wiser Thermostat Kit 2 or Wiser Multi-zone Kit 2), to control the central heating via one channel and hot water via the other. Wiser thermostat and multi-zone kits 2 and 3 may be compatible with gravity-fed systems that have been retro-fitted or upgraded with pumps and cylinder thermostats - Please speak to our Technical Support Helpline on 0333 6000 622 for further advice on your system’s compatibility.Requires a three-channel Wiser kit containing two smart thermostats ( Wiser Thermostat Kit 3), to control the central heating via two of the channels and the hot water via the third. There’s also a two-channel kit, which adds hot water control into the mix for conventional boilers. If you have a home with a hot water cylinder, then you need this version. Also known as sealed or system boiler systems, a conventional boiler system with an unvented hot water cylinder uses a hot water cylinder that’s separate to the boiler but does not require a cold water tank usually typical of vented gravity-fed systems. CHARACTERISTICS OF CONVENTIONAL BOILERS (with unvented cylinder and one heating zone) Comfort Mode is there to make sure that your home hits the target temperature at the set point rather than turning the heating on at that point. In other words, if you get up at 7:30am and set a schedule to have your heating at 18°C at this time, your house will be warm when you wake up. Combi boilers only allow for one hot tap, bath or shower to be running at a time, by running more than one it will significantly reduce the pressure to each, which can be a problem for larger households with high demand for hot water.

The Drayton Wiser system lets you set a schedule for each thermostat, indicating a desired temperature for each room in your home at different times of the day. For example, you can set the bathroom to warm up first thing in the morning and last thing at night, if you don’t use it during the day. As already mentioned, you can override a set schedule at any time by manually twisting the top of the radiator thermostat (turning the heating on in that room for 30 minutes) or from the app, where you can choose for the heating to remain on for between 30 minutes and three hours. A system that was originally fully gravity-fed that has been upgraded/retrofitted with motorised valves, such that the central heating is now fully pumped - a recommended upgrade if full replacement of an older gravity-fed system is not possible. 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. A cold water feed or expansion tank is situated higher than the hot water cylinder, usually in the loft or attic.The Wiser 3 channel thermostat kit is ideal for properties with two heating zones. Control your heating and hot water more easily with smart technology. GRAVITY-FED SYSTEMS (conventional systems with vented hot water cylinder and non-pumped central heating)

That’s neat, as you can start with the cheap kit and then upgrade as you see fit to add TRVs to every radiator in the house. Once you’ve done that, the room thermostat can be used to control a room and all TRVs in it, as Wiser supports rooms with multiple radiators. Older systems upgraded with pumps provide better thermostatic control of the central heating and the ability to control it independently of the hot water. May be more economical to run for smaller households than other boiler system types according to the Energy Saving Trust.Hot water flow depends on the cold water mains pressure, so if this is supply is lost, you will soon lose the hot water supply. On the 2-channel programmer where you set your schedules, try setting the hot water side to off and the central heating side to on. If only the central heating side comes on and only your radiators get hot, you have independent control and thereby, a fully pumped system. Can provide good pressure in some residential areas where mains water pressure is low, particularly if the water circuit is also upgraded with pumps.
