The Vokera Fuelsaver is a passive flue gas heat recovery device and can be fitted to a new or existing condensing Vokera Vision, Unica i or Compact A combi boiler.
The post heat exchanger device is located between the boiler and flue terminal. The device offers the potential to increase efficiency by capturing some of the heat in boiler flue gases that would normally be wasted. It uses this extracted heat to reduce the amount of fuel that has to be burned when providing hot water.
