Abstract
The utility model relates to the field of electric appliances, and in particular relates to a water heater. The water heater comprises a shell, a heater and a double-layered sleeve. The heater and the double-layered sleeve are placed in the shell. The double-layered sleeve comprises a first sub pipe and a second sub pipe. The second sub pipe is sleeved outside the first sub pipe. The first sub pipe is internally provided with a first runner. An area between the pipe wall of the first sub pipe and the pipe wall of the second sub pipe is a second runner. One end of the first sub pipe is connected with a water inlet pipe, while the other end of the first sub pipe is connected with the heater. The water inlet pipe is communicated with the second runner. When the water heater is used, wastewater flows through the first runner and tap water flows through the second runner, and wastewater and top water exchange heat through the pipe wall of the first sub pipe to absorb residual heat in wastewater, so that the initial temperature of the wastewater is improved. Then, when wastewater is heated in the heater, the part of energy is not provided by the heater at the moment, so that the energy is saved and the cost is lowered.
