20% More Hot Water From the Same 15 Litres.
Whirlflow · Feroglas Tank · 5 Star · 8 Bar.
A geyser engineered for the two things that actually defeat water heaters in Delhi — hard water and high-rise pressure · Whirlflow technology delivering 20% more usable hot water by stopping cold and hot mixing inside the tank · a Feroglas anti-corrosion coated heavy-duty steel tank with a 7-year warranty · a Mcoloy glass-coated element that heats fast with minimal scaling · rated to 0.8 MPa (8 bar) for pressure pumps and multi-storey supply · a stainless-steel-core anode rod · 5-star energy rating with high-density CFC-free PUF · IPX4 splash-proof body
+20%more usable hot water
Here's what happens in an ordinary geyser: as you draw hot water out, cold water rushes in to replace it — and it mixes with the hot water still in the tank. So a 15-litre geyser never actually gives you 15 litres of hot water; the last few litres come out lukewarm, which is why showers run cold before the tank is empty. Whirlflow technology directs that incoming cold water so it doesn't mix directly with the heated water above it. The result is 20% more usable hot water from the same tank, and faster reheating. In practice it's the difference between one shower and two — without buying a bigger geyser or paying to heat more water.
Feroglas tank and Mcoloy element — built for hard water
Geysers rarely fail because the element burns out; that's a cheap repair. They fail because the tank corrodes from inside and starts leaking, and then the whole unit comes off the wall. Delhi's hard water accelerates that badly. Havells' answer is a heavy-duty rolled steel tank with a Feroglas anti-corrosion coating that resists both scale build-up and tough water — backed by a 7-year tank warranty, the number that actually predicts how long the machine lasts. Alongside it, the Mcoloy glass-coated heating element resists scaling, so heating stays fast and efficient for years instead of slowing as mineral crust builds up. A stainless-steel-core anode rod adds a third layer of corrosion protection.
A dual safety system, and an IPX4 body
A water heater puts mains electricity and water together in a humid room, so the protection matters more here than on almost any other appliance. The Greta Prime carries a high-precision thermostat and thermal cut-off against overheating, a dual safety adapter and a fire-retardant power cord guarding against shock and fire, and a multi-function safety valve plus a fusible plug managing pressure. The body is IPX4 rated splash-proof — meaning the internal electricals are protected against the water splashes and humidity that are simply unavoidable in a bathroom.
💧 Three defences against hard water
Feroglas Coating
Anti-corrosion layer between the water and the tank steel
Mcoloy Element
Glass-coated to resist the scaling that slows heating
Anode Rod
Stainless steel core, corroding so the tank doesn't
🛡️ Safety and efficiency
Thermal Cut-Off
Shuts down if temperature climbs too far
Fire-Retardant Cord
Plus a dual safety adapter against shock
Multi-Function Valve
Pressure relief and non-return, with a fusible plug
High-Density PUF
CFC-free insulation holding heat for longer
📦 In the box
Everything needed for a standard fitting is included — valve, pipes and fasteners — so there's no separate trip for parts, and we install it free across Delhi NCR.
The top rating, combined with high-density PUF insulation — the tank holds its heat between uses, so the element cuts in less often and the bill stays lower.
Built for multi-storey buildings and homes running a pressure pump, where a lower-rated tank would strain, leak at the joints or fail early.
Set the heat you want — lower through summer, higher in winter — which is the simplest way to cut the running cost of a geyser used daily.
Rust-proof and shock-proof plastic outer body that won't corrode in a humid bathroom the way a painted metal shell eventually does.
