Spherical surface laminated water heater

A spherical surface laminated water heater comprises a water tank inner container and heat medium tubes and is characterized in that the water tank inner container is filled with a spherical surface partition wall, so that an interlayer is formed at one end of the water tank inner container; a heat medium inlet pipe is mounted at the upper part of the interlayer; a heat medium outlet pipe is mounted at the lower part of the interlayer; an electric heating device is mounted at the other end of the water tank inner container; and a water inlet/outlet system is mounted at the bottom of the water tank inner container. According to the utility model, the problems that a heat medium tubular water heater has a complex structure and is low in heating speed can be solved; and the spherical surface laminated water heater is suitable for families and other various places to mount and use.
