Fuelsaver Passive Heat Recovery Unit (Boiler Plus)

Vokera Fuelsaver Passive Heat recovery Device

The Vokèra Fuelsaver passive flue gas heat recovery system consists of a post heat exchanger device that is located between the boiler and the flue terminal and offers the potential to increase efficiency by capturing heat recovered from the flue exhaust gases that would normally be wasted. This captured heat is then used to pre-heat the incoming cold mains water supply before entering the boiler, thereby reducing gas consumption and improving domestic hot water efficiency. The addition of a Vokèra Fuelsaver can save over 33% of the gas normally required for DHW; save up to 700kg carbon emissions annually and reduces cold water wastage by over 5% annually due to the inlet water being pre-heated.
