A circulation pump in the line that goes to the collector keeps water moving between them.
How to connect solar panels to hot water tank.
If the heat exchanger is external to the solar storage tank you may choose to use a natural convection loop between the heat exchanger and the solar storage tank or you may install a pump to force water through the heat exchanger and tank.
A second option to explore is the use of a dedicated solar thermal hot water heating system coupled with a heat pump to make the most cost effective option on the market.
Installing solar pv and using it to power an electric hot water system can be cheaper than installing a solar hot water system.
But because diverters are still fairly expensive it can be cheaper to put the hot water system on a timer so it turns on during the day when solar power is being produced and use the money saved to install extra panels.
One popular application for our submersible dc water heating elements is to prevent freezing in stock tanks used for livestock.

One solar panel would be enough to power a traditional storage hot water heater throughout a day as this is the most inefficient appliance used in most homes.
Simply wire the solar panel directly to the dc water heating element or through a thermostat to regulate the water temperature.
You can use a solar panel to make hot water or to keep water from freezing.
You split the cold water line feeding one branch into the storage tank and one into the collector.
