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 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.
To turn on the shower head normally, at least 0.5 MPa water pressure is required, that is, there is a height difference of 5 meters between the solar water heater and shower head. Otherwise, a booster pump must be installed.
The smallest booster pump (90 W) on the market can increase the pressure of water equivalid at a height of 10 meters. Wouldn't such a booster pump solve the problem?
