Automatic switching between solar water heater and electric water heater [Copy link]

This post was last edited by Jing Yun on 2019-6-23 23:49

The home is equipped with a solar water heater and an electric water heater. The temperature control output function of the solar water heater is used. When the temperature is set to 55 degrees or above, the output relay will be activated.

When the temperature of the solar water heater is above 55 degrees, close the water inlet valve and power supply of the electric water heater, and open the solar water outlet valve.

Otherwise, open the water inlet valve and power supply of the electric water heater, and close the solar water outlet valve.
