About the Worcester Bosch Greenstar Si Compact range

A combi boiler from Worcester Bosch's Greenstar Si Compact range could be a great choice for homes with limited space. Designed to be an effective source of both heating and hot-water, their compact size does not compromise the quality of central heating; with flow rates of up to 10.7l/min and a central heating output of up to 24kW***.

The boilers come equipped with key features such as a user-friendly display and a variety of controls, designed to make heating your home as easy as possible.
