Buderus-05052014-body.jpgBosch Thermotechnology has expanded its Buderus brand GB162 gas condensing boiler offering. The company claims by combining condensing and cascade technologies together in one compact design provides ultra-high performance efficiencies (up to 93% AFUE) with the ability to fit multiple boiler units into tight spaces.

The GB162 is ideal for wall or rack-mounted applications for multi-boiler cascades — up to eight units can now be cascaded. The GB162 is designed for applications like smaller commercial buildings and larger homes and has quiet in operation.  The units can be deployed in either TR back-to-back or TL in-line configurations with corresponding Cascade Kits for easy installations of up to eight boilers for total capacity up to 2664 MBH.  

The GB162 is equipped with a patented, extremely efficient aluminum silicate ALU-Plus condensing heat exchanger to ensure the longest possible operational life. Each unit can modulate down to 20% of total output for year-round efficiency.
