Turboflue helical-fin heat exchangers utilize hundreds of steel fins, engineered in a precise spiral design, to provide superior heat conduction and fuel efficiency. This patented maintenance free technology is the cornerstone of the exceptional thermal efficiency levels found across Bock Water Heaters.
The latest in Bock’s line-up of high efficiency, state of the art water heaters, ElectriTHERM utilizes a digital control system with LED diagnostic readout for exacting temperature settings and status. With immersion thermostat for superior set point accuracy, ElectriTHERM exceeds all standards for DOE standby loss. Dual cold inlets allow for ease of installation, thickest steel in the industry, and incoloy elements provide superior corrosion resistance and is why we offer a five year tank warranty. Simple ordering allows you to easily choose your correct tank size (50, 80 and 119 gallon), kW, voltage and field conversion kits.
