Drayton Wiser Smart Thermostat Heating Control Heating Only - Works with Amazon Alexa, Google Home and IFTTT

Product Information

HubR: User: Push Button/LED; I/O: Mains Relays (1-3), Digital Boiler Interface; Room thermostat: User: TFT display, touch buttons; I/O: None; Radiator thermostat: User: Twist Cap, LED; I/O: None 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. 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 doing this automatically turns on the hot water side as well, this would indicate a gravity system. ADVANTAGES OF GRAVITY-FED SYSTEMS (non-pumped) 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. Now that we’re clear what a combi boiler is, some combi boiler systems have two separate heating zones, controlled by two thermostats. CHARACTERISTICS OF COMBI BOILERS (two heating zones)

This is set up in the same way as regular conventional systems, but in this case the system has two heating zones being controlled by the boiler, with separate programming for each usually with two thermostats. This may be the case in larger or extended homes. CHARACTERISTICS OF CONVENTIONAL BOILERS (with unvented cylinder and two heating zones) 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). Hot water can be stored within the cylinder, beneficial for larger households where a lot of hot water is used. Away Mode overrides your existing schedules with a lower set temperature of your choosing, ensuring your home doesn’t get too cold while you’re away. You can turn off appliances in Away Mode, too. You can also set up geofencing using IFTTT so your system will automatically switch to Away Mode when you’re out of the house.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.

A combination or ‘combi’ boiler system combines a water heater and central heating boiler into one compact unit. These space-saving systems are increasingly popular amongst homeowners upgrading their older central heating systems and, according to the Energy Saving Trust, may be more efficient for smaller households with a low hot water demand – when hot water is heated and stored in a separate tank, heat can be lost when it’s not used. CHARACTERISTICS OF COMBI BOILERS (one heating zone)If, however, but turning on the central heating side, the hot water also turns on, this would indicate a gravity system. ADVANTAGES OF CONVENTIONAL BOILERS (with vented hot water and fully pumped) 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.

We also found it was easy to create some basic automations in the app using the Moments feature - such as turning the radiators in the lounge on, while also dimming the map connected to the Wiser smart plug to create a cozy atmosphere of an evening. App See if you have a time controller on your system or if it just on and off at the boiler. Controlling your system by turning the boiler on an off could indicate a gravity system. From the home screen, you can also view the weather for your location and sunrise and sunset times, too. The cog icon at the top of the home screen provides access to the main Settings menu, from where you can activate smart modes such as Eco and Comfort, and set a temperature for the Away mode. 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. Hot water is available on demand independently of the central heating, without having to wait for a water cylinder to heat up.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). HubR: Fixed wiring only, to comply with current IET regulations (BS7671); Room and radiator thermostat: No wiring required The Wiser Hub is the brain of your heating system and allows you to create up to 16 individual heating zones in your home. You can add one thermostat and up to 4 radiator thermostats to each zone. 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.
