Water in the solar tank is forced through connection piping and into the solar collectors by city water pressure. The sun’s heat is trapped in the collectors and transferred to the water inside. When the sun gets hot enough the circulation pump will bring the solar heated water down into the storage tank. The heater water rises to the top of the tank. The cooler water remaining near the bottom of the tank is pumped to the collectors completing the solar heating cycle. The circulation pump continues to run as long as the solar collectors can add heat to the water.
The photovoltaic (PV) module mounted next to your solar collectors on the roof generates enough electricity to run the circulation pump on a sunny day.
The storage tank has an electric heating element inside for extra heating when necessary. The element is controlled by a timer supplied with your system.
