Abstract

This invention regards an energy-saving control method for electric heater and its apparatus. It is an energy-saving method for water heater with temperature preserving function at two different, high or low, temperatures. By checking on the dropping speed of the water temperature in the storage tank, i.e. the water usage status, different water heating model will be adopted, the first energy-saving model or the second energy-saving model. In which, the switching condition from the first energy-saving model to the second energy-saving model is the temperature dropping speed of the water, observed for a long period of time, in the storage tank. A slow temperature dropping speed represents few or no user of the water; then the second model will be adopted for energy saving purpose. There is no need to perform energy saving function by setting up an on-off timing for the control of water heater's heating period. And it provides user the flexibility in the hot water using at any time.
