100L Solar Geysers FAQs

Yes, for couples with efficient shower habits (5-7 minute showers). If you both shower in the morning, 100L provides enough hot water. For longer showers or bath users, consider 150L.
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.
