Electric water heater: Poor, after all, uses electricity, and because it stores so much water, it does not dare to guarantee that there will be no leakage.

Gas water heater: medium gas is afraid of leakage, but the current strong exhaust can basically be eliminated

Solar energy: Gao basically eliminates the above two unsafe factors, but to consider the danger of lightning, you can do grounding or install lightning protection devices, and another way is to avoid taking showers in thunderstorms. There are no such hidden dangers.

Energy saving——

Electric water heater: It saves more electricity than gas, but the electricity cost is less, but I ca n’t save much. I am lazy. The electricity is connected all day long, so that it can be washed at any time, but the insulation needs electricity. Wash, how many people will wait patiently until 9 o'clock every day.
