  • Rapid response water heating and delivery system
    Patent number: 4556168
    Abstract: A rapid response water heating and delivery system having a flow restrictor which creates a pressure differential within the water inlet point to the heating system which is sensed by a pressure differential switch for activating the heating elements of the system. At a predetermined flow rate, the flow restrictor yields a threshold pressure differential which causes the pressure differential switch to activate the heating elements of the system. The pressure differential switch can be adjusted to actuate the heating elements at different desired levels of water flow through the system.
