High-efficiency commercial water-heater development. Supplemental technical report, August 1984-August 1985

Technical Report ·
OSTI ID:6046803
The development of a condensing water heater for commercial applications was completed. The selected concept consists of a high-efficiency water heater connected by appropriate plumbing to a stratified-temperature storage tank. A number of pre-production prototypes were fabricated and installed at nine representative commercial sites. An initial year of field tests, starting in April 1983 and concluding in July 1984, consisted of a side-by-side comparison with the existing conventional water heater at each site. The test results obtained demonstrate standby loss rates less than one-fifth of conventional values and service efficiencies which average 32% higher than conventional-system efficiencies.
