Electric hot water taps are more energy efficient than traditional water storage electric water heaters (or kitchen treasures).
Because power consumption = power × time. For example, if you burn a pot of water, the power of 2000W should be boiled for 5 minutes, and the power of 1000W should be burned for at least 11 minutes. Although the water absorbs the same heat, the surface of the kettle is still heated while heating. The longer the time, the more heat is dissipated. If the power is small enough, the water will never burn when the heating rate is equal to the heat dissipation speed.

According to the law of conservation of energy, the energy required to increase the tap water of the same capacity at the same temperature is constant. Whether it is a water storage type electric water heater (or kitchen treasure) or an electric hot water tap, it is essentially a heat exchanger that converts electric energy into When the heat energy of water and the thermal efficiency are the same, the heat exchange effect is the same. The difference is that the intermediate loss after the energy conversion to the end is different. The water storage type electric water heater (or kitchen treasure) is converted at the front end and exists for a long time. The preheating process of the time heat dissipation, heat dissipation and repeated heating, hot water pipe transmission heat dissipation, hot water waste left by the pipeline after water shutoff, etc., while the electric hot water tap is terminal heat exchange, no intermediate loss, power utilization up to 100% This is the biggest difference between the two different systems, and it is also the most outstanding performance of electric faucets in terms of power saving.
