I live in Shaoxing, Zhejiang, and my home has been renovated recently. Is solar water heater or electric water heater practical? This house has two floors.
The price of solar water heater is higher, but the energy-saving effect is good, but you should buy a solar water heater with electric heating in case there is no hot water in rainy days. Electric water heaters are cheap, but they are inconvenient to use. It takes 30 minutes to wash one person before washing the next. Otherwise, the water is not hot enough.
