The GB162 is capable of achieving efficiencies of up to 96%. This is due, in part, to its patented, extremely efficient, aluminum silicate ALU-Plus heat exchanger, but also because our advanced Energy Management System encourages the GB162 to remain in condensing mode.
Condensing technology has long been used in Europe. By condensing the water vapor in the flue gases into liquid water, the maximum amount of heat from the fuel is captured.
The condensing efficiencies of the GB162 can also be combined with the benefits of a cascading system to ensure you receive every possible bit of energy from the fuel you are burning.
