Abstract: The CGRI high efficiency water heater was developed to provide energy conservation and durability features at an acceptable cost to the consumer. Recovery efficiencies of 82-85 percent compared to 70 percent for conventional heaters were obtained. The standby losses were reduced to 3-3.5 percent/hour of input from the values of 4.5-6 percent/hour for contemporary units. The merits of the CGRI high efficiency water heater lie in its simplicity of design, minimal additional first cost, solid field evidence of extended tank life, low operating cost, reduced service problems and ease of manufacture. The potential energy saving of the CGRI high efficiency water healer will make it economically viable especially in comparison to the operating cost of an electric water heater.
