300L Solar Geysers FAQs

For most 2-4 person households, 150-200L is enough. 300L is best for larger families or homes with high hot water use.

Solar geysers use roof-mounted collectors to absorb sunlight and heat water. The heated water rises to a storage tank (thermosiphon effect) or is pumped there. On cloudy days, an electric element provides backup heating.

Quality solar geysers last 15-20 years with proper maintenance. The collector tubes may need replacement after 10-15 years. Regular maintenance includes checking the anode rod and flushing sediment annually.
