In winter, the solar water heater is basically not used, but half of the time the water is still warm, and if you add these water to the electric water heater after heating, use water than the water pipe energy saving. I don't know. Can it be achieved? The simpler the way, the better. Mainly solar water pressure problems.
I don't need to pump experience because the 6 floor to the 4 floor of the building we have enough pressure of water supply is not a large tank you have to pump even if the 6 floor to the 5 floor is also used to install electric water heater bath pump should be enough water pressure
When the electric water heater is injected with water, the water inlet angle valve of the electric water heater is switched on, and if the two angle valves are closed in summer, the utility model can be used normally
The water outlet of the solar energy can be connected with one of the three buses, one end of which is connected with the solar angle valve, and the other end is connected with the water inlet of the electric water heater (the water inlet of the electric water heater is also connected with a three pass and an angle valve)
