SimpleSwitch
With Greenstar i, i Junior and Si
Flexible
Pre-piping jig and rear piping as standard
Easy installation
Built on the tried, tested and much-loved features of the Greenstar i, the Greenstar 4000 is instantly familiar and yet totally transformed in appearance, performance and installer plus points.
Available as combi (25-30kW) and system (12-24kW), a key feature of the Greenstar 4000 is the front cover which can be removed by simply loosening two screws, as well as the right-hand side panel which can also be removed for easy access.
SimpleSwitch
SimpleSwitch refers to sharing the same positions for the top and bottom wall-frame screws, the pipework positioning, PRV, siphon and flue. This saves a significant amount of time when replacing a Greenstar i, i Junior or Si boiler.
Pre-piping jig
The wall-frame enables pre-piping for all pipe connections. This includes the condensate and PRV before the boiler is hung, making installation easier and quicker. Space for rear piping comes as standard, without the need for an additional spacer frame.
Control key
The Greenstar 4000 is compatible with our industry-first ‘RF key’ slot-in receiver, which provides wireless RF communication between the boiler and our controls. This enables you to quickly and easily fit our wireless Bosch EasyControl, Comfort+ I RF and Comfort+ II RF.
Intelligent Filling System
The Greenstar 4000 combi variant is compatible with our Greenstar Intelligent Filling System. Its unique software ensures the boiler maintains optimum pressure and recognises a significant or sudden leak in the system. It’ll prevent the boiler from overfilling and will alert the homeowner if the heating system is losing too much pressure.
