Regarding freezing of electric water heaters due to cold weather

Due to the influence of strong cold fronts, minimum temperatures are expected to drop below zero degrees across a wide area of Kyushu this weekend.
In the past, cold waves have caused the water supply pipes of eco-cutes and electric hot water heaters to freeze, resulting in some homes losing hot water.
