Water heating
Water heating systems in dwelling are typically:
- From central heating with hot water cylinder: the central heating provides hot water for space heating while also providing hot water via a separate storage cylinder.
- From central heating (no hot water cylinder): the central heating provides hot water for space heating and can provide hot water on demand negating the need for a storage cylinder, therefore requiring less space.
- Immersion heater: an electric element heats water in a storage cylinder, used solely for hot water (not for central heating).
- Instantaneous: hot water heated as needed by an appliance (not a boiler) fuelled by for example gas or electricity.
- Dedicated boiler: hot water supplied from a boiler only used for hot water (not central heating).
