Drayton Wiser Multi-Zone Smart Thermostat and 2 Smart Radiator Thermostat Kit - Conventional Boilers Only - Heating and Hot Water Control

Product Information

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). It 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. 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.

On the 2-channel programmer where you set your schedules, try turning off the hot water and turning on the central heating. If the central heating side comes on and only your radiators get hot, you have independent control and, thereby, a fully pumped system. Screw the Smart Radiator Thermostats onto the radiator valves where you have existing Thermostatic Radiator Valves (TRVs) Insights tab provides stats about the number of hours the heating has been switched on and energy saving made through Eco mode A combination or ‘combi’ boiler system combines a water heater and central heating boiler into one compact unit, removing the need for a separate hot water tank that can lose heat when not in use. Requires a three-channel Wiser kit containing two smart thermostats ( Wiser Thermostat Kit 3) to control the central heating via two channels and the hot water via the third.

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 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.

Only one tap, bath or shower can have hot water at one time in a system with a combi boiler vs a system boiler. This can be a problem for larger households with high demand for hot water. 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. HubR: Fixed wiring only, to comply with current IET regulations (BS7671); Room and radiator thermostat: No wiring required 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.Boiler Systems Explained: Conventional Boilers With A Vented Hot Water Cylinder And Fully-Pumped Central Heating Also known as sealed or system boiler systems, a system boiler uses a separate hot water cylinder. Unlike vented gravity-fed systems, this boiler system does not require a ​​cold-water​ tank. Characteristics Of System Boilers With An Unvented Cylinder (One Heating Zone) 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. Gravity-fed systems are no longer fitted new and do not comply to current building regulations, therefore homeowners are increasingly opting to replace older gravity-fed systems to either combi or fully-pumped conventional boiler systems.
