HubR: Fixed wiring only, to comply with current IET regulations (BS7671); Room and radiator thermostat: No wiring required 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. 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. 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. 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)

Wiser allows you to build up your heating system as you go. Add smart plugs and radiator thermostats as required. By creating more independent heating zones, you can optimise your comfort and save energy.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. Drayton Wiser may be functional, but its plain all-white plastic design certainly isn’t stylish. If you prefer gadgets that make a design statement, this isn’t the smart thermostat for you. Wiser smart thermostats are compatible with most boiler makes and models, but it’s important to consider which boiler system type you have when selecting your Wiser kit. Here we’ll guide you through the most common boiler system types to help you find the ideal Wiser products to suit your home.

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) GRAVITY-FED SYSTEMS (conventional systems with vented hot water cylinder and non-pumped central heating)Powered by two AA batteries, the smart thermostat can be freestanding on a table or shelf, or mounted on a wall. It has three touch controls on the front. The plus and minus button allow you to adjust the desired temperature of the room, while the middle button boosts the heating in said room by two degrees. The screen automatically goes to sleep after 15 seconds to conserve the battery, but pressing any of the three touch controls will wake it up. 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.

Requires a three-channel Wiser kit ( Wiser Thermostat Kit 3) – note that you won’t require the third channel, because the hot water control in a combi system is not separate. A two-channel kit is not suitable for a combi system with two heating zones as the second channel in the two-channel kits is only suitable for hot water control in a conventional boiler system (with a separate hot water tank). Wi-Fi issues? Not a problem. The Wiser Hub allows local app access even when you aren’t connected to the internet. The firmware is updated via the cloud, ensuring your system is always up to date. 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). In residential areas with low water pressure a gravity or gravity/pumped system is usually the best option. Some systems incorporate a pump to help provide greater pressure at the taps.

Wiser Radiator Thermostat

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) Hot water is available on demand independently of the central heating, without having to wait for a water cylinder to heat up. 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. HubR: 148mm(w) 93mm(h), 31mm(d); Room thermostat: 76mm(w), 76mm(h), 25mm(d); Radiator thermostat: 93mm(h), 51mm(dia)

An older and more traditional system type, gravity-fed (or vented) installations feature a conventional boiler and utilise gravity and convection to heat water and distribute it to taps and radiators, rather than the water being pumped. Cold water from tank(s) in the loft flows down by gravity to a water cylinder where it is heated, it’s then forced to hot water taps and radiators at low pressure. Central heating is not available independently of the hot water – water will always be heated when the heating is on whether it’s used or not. The Heat Hub is a rectangular box with two buttons. One button activates the set-up process, while the other starts the whole system heating. LEDs above the buttons glow green when these options are active. The Heat Hub should be screwed to the wall next to your boiler. The square smart thermostat has a two-inch screen that shows the current temperature of the room it’s in, as well as the desired temperature. It also displays the relative humidity and battery level, and features a flame icon to indicate if the heating is switched on.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. Can provide good pressure in some residential areas where mains water pressure is low, particularly if the water circuit is also upgraded with pumps. 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.
