Abstract
A condensing storage water heater system comprises an inverted burner at the upper end of a water tank or cylinder connected to a vertical flueway passing through the center of the vessel. A finned heat exchanger is arranged coaxially in the flueway and the primary circuit water flowing through the heat exchanger and the products of combustion pass through the heat exchanger system in countercurrent flow. The burner and/or primary circuit flow are controlled using at least one temperature measuring device located in the storage tank so that condensation will be achieved by the heat exchanger arranged in the flueway.
