High Pressure Solar Geysers

Last updated: January 28, 2026

Direct replacement for electric geysers. High pressure systems work with your existing mains water pressure.

Quick answer: choose high pressure if you want normal shower pressure and modern plumbing compatibility. High pressure (direct) solar geysers connect directly to your mains water supply, just like traditional electric geysers. They're the best choice when replacing an existing electric geyser without replumbing.

High Pressure Solar Geysers FAQs

High pressure if: replacing an electric geyser, want strong shower pressure, have mixer taps. Low pressure if: new installation with flexibility, budget is tight, don't mind gravity-fed pressure, can position tank above all outlets.

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.
