The prices of electric water heaters in all major stores are flat, ranging from a few hundred yuan to thousands of yuan. According to the introduction of water heater experts, due to the different heating principles, the use of gas water heaters, the water temperature will be hot and cold. In comparison, electric water heaters are more able to keep the water temperature constant. Because its heating principle is to store water first, then heat, the water temperature is basically stable.
According to water heater experts, many people will worry that electric water heaters will also consume electricity when the power is not turned off, so the power of the electric water heater is usually cut off during the day. However, this approach may be counterproductive. For electric water heaters, insulation technology is essential. The most common misunderstanding in life is frequent power outages. Most of the current electric water heaters have a heat preservation function, but they must be completed under power supply. After the boiled water is stopped from heating, the temperature of the hot water can be maintained at all times while being energized. Once the main power supply is disconnected, the water in the water heater will slowly cool down, and when it is needed again, it will have to be reheated, which will in turn cost more. Therefore, for users who need to use the water heater every day, there is no need to cut off the water heater power supply. If the water heater is used once for 3 to 5 days or longer, it is more energy efficient to use the power supply after the power is turned off.
In addition, experts pointed out that "older" electric water heaters are prone to spontaneous combustion. In general, spontaneous combustion is attributed to short circuits. The electric water heater has been used for a long time, and various plug-ins including the socket are prone to failure, and the hidden danger of high-temperature ignition or short circuit is buried. Therefore, for older water heaters, users are better off.
