The CAHP-120 is a fully integrated heat pump system designed specifically for commercial use. This water heating solution utilizes industry-leading heat pump technology to provide a more efficient way to heat water with electricity. By pulling heat from the surrounding air and transferring it into the tank, the heat pump also produces cooler, dehumidified air as a welcome by-product. Most importantly, by moving heat rather than generating it the CAHP-120 operates at an industry-leading 4.3 coefficient of performance (COP). It also has 119 gallons of storage capacity to maximize performance and energy savings. These two qualities make the CAHP-120 a low greenhouse gas emission, sustainable water heating solution and an integral part of any all-electric site design. The CAHP-120 may qualify for local utility rebates or credits where available. This fully integrated commercial heat pump water heater is backed by 3-year tank and 1-year parts/compressor limited warranties. The CAHP-120 is perfect for light commercial applications such as quick-serve restaurants, schools, retail buildings, and any other commercial application that would typically use a traditional 120-gallon commercial electric water heater. For larger applications, multiple CAHP-120 water heaters can be combined and used together. A. O.
