ABSTRACT:
Disclosed is a gas instantaneous water heater for use in boats or recreational vehicles comprising a housing divided into a large upper portion and a small lower portion. A gas valve and electric filament lighter are controlled by an electronic module which opens the gas valve and ignites the gas in response to a signal from a sensor capable of sensing water flow or a pressure drop. The heater employs a photoelectric flame sensor and a thermal override switch to shut off the gas in the event the igniter fails to ignite the gas or if the water temperature is excessively high.
