Solar Water Systems

Solar water heating systems or solar thermal systems use free heat from the sun to warm domestic hot water.

Solar water systems. The tank stores the solar heated water and serves as a backup heat source. 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. Each type of solar water heating system works best in different environments. Direct systems work best in areas that don t often see temperatures below freezing.

Swhs are widely used for residential and some industrial applications. Conventional storage water heaters usually provide backup and may already be part of the solar system package. How to select the right solar water heater. This is because the solar storage tank and the main water heater tank are part of the same pressurized domestic hot water system.

Active solar heaters are primarily of three types direct indirect and drain. Even if the water from the collector isn t shower hot you ll still save money since your tank will have had a head start heating the water. A backup system may also be part of the solar collector such as rooftop tanks with thermosyphon systems.

Hot water throughout the year. Indirect systems water is heated directly into solar collectors and circulating in your home it is best suited for cold or freezing conditions where the absence of heat exchangers means that cold cold water cannot be heated effectively. Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. A conventional boiler or immersion heater can be used to make the water hotter or to provide hot water when solar energy is unavailable.

Smaller passive solar water heater systems could cost around 3 000 while a larger active system could run you more than 10 000.
