System boilers
A system boiler heats a hot water cylinder, so stored hot water is ready for several taps at once. Most of the kit is built into the boiler itself.
Get free quotesThe short version
- Needs a hot water cylinder, usually in an airing cupboard.
- Handles multiple bathrooms better than a typical combi.
- No loft feed tanks, it runs sealed and pressurised.
- Once the cylinder runs out, you wait for it to reheat.
Who it suits
Larger homes with more than one bathroom, or households where several people shower around the same time. Cylinder size and boiler output are set at survey.
