A system boiler needs a hot water cylinder and are most commonly fitted together with a Megaflo type unvented cylinder, but system components are built into the boiler itself. Therefore no need for a feed and expansion tank as an expansion vessel is built into the boiler.
Homes which suit system boilers

- Ideal for properties with or planning on having a loft conversion as there is no need for any tanks in the loft.
- Best suited for homes with multiple bathrooms and high hot water demand.
- Frees up space as there is no need for a feed and expansion tank.
- System boilers are compatible with solar water technology for a lower carbon footprint and lower energy costs.
- Built in heating components (pump, expansion vessel etc) make installation neater and are covered under your boiler warranty
