Installation and servicing is usually cheaper than other system types due to less equipment and plumbing - required. 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.

Hot water can be stored within the cylinder, beneficial for larger households where a lot of hot water is used. You can tap on a room and edit the schedule or access the room settings, where you can view the battery level for the thermostat, rename it and turn Open Window Detection on or off. Editing a schedule was made super-easy as a result of the ‘copy’ feature, which lets you duplicate a schedule with just one tap, rather than having to input it all for each day and on each device. 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. GRAVITY-FED SYSTEMS (conventional systems with vented hot water cylinder and non-pumped central heating)

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. 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. 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) 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. Also try our online Product Selector to find the right kit in just a few short steps. 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.

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. 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. Insights tab provides stats about the number of hours the heating has been switched on and energy saving made through Eco mode Can provide good pressure in some residential areas where mains water pressure is low, particularly if the water circuit is also upgraded with pumps. 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.

With its intuitive user interface, the Wiser Home app makes it easy to adjust your room thermostat and radiator thermostats. Set up your app in seconds using simple step-by-step instructions.

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 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.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.
