The further feature of feature of the present utility model is that the PTC instant electric water heater adopts one of designer's of the present utility model beam to be better than a kind of through type electric water-heating apparatus of the utility model of the number of applying on April 20th, 1999 of accepting 99209215.9; The electric heater of storage-type electric water heater adopts a kind of PTC electric heating liquid heater of the utility model that the brave separate case of one of designer's of the present utility model beam applies for a patent.

The big I that one of advantage that relatively the utlity model has with existing similar techniques is to use power arbitrarily design adapts to the user of various supply lines.

Two of the advantage that the utlity model has is that the length of heat time heating time can be with the size design of setting power.

Three of the advantage that the utlity model has is energy-conservation.Because the electricity of PTC heating-thermal conversion rate mode high and that adopt Fast Heating water to be incubated again makes it energy-conservation.

Noiselessness and other environmental pollution when four of the advantage that the utlity model has is to use.

Five of the advantage that the utlity model has is to design not have incrustation scale formation when the water storage water temperature is 60 ℃, can not consider anti-incrustation scale design, and the work simplification cost is reduced.

Water power was isolated fully when six of the advantage that the utlity model has was heating, was not afraid of dry combustion method, and is safe in utilization.
