Is the electric water heater always on to save electricity or is it turned on and saved as soon as it is used?

Turn off the power, the temperature of the remaining hot water in the bucket will decrease. If it is used more frequently, it will be heated again with electricity when it is turned on again. There is actually no big difference from the fact that it is always on. The most important thing is that you have to wait for a bath to be heated again. It takes time. However, if you do not use it for more than three months or for a long time, remember to turn off the power and drain the tank.

There are three specific situations for saving electricity

Electric water heaters can be roughly divided into several types, namely heat type and water storage type, but on the whole, the power saving criteria for several types of electric water heaters are basically the following three points:

1. Infrequent use (use hot water for a bath at least two days): It is best to turn on electricity and heat one hour before bathing, and turn it off after bathing. Normally leave the water heater in the off mode.

2. For home use every day, only for bathing, and hot water demand is not high: It is best to turn on the water heater about an hour before bathing to heat up.

3. For specific situations of frequent use (a water heater is used together in the restaurant kitchen and bathroom, hot water is used for cooking, washing dishes, and bathing): It is best to keep the water heater in the always-on mode, which can be based on the frequency of use and hot water To adjust the hot water temperature.

Power saving tips about water heaters

Choose a water heater with moderate capacity;

The water heater does not have to always pursue a large capacity. The larger the capacity, the more electricity it consumes. Usually a family of two can buy an electric water heater of 40-50 liters. When you use it, you can heat it according to your own water consumption. After the last person washes it, the water just runs out. This will save some electricity bills.

2. Adjust temperature according to seasons and regions

According to the difference of seasons and regions, especially for the above three specific conditions, the temperature can be appropriately lowered in summer and hot areas, and the temperature can be adjusted appropriately in winter and cold areas, which can also save electricity bills reasonably.

3. Deep cleaning must be done after using for 2~3 years

As the service life increases, the dirt on the inside of the electric water heater and the heating rod will become thicker, the heating rate becomes slower, and it becomes more and more power-consuming. Regular maintenance and cleaning of electric water heaters can also improve the use efficiency and increase the service life.
