Solar water heaters utilize solar collectors to capture sunlight and convert it into heat. This heat is then transferred to water stored in a tank. Below is a comparison of key technical features of solar water heaters:

Feature	Description
Type of Collector	Flat plate or evacuated tube collectors are commonly used.
Storage Tank	Insulated tanks to minimize heat loss, available in various capacities.
Heating Element	Some systems include electric backup heaters for cloudy days.
Pressure Type	Available in pressurized and non-pressurized systems.
Material	Tanks are typically made from stainless steel or galvanized steel.
Efficiency	Varies based on collector type and installation angle.
Warranty	Most manufacturers offer warranties ranging from 5 to 10 years.

Types of Solar Water Heaters

Solar water heaters come in various configurations, each suited for different applications and climates. Here’s a comparison of the main types:

Type	Description
Active Systems	Use pumps to circulate water or heat transfer fluid.
Passive Systems	Rely on natural convection, requiring no pumps.
Split Systems	Separate collectors and storage tanks, allowing flexible installation.
Integrated Systems	Combine collectors and tanks into a single unit, ideal for small spaces.
Direct Systems	Heat water directly using solar energy, suitable for warm climates.
Indirect Systems	Use a heat transfer fluid to heat water, preventing freezing in cold areas.
