The Worcester Greenstar 2000 Rear Spacer Frame is an accessory designed to facilitate rear piping installations for the Greenstar 2000 boiler range. This spacer frame provides a 70mm deep cavity behind the boiler, allowing for the routing of central heating flow, return, domestic hot water (DHW), domestic cold water (DCW), and gas pipes. By creating this space, the frame enables more flexible and efficient pipework configurations, which can be particularly beneficial in tight installation areas.​

The frame is compatible with the Greenstar 2000 series and is considered a time-saving accessory for installers, as it simplifies the process of rear piping. It's important to note that the Greenstar 2000 model comes with a fabricated stand-off kit, making it possible for heating engineers to configure piping to suit individual site conditions. Therefore, the rear spacer frame serves as an additional option for installations requiring specific pipe routing
