The Greenstar Comfort range can be fitted with our Greenstar boilers when installed with our diverter valve kit.

Greenstar 8000 Life and Style system boiler (30 & 35kW) diverter valve kit - 7 738 112 913

Greenstar 4000 system boiler diverter valve kit (12 - 24kW) - 7 733 601 251

Simply plug ‘the key’ into the boiler and it is pre-paired with the Comfort control.  Once plugged in, you’re ready to go and set up your customers heating system easily. 

Our Greenstar Comfort+ does not come with a thermostat, rather it awakens the timer function on the 8000 Style boiler display itself.

The guarantee of our EasyControl, Comfort and Sense range will match the Worcester Bosch boiler that it is installed with (Terms and conditions apply). 

So when fitted with a Greenstar boiler and Greenstar System Filter, it will achieve the same extended guarantee length as the boiler.
