Heating Technology, Performance and Durability
Apart from specifications, the actual heating technology, real-world performance and durability of the geyser depends on factors like:
Havells Instanio Prime uses the patented FeroglasTM technology which coats the internal tank surface with a specially formulated dry powder coating. This Feroglas layer ensures water does not come in direct contact with the steel surface.
The ultra-thick steel plates enhance strength while the coating improves corrosion resistance and longevity even after years of usage.
The Crompton Amica employs Nano Polymer Bonding technology to reinforce the inner tank to withstand high temperatures and pressure gradients. This provides excellent protection against corrosion and oxidation to increase the tank lifespan.
Havells has incorporated Whirlflow technology in the Instanio Prime which enables faster heating by separating the cold and hot water flows inside the tank optimally. This allows maximum heat transfer to the water for better energy efficiency.
The Instanio Prime also utilizes sturdy Incoloy glass coated heating elements which are highly resistant to oxidation and corrosion at high temperatures. This results in better heating performance.
The Crompton Amica uses an ISI-marked nickel coated copper heating element with thick walled copper for good thermal conductivity. The element traces are insulated with powder coating for smooth performance. It delivers excellent heating efficiency to heat up water rapidly.
Both geysers are designed with high-density PUF (Polyurethane Foam) insulation between the outer body and inner tank. This minimizes heat loss and ensures the water retains the desired temperature for long hours.
Crompton Amica’s 5-star energy rating indicates it likely has thicker insulation for better heat retention and reduced energy wastage. Proper insulation cuts electricity consumption and saves on your power bills.
