WATER HEATERS RECOVER WASTE HEAT McQuay scroll-compressor Templifier water heaters recover waste heat to make it available for space heating and domestic hot water. Units range from 500 to 3,000 MBH and can heat water up to 160 F (89 C). The hermetic scroll compressors feature low sound levels and use R-134a refrigerant, which has no ozone-depletion potential or phase-out schedule. (800) 432-1342 / www.mcquay.com
