In the majority of properties we manage, there should be a resident’s manual which will explain how to use various controls in the flat including heating. In the majority of new build flats, the heating is provided by a Heating Interface Unit (HIU) and this provides heating and hot water on demand. There could also be underfloor heating installed. In older flats, it is most likely your heating will be provided by either a gas boiler, or electric heating. If you are in any doubt about heating or billing, please ask your Host.
