Will the water heater freeze when it is not used in winter?

Whether the water heater will freeze in winter depends on the ambient temperature.

If the temperature where the water heater is installed is below zero, it is necessary to electrify it to keep warm or drain the water in the water tank. If the water heater has a special drain nut, it is convenient to drain water. If not, it is necessary to electrify to ensure that the water temperature of the water tank is above zero. If the water in the water tank is below zero, it is easy to freeze the water tank and cause water leakage, which is difficult to repair.

Extended data

Water heaters usually do not need maintenance methods:

1. Drain all water from the water heater.

2. Turn off the water inlet switch, power supply or gas.

3. Remove the battery from the water heater.

Take a plastic film to cover the water heater and seal it, or take it down and put it in a dry and ventilated place.

The most important thing is that the water should be clear, and the water heater should not be turned on after drainage. Next time you want to use the water heater again, be sure to add water before starting it.
