How a system boiler works
- Heats water and stores it in a sealed hot-water cylinder.
- Most major components are built into the boiler, so no loft tank is needed.
- Stored hot water can serve several taps and showers at the same time.
Who it may suit
- Homes with two or more bathrooms
- Households with high simultaneous hot-water use
- Properties with space for a cylinder
Less suitable for
- Small flats with no cylinder space
- Homes that only ever need one outlet at a time
