What is a Solar Geyser
Solar water heating is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications.
Turning sunlight into heat is no problem. The core of a solar water heater is a solar collector (flat plate or evacuated tubes) and a storage tank (geyser).

Evacuated tube solar collectors offer outstanding performance and efficiency and consist of a heat exchanger and a series of heat collector tubes.
Advantages of evacuated tube systems include
- Evacuated tubes contain practically no water and so they can resist freezing conditions.
- The curved shape of the tubes allows thermal absorption from a greater range of sun angles, and therefore for a greater portion of the day.
- Tubes permit high heat retention and so much of the heat collected during the day can be retained during overcast days and through the night.
- Tubes fit independently in the header pipe and can be individually removed and replaced without having to decommission the entire system.
- Tubes provide lower aerodynamic drag due to air being able to run around them, proving less wind-drag in some high wind locations.
- Work exceptionally well on cloudy/overcast days.
- The large bore header-pipe ensures reliability in hard water (high calcium hardness).
