Greenstar i System (27kW and 30kW) overview

Our Greenstar i System is part of the latest generation of smaller and lighter boilers with outputs of 27kW and 30kW.

This boiler, which can be fitted in a standard kitchen cupboard comes with a steel wall-mounting jig that not only allows pipes to go behind the boiler but also the ability to pre-pipe all of the pipework before the boiler is placed on the wall.

The appliance can be used with our range of high efficiency Greenstore cylinders.
