  • Patent number: 5460161
    Abstract: An apparatus and method for heating and delivering water by use of a campfire, comprising drawing water from a first kettle through a supply hose to a heat exchanger that is placed in the campfire. The water in the heat exchanger boils to cause a discharge of water upwardly through a delivery tube to a collecting kettle, after which the pressure in the heat exchanger drops to cause a further supply of water to be drawn from the supply kettle to the heat exchanger. Thus, quantities of hot water (e.g. a cupful in each quantity) can be discharged at short intervals (45 seconds or so) to supply cups of hot water for a beverage such as coffee, tea, etc. Other embodiments are arranged to draw water from a lower location up to the heat exchanger and then pump the water upwardly to a storage container.
