BBA approved, the Fabdec Excelsior WDE Indirect External Expansion Cylinder water heaters do not require a header tank so can be sited anywhere on the property, subject to suitable plumbing and water pressure.

- 3 bar pressure at outlets (subject to adequate incoming pressure)
- All sizes WRAS approved
- Cylinder guaranteed for 25 years
- Designed and manufactured in the UK
