Greenstar Ri (12kW to 24kW) overview

Our Greenstar Ri boiler is a compact, wall mounted boiler that is perfect for small and medium sized homes. 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 Greenstore cylinders for a complete Worcester system solution for your home.

† Up to a 10 year guarantee when installed by a Worcester Accredited Installer. Terms and conditions apply.

Our entire gas boiler range is able to run on a 20% hydrogen blend – so you can be confident it will run on gas for it’s lifetime.
