Flue Gas Heat Recovery Unit overview

Our Greenstar Xtra is a compact, environmentally friendly and cost effective method of acheiving SAP target emission rates.

The unit is connected directly to the flue of the Greenstar boiler. Its highly efficient plate heat exchanger extracts residual energy from the flue gases exiting from the boiler. This energy is then used to pre-warm the water that is fed into the combi boiler reducing the amount of gas required to reach the desired hot water temperature.

The Greenstar Xtra incorporates a compact design to assist installation flexibility. The unit’s optimised height clearances offer greater siting options when installed with one of our gas combi boilers. Designed and built by Bosch, the FGHR unit is fully compatible with the latest range of Greenstar i, Si Compact and CDi Compact combi boilers.
