Swhs are widely used for residential and some industrial applications.
This way it is continously circulated in the so called primary circuit.
Later the water flows backs to the collector one more time.

Solar water heating swh is the conversion of sunlight into heat for water heating using a solar thermal collector a variety of configurations is available at varying cost to provide solutions in different climates and latitudes.
A collector or collectors that capture solar radiation a pump to activate working fluid circulation a storage system for the hot water an auxiliary or back up water heating system for use when sufficient hot water cannot be supplied by the.
Solar water heating systems almost always require a backup system for cloudy days and times of increased demand.
A backup system may also be part of the solar collector such as rooftop tanks with thermosyphon systems.

Conventional storage water heaters usually provide backup and may already be part of the solar system package.
Active solar water heating swh systems comprise five main elements.
