A.O. Smith Announces Higher Efficiency Residential Water Heater
The goal, A.O. Smith said, was to develop a heater that uses relatively low-cost available technologies to achieve higher efficiency with a modest cost premium. According to A.O. Smith, the Vertex's glass-lined helical coil heat exchanger made from low-carbon steel provides significant cost savings when compared to stainless steel heat exchangers. Furthermore, the helical coil heat exchanger design provides increased surface area, which combined with the length of the coil, enables Vertex to accept 76,000 Btu input while keeping heat energy inside the tank longer. The end result, the company said, was a revolutionary condensing water heater that offered 90% thermal efficiency, 76,000 Btu/hr input rate, significant recovery capability to provide endless hot water, and first-hour rating of 127 gph.
