Is a system boiler right for your home?
System boilers work with a hot water storage cylinder, making them well-suited to larger households where several taps or showers may run at the same time. Unlike a heat-only (regular) boiler, all the major components are built into the unit — so installation is cleaner and faster.
We stock system boilers from the UK's leading manufacturers. Not sure which output or brand suits your property? Call us on 01494 580033 — we're happy to advise.
Best for
Homes with 2+ bathrooms, or where multiple hot water outlets are used simultaneously.
Key advantage
All components are self-contained — no separate pump, expansion vessel, or feed tank needed in the loft.
Requires
A separate hot water cylinder — typically installed in an airing cupboard.
