ALU-Plus Heat Exchanger
The Buderus GB162 wall-hung condensing boilers use an advanced, aluminum ALU-Plus heat exchanger design. This lightweight heat exchanger has a number of innovative features to prolong its life and increase the efficiency of the boiler. Fins on the outside of the aluminum tube increase the exterior surface area. This means more hot flue gas comes into contact with the heat exchanger to maximize heat transfer.
A spiral channel on the inside of the tube increases the internal surface area and creates turbulence, bringing more water into contact with the heating surface, also ensuring optimal heat transfer. The surface of the heat exchanger tubes are treated with a patented plasmapolymerization process that leaves the surface so smooth that no deposits can adhere to it. In addition to also helping maintain extremely high efficiency, this keeps the heat exchanger clean.
Achieve Greater Efficiencies
Energy efficiency is not just applicable to residential boilers, even though that is what we most often hear of. Boilers for commercial applications—from offices and public buildings to hospitals, schools and colleges, multi-family dwellings, and sports centers—also have a significant impact on our environment. Companies and owners of commercial properties are increasingly looking to improve or upgrade their boiler rooms to maximize energy efficiency, but also to minimize their carbon emissions and increase the value of the building. Cascade systems, a relatively new development in heating technology, achieve significant energy savings because their output can be precisely controlled to match the demand for heating. Each individual unit comes into operation only when the demand is high enough for an additional boiler in the cascade to fire. A cascade system adapts particularly well to seasonal temperature changes by allowing heat output to be precisely matched to heating demand whether in summer or winter.
Thermal power = 13-62.6 kW (flow / return 80 / 60oC); Thermal power = 14.3-69.5 kW (return / return 50 / 30oC)
