• condensing boiler Logamax plus GB 162 - 25T 40S

We present a new generation of economical heating technology from Buderus, which stands out through even more efficient use of energy! A whole range of important new improvements ensures that with the latest condensing technology you now heat with gas more economically than ever before – with maximum emphasis on your comfort. Output ranges of 15, 25, 35 and 45 kW are available. 

It is designed for single-family, two-family or multi-family houses and low-energy buildings. The boiler is ready for DHW preparation using the connected storage tank. The boiler has an integrated concentric flue outlet. The new electronic controller manages the modulating boiler pump and thus simplifies the hydraulics.

ETA plus

The modulating ceramic burner operates within an output range of 19 - 100%. This ensures longer burn times and reduces the number of switch-ons and switch-offs. Combined with the exceptionally efficient aluminium heat exchanger, the system ensures optimal condensing conditions all year round, and thus contributes to a boiler efficiency of up to 110.5%.
