Abstract
The invention relates to an electric shock preventing gaseous conductance water heater and avoids the electricity leakage risk possibly caused by traditional devices which electrically heat water body. Firstly, non-conductive gases are heated to form hot gases, then the hot gases are introduced into a gas discharge unit which is placed in the water body, then the hot gases are discharged from the gas discharge unit in a mode of a plurality of small hot gas bubbles so as to heat the water body in a pool, and the gas discharge unit can comprise a heat conduction structure according to requirements so as to help transmit the heat energy stored in the hot gases to the water body. The electric shock preventing gaseous conductance water heater comprises a gas transmission unit, a heating temperature control unit and the gas discharge unit with a plurality of small holes, the gases are extracted by the gas transmission unit and heated by the heating temperature control unit to form the hot gases, the hot gases are transmitted to the gas discharge unit to be discharged to the water body, and thereby the water body can be heated.
