Whether it is a flat panel solar water heater or an evacuated tube solar water heater, you can take a bath in winter.
Among them, the water tank of the flat solar water heater is located inside and is not afraid of freezing. The water tank has a built-in electric heater. When sunlight and heating are insufficient to produce sufficient hot water, electric heating can be used to achieve the heating goals and hot water can be used as usual.
Evacuated tube solar water heaters can also be installed with electric heating. The bottom of all water tanks is equipped with an electric heating installation port (if there is no sewage outlet, electric heating can be installed). Directly install the electrolytic heater, so that when the weather is bad, you can use the electric heater tor produce hot water.
