A. O. Smith launches its commercial heat pump water heater for light commercial applications such as restaurants, schools, retail buildings, or any facility which would traditionally use standard commercial electric water heaters. The water heater has the highest efficiency and 50% more storage capacity than any other commercial integrated heat pump water heater on the market, A. O. Smith states. The integrated design and front-mounted components allow for an easy install and maintenance. It features a 4.2 COP and can save up to $3,500 in annual energy costs as compared to a standard electric commercial water heater, which results in an average payback on investment in two years or less, the company states. The CHP-120 is Energy Star qualified, making it eligible for many local utility rebates. A. O. Smith www.hotwater.com
