Logamax Plus GB162

Buderus Logamax Plus GB162

The GB162 is capable of achieving efficiencies of up to 93%. 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.
