Claim Text:
1. A portable water heater comprising: a supply container, positioned at a first elevation, said supply container at least partially enclosing a volume of water, an accumulating container positioned at a second elevation lower than said first elevation thus causing a pressure head differential between said first elevation and said second elevation, a heat exchanger having an inlet and an outlet, said heat exchanger located near a field-supplied heat source, from which energy is absorbed and transferred to a flow of water therein, a temperature-responsive valve having a first duct for fluidly coupling said supply container to said inlet of said heat exchanger, and a second duct for fluidly coupling said outlet of said heat exchanger to said inlet of said temperature-responsive valve, whereby said flow of water, caused by said pressure head differential, is automatically varied within a predetermined range by said temperature-responsive valve so that said volume of water is transferred from said supply container to said accumulating container at a temperature equal to that of said temperature setting.
