Worcester Greenstar 24i System Boiler
Greenstar i System is our most popular wall-mounted system boiler with outputs up to 24kW.
Suitable for a wide range of homes, this boiler 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.
