There is a square box under the solar shower head which contains the battery and voltage regulator. The solar shower is a shower that uses a constant temperature faucet and uses heat-sensitive temperature components to automatically adjust the flow ratio of cold and hot water so that the temperature of the mixed water outlet is always maintained within the defined range. The motorized pressure shower can mix the air, the water flow is faster, but does not sting the skin. At the same time, it can save 40% of the water flow equivalent to a regular shower head.
You can use a shower like this.
The effect of using a shower depends on the pressure of the hot water. If the water pressure of the water heater is high enough, the comfort of using this shower head will be very good. If the water pressure is not sufficient, the comfort of any type of shower head will notwill not be very good.
The hot water outlet pressure is relatively low. You can consider installing a hot water booster pump on the hot water outlet pipe of the solar water heater to increase the hot water outlet pressure value.
