Why solar water heater is not big enough
Solar water tank is no pressure, using the water pressure and flow on the tank to the indoor plumbing distance of the natural pressure of water supply, household floor more down the pressure is bigger, the minimum water pressure lived on the top floor, the flow is minimum.
Is your house the top floor? It is possible that the gap is not enough, small water. Or is there water pipeline aging, some is not smooth
If you can not put a little water, it may be because there is no water in the solar energy, solar water heater control instrument is broken, for a line.Solar water heater vacuum heat collection tube (glass) because of too thick scale, heat absorbing performance greatly reduced, the replacement of vacuum heat collecting tube or a professional cleaning department, all the vacuum collector tube cleaning descaling.
