The Worcester Bosch Greenstar Ri boiler is a compact, wall-mounted boiler that is perfect for small and medium-sized homes. They also make a version for larger homes. (Not pictured here) It is also perfect for replacing a boiler in an existing system.

Small enough to be installed in a standard kitchen cupboard, the boiler can be used with our range of high-efficiency unvented hot water cylinders or your current hot water cylinder.
