What is the primary energy efficiency of an electric water heater?
Instant heating electric water heater:The utility model has the advantages that the hot water is fast, only 3 seconds can be needed; the quantity of hot water is not limited; the heating water can be continuously supplied; the volume is small; the appearance is exquisite; the installation and the use are convenient; the number of hot water needs, and the amount of electricity consumed; the energy consumption is less.Disadvantages: high power required to reserve at least 4 square wires.
Electric water heater is divided into two types: water storage type and instant heating type (also called fast type).Water storage type electric water heaterThe water storage capacity is 30L, 40L, 50L, 60L, 80L, 90L, 100L and so on.Advantage：Installation is simple, easy to use, free from the influence of gas floor pressure difference, more and more users preferred.
A water heater is a device that uses a variety of physical principles to raise the temperature of a cold water into hot water for a specified period of time. According to the principle, it can be divided into electric water heater, gas water heater, solar water heater, magnetic energy water heater, air energy water heater, central heating water heater and so on.
The level of energy efficiency, energy consumption coefficient of not more than 0.6 hours of 24 natural hot water output rate greater than 70%. Energy efficiency grade 2, 24 hours of natural energy consumption coefficient is less than 0.7; the hot water output rate greater than 60%.
