Provided is a hot water barrel structure for a water dispenser, the hot water barrel structure including: a hot water barrel having a water reservoir therein; a partition plate provided in the hot water barrel and dividing the water reservoir into an upper water reservoir part and a lower water reservoir part; an inlet pipe supplying water that is to be heated to the lower water reservoir part of the hot water barrel; a heater provided at the hot water barrel and heating water introduced to the lower water reservoir part to produce hot water; and a hot water pipe provided at the upper water reservoir part of the hot water barrel.

A heater with a recovery device for swelling water is provided. A water inlet pipe and a water outlet pipe are longitudinally provided on the heater. The recovery device is transversely disposed on the heater and connected with the water inlet pipe, such that the recovery device is coupled on to reduce the entire size. The recovery device is adapted to recycle and store the swelling hot water in the heater so as to provide an energy-saving effect and to stop water from dripping.

A water heater includes a water tank having an inlet and an outlet, and a flue extending through the tank. A nozzle is positioned near a first end of the flue, arranged so as to emit a fuel stream into the flue, and a flame holder is located within the flue in a position to receive the fuel stream and to hold a flame entirely within the flue. A controller variably controls a flow of fuel to the nozzle according to a temperature of water in the tank.

An oil boiler includes an outer container having openings at opposite ends, a combustion chamber that covers an opening at an upper end of the outer container and in which a combustion reaction occurs, a lower cover that covers an opening at a lower end of the outer container, a plurality of flue tubes to heat heating water flowing in the outer container by guiding combustion gas, a burner including a fuel nozzle that sprays fuel, an air nozzle that injects air, and a spark plug that ignites a mixture of the fuel and the air, and a flame tube part that defines a tube space by surrounding a partial space in which the mixture is ignited, the flame tube part including a flame tube having an open lower end and a recirculation hole formed through the flame tube such that the combustion gas is introduced into the flame tube.

A heating module for a water heater includes a heater and a housing mounted to the heater. The heater includes a conductive pipe and a heating film attached to the outside of the conductive pipe. A room is defined between the housing and the heater for transferring heat to the water. The heating module is located in the tank of the water heater. When water enters into the tank, the conductive pipe transfers thermal energy to the water flowing through the conductive pipe by way of thermal convention. The water in the tank is heated by the housing by way of thermal conduction. The temperature of the water in the tank is quickly increased by the two ways.

The invention discloses a boiling water heater, which includes a barrel shape internal tank body, a water inlet pipe, a water outlet pipe and a exhaust pipe, the upper end of the tank body, fixedly and hermetically connect to the first upper cover, the first upper cover is fixedly and hermetically connected to the second upper cover. One cavity is formed between the first and second upper covers, water inlet pipe passes through the second upper cover. An exhaust hole is set on the inner wall of water inlet pipe to connect to the cavity, a separation plate extended to the middle which is above the exhaust hole on water inlet pipe's internal wall. The invention has the characteristics of convenient installation and disassembly, convenient cleaning, and can ensure the quality of water flows out, and the production cost is low, and very safe for use.

A magneto-energy apparatus includes an electromagnetic field source for generating a time-varying electromagnetic field. A graphite foam conductor is disposed within the electromagnetic field. The graphite foam when exposed to the time-varying electromagnetic field conducts an induced electric current, the electric current heating the graphite foam. An energy conversion device utilizes heat energy from the heated graphite foam to perform a heat energy consuming function. A device for heating a fluid and a method of converting energy are also disclosed.

An apparatus for heating water comprises a main burner, a pilot burner, a valve assembly with a main valve and a pilot valve having a shutter, a magnetic thermoelectric safety assembly with a thermocouple device holding the pilot valve open in the presence of a flame in the pilot burner, a button member mounted on a rod that is slidingly guided in the valve assembly and an electrical ignition member supplied via an electrical connection circuit, a switch device in the circuit being designed to be switched by means of the button member so as to close the electrical circuit when said button member is pressed in order to carry out actuation of the magnetic assembly so as to open the passage of gas through the pilot valve towards the pilot burner and to ignite the pilot flame by means of the sparks generated by the ignition member.
