A gas-fired batch booster water heater for supplying sanitizing water to a dish washing machine comprises a chamber member, a water inlet tube, a gas-fired burner, a water outlet tube, a valve member, and a member for circulating water through the chamber member. The chamber member has a first opening operably attached to the water inlet tube and a second opening operably attached to the water outlet tube. The chamber member comprises an integrated heat exchanger and water tank. The gas-fired burner heats the water in the chamber member as it is circulated. The gas-fired batch booster water heater may further include a temperature sensor associated with the water inlet tube for controlling activation of the member for circulating water through the chamber member.

Gas-fired batch booster water heater apparatus

A gas-fired booster water heater for providing water at the sanitizing temperature to a commercial dishwashing machine includes an outer housing which is sized to be installed below a counter and contains a burner comprising a burner box and combustion chamber separated by an infrared burner combustion surface facing into the combustion chamber. A heat exchanger includes finned tubes disposed in the combustion chamber for continuous circulation therethrough of water to be heated during heater operation. The heater housing includes an access opening through which the burner box together with the combustion surface may be disconnected from the combustion chamber and withdrawn as a unit for service or repair without removal of the heater from its installed position below the counter.
