This paper introduces a storage water heater test system according to the GB 21519-2008 requirements based on PLC design. It researches the application of PLC in electrical energy efficiency testing. This system adopt PLC as the lower computer to control electromagnetic valve to water supplying and draining for the tested samples by reading the energy detector element signal to calculate the energy-consumption value; and through the change of the output quantity of weight sensor to calculate the volume of storage water heater, and using a temperature module prototype to measure the temperature values of each point. This system adopt PC as the upper computer, using the configuration software to monitor the on-site implementation, and through the friendly Interface to analyze, calculate and storage the energy efficiency values rapidly and accurately in real time. This system is designed to effectively improve the reliability and efficiency of energy efficiency test.
