ABSTRACT:
A portable instant water heater. Water is delivered to a base unit of the instant hot water heater by a pump that draws water from a reservoir through a flow control valve. The water flows into a pre-heater that wraps around a base of the burner and that is heated by the burner. Water is heated in a heat exchanger and then exits the base unit through an outlet spout that swings out from the base unit to dispense water and that may be stored and locked into position in a handle for the base unit. The flow control valve may lower the flow of water through the heat exchanger, so the water has more time to absorb heat and to get hotter. The base unit includes a single control knob that turns on the pump and the burner and operates the flow control valve.
