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

Product Information

This type of system is effectively an upgraded gravity-fed system, where the central heating has been upgraded to be fully pumped, while the hot water remains gravity-fed. This type of upgrade allows separate central heating and hot water timer control, unlike standard gravity-fed systems, due to the addition of motorised valves and a cylinder thermostat. CHARACTERISTICS OF CONVENTIONAL BOILERS (with vented hot water and fully pumped) A room thermostat controls the heating in your home. If the room's temperature drops below your chosen temperature, the thermostat will switch on. Once the room has reached the chosen temperature, the thermostat will turn the heating off, preventing overheating and reducing energy consumption. This can help reduce your home's energy consumption.

The Wiser 1-channel thermostat kit ideal for combi-boilers. Control your heating more easily with smart technology. 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. A cold water feed or expansion tank is situated higher than the hot water cylinder, usually in the loft or attic. 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)

These smart radiator thermostats replace the TRVs (thermostatic radiator valves) on your radiator, the type that let you adjust the temperature of the radiator manually. If you don’t have TRVs then you’ll need to bear the cost of changing your current valves to TRVs on top of the cost of the smart heating system. There’s no denying the radiator thermostats are bulkier than TRVs, but we found we didn’t notice them as much as we expected to. GRAVITY-FED SYSTEMS (conventional systems with vented hot water cylinder and non-pumped central heating) 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)

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) 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. 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.

Installing Wiser couldn't be simpler

We did notice a slight delay of around 10 seconds to one minute between boosting the heating from both the radiator thermostat or the app and the boiler springing into action. The further away from the Heat Hub the thermostat is, the longer the delay. Initially, we also struggled to get the radiator thermostat in the room furthest from the Heat Hub to remain connected to the system at all times. It would often drop the signal, meaning we were unable to control it via the app. However, after installing an optional Wiser Smart Plug – which also doubles as a range extender for the system – in a room between the Heat Hub and the troublesome radiator thermostat, connection issues were no longer a problem. Installation and servicing is usually cheaper than other system types due to less equipment and plumbing - required. 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. 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.

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. 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. 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. 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. 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.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 Less suitable for smaller homes due to the requirement for a water cylinder and cold water tank in addition to the central heating boiler. 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.

May be more economical to run for smaller households than other boiler system types according to the Energy Saving Trust.A combi boiler requires good water pressure, so may not be suitable in some residential areas where pressure is low. Hot water can be stored within the cylinder, beneficial for larger households where a lot of hot water is used. 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.
