4000

Created from the DNA of the UK’s best-selling Greenstar i

Coming soon, the Greenstar 4000 keeps everything you love and then raises the bar with the ease of installation, commissioning and servicing.

The 4000 range includes:

  • 25kW and 30kW combi
  • 12 – 24kW system

With hot water flow rates up to 12.3 l/min, the Greenstar 4000 will be available in natural gas and LPG. It will also carry the same guarantee lengths as its predecessor the Greenstar i.

Quoting a Greenstar i Junior or Si boiler replacement (2005-2015 model)? Our simple switch wall-frame makes our new 4000 the easiest option with minimal pipework changes.

We cannot wait to soon share with you all of the features and benefits that come with the 4000!

Our Greenstar i boilers will still be in stock at merchants throughout May.
