Title: Development of a long-life, stand-alone residential gas water heater. Final report, March 1985-August 1988

The objective of the project was to develop a residential gas water heater that offers improved features and utility, including higher overall efficiency, long-life and stand-alone control, i.e., an ignition and control system requiring no electrical connection for operation. A prototype water heater was developed and tested in the laboratory. Recovery efficiency, standby loss and the resulting service efficiency were close to targets. A 15 year tank life and low voltage, soft-wired control with intermittent ignition were also shown to be feasible. However, commercialization was not achieved for several reasons, including high projected price, unverified life and reliability of the TPTS heat exchanger production design and the withdrawal from the project by the manufacturing partner.
