The basic design of a Batch Solar Water Heater consists simply of a water tank within an insulated box with a glass top.It is used to preheat water before it enters your conventional water heater. Thus it cuts down on the amount of conventional energy needed to heat the water up to the required temperature.But keep in mind, on sunny days a batch solar water heater can eliminate the need for conventional heating entirely.
