Beschreibung
Zusammenfassung:	A tank-tankless water heater includes primary and secondary heat exchange rs, and a combustor for the production of flue gases. In operation, water is first heated as the water and flue gases flow through primary heat exchange r. The water flows into the tank where it is stored and again heated as the flue gases flow through the secondary heat exchanger. A pump moves the water from the secondary heat exchanger, through the primary heat exchanger, and back to the secondary heat exchanger for storage as needed to maintain the s tored water at a desired temperature Water is drawn from the secondary heat exchanger during initial demand to provide a ready source of hot water, and the hot water supply is maintained by the primary heat exchanger during sust ained hot water draws. The primary heat exchanger may include a temperature or temperature differential control system.
