Vokera offers passive flue-gas heat recovery

Adding a Fuelsaver passive flue-gas heat-recovery unit to a Vokera combi boiler can increase the efficiency of producing DHW by over 33% compared with a standard condensing boiler. It also reduces water consumption by about 7%. A Fuelsaver unit is positioned neatly between the boiler and the flue.
Heat from flue gases is captured and stored and use to preheat incoming mains water before its enters the boiler.
Fuelsaver units are compatible with Vokera’s Vision C and Unica i condensing combi boilers.
