If the liner is not cleaned for a long time, it may be scaling. This will not do any harm to the body, but it will affect the heating time, which is not very hygienic.
There are two kinds of electric water heaters, one is instant heating type and the other is water storage type; This happens when the water storage electric water heater is used for a long time. When this happens, for the water heater itself, there are the following changes:
(1) The conductivity of water changes. Generally speaking, the higher the conductivity, the shorter the service life of the tank, thus affecting the service life of the tank. ;
(2) The change of calcium and magnesium ion content in water will affect the scaling speed of water, and then affect the heating efficiency of water heater;
(3) The change of PH value of water will affect the anticorrosion performance of water heater.
