Greenstar Wiring Centre

  • Allows wireless room thermostats to be used with a regular boiler.
  • Pump is wired direct and not to the boiler – saving as much as half a day’s installation time.

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.
