Description

Introducing the Greenstar 4000

Built on all the tried, tested and much-loved features of the Greenstar i, the Greenstar 4000 is instantly familiar and yet totally transformed.

We've raised the bar with the speed and ease of installation, commissioning and servicing, alongside improvements in efficiency and control. We've even made the price the same as its predecessor.

The 4000 range is available in both natural gas and LPG for:

  • Combi - 25kW and 30kW with hot water flow rates up to 12.3 l/min.
  • System - 12 - 24kW

The 4000 will also carry the same guarantee lengths as its predecessor the Greenstar i. Please note the Greenstar i System 27 and 30kW variants with the WB7 compact heat exchanger will continue to be available.

Our entire gas boiler range is able to run on a 20% hydrogen blend - so you can be confident it will run on gas for it's lifetime. Learn more
