Abstract
A gas conveying water heater to prevent electric shock could avoid dangerous of electric leakage caused by conventional electric water heater. First, the non-conductive gas is heated and drawn into to an outlet unit arranged in water. Then the hot gas is discharged via passing through the outlet unit to form a plurality of small hot bubbles to heat water of the water pool. According to the requirements, the outlet unit may comprise a heat conduction structure for transferring heat energy stored in the hot gas to water. The present invention includes a gas conveying unit, a heat and temperature control unit and an outlet unit with a plurality of thin holes. Gas is pumped through the gas conveying unit and heated by heat and temperature control unit to form hot gas. The hot gas is delivered to the outlet unit and discharged to water to heat the water.
