Why the flux in the outlet is small?
The common solar water heater is non-pressurized that two reasons can cause the small flux. One is the solar water heater is not assembled at a high position. The vertical gap between the heater and nozzle is not large enough (especial on the top ground).The way to solve this problem is to increase the height of the heater or enlarge the diameter of the pipes. Another problem is the pipes are bending. The way to solve this problem is to re-settle the pipes. The third problem is that the something blocks the outlet, inlet or the pipes. The method to solve this problem is to call us to examine it.
