GRAVITY-FED SYSTEMS (conventional systems with vented hot water cylinder and non-pumped central heating) A cold water feed or expansion tank is situated higher than the hot water cylinder, usually in the loft or attic.

Requires a three-channel Wiser kit – you won’t require the third channel because the hot water control in a combi system is not separate. However, a two-channel kit is not suitable for a combi system with two heating zones, as the second channel is only suitable for hot water control in a conventional boiler system (with a separate hot water tank). 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.A cold water feed or expansion tank is located higher than the hot water cylinder, usually in the loft or attic. 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. 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. 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.

Older systems upgraded with pumps provide better thermostatic control of the central heating and the ability to control it independently of the hot water. Central heating is not available independently of the hot water – water will always be heated when the heating is on. An initially gravity-fed system that has been retrofitted with motorised valves so that the central heating is now fully pumped. Screw the Smart Radiator Thermostats onto the radiator valves where you have existing Thermostatic Radiator Valves (TRVs)Honeywell Evohome gives more flexibility, with its custom actions and IFTTT channel. Its radiator thermostats are also more fully featured, letting you set the temperature you want from the room. If you want the most powerful and flexible multiroom heating system, then, we’d recommend Evohome. On the 2-channel programmer where you set your schedules, try setting the hot water side off and the central heating side on. If doing this automatically turns on the hot water side as well, this would indicate a gravity system. Disadvantages Of Non-Pumped Gravity-Fed Systems If, however, but turning on the central heating side, the hot water also turns on, this would indicate a gravity system.
