Yes, there are two ways. The first is to add an electric heating pipe to the solar water heater. The advantage is that it saves costs on initial installation. The downside is that it's not safe. the entire water tank will waste electricity. There is also a multi-energy water heater. Solar energy and electric water heaters are separate. When water temperatures are high, solar energy is used. When the water temperature is not sufficient, the electric water heater is also used. time, solar energy can fill the electric water heater. It is still very practical to use.
Methods for sharing existing solar water heaters and electric water heaters at home:
Install a ball valve at the solar hot water outlet pipe ( inside). When you use solar energy, the. The valve opens and closes the valves(inlet and outlet) of the electric water heater at the same time, so that the solar water can be used. When using an electric water heater, simply turn off the solar valve and open the electric water heater valve.
Solar water heater is a device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production.
Electric water heaters are one of the three main water heaters, alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to heating power: water storage type (also called volumetric or thermal storage type), instant heating type and instant heating type (also called semi-water storage).
