What each one costs to run
A 2,000 W storage geyser run 1 hour a day for 30 days uses 60 units (kWh): ₹310 a month at Gujarat’s top-slab rate of ₹5.20 a unit, ₹1,060 at Maharashtra’s ₹17.68.
Each row assumes the power its Amazon listing states, 1 hour a day for 30 days. On a lower setting, or while a thermostat has it switched off, it uses less.
Costs shown as a range across 13 states.

A unit is one kilowatt-hour: watts × hours ÷ 1,000. Cost uses each listed state’s top-slab domestic energy charge from its electricity tariff order, from ₹5.20 a unit in Gujarat to ₹17.68 in Maharashtra. Fixed charges, fuel and other per-unit surcharges, and duty are extra, and subsidies aren’t deducted. A home that uses fewer units, or has a smaller connected load, may pay a lower rate per unit; your bill shows your own rate. Rates and sources by state
