Overview

Water Geyser / Heater Electricity Cost & Power Consumption Overview

Understanding how much power your water geyser / heater consumes is essential for controlling monthly household utility bills. In India, power rates vary between ₹3.00 and ₹11.00 per kWh unit depending on your state tariff slab tier.

Operating a water geyser / heater with high energy efficiency ratings (5-Star or Inverter technology) significantly lowers your overall unit consumption, keeping your meter within lower pricing slabs.

⚡ Power Calculation Formula

How Much Power Does an Water Geyser / Heater Use?

Geyser Power (kWh) = (Geyser Element Wattage × Daily Hours × 30 Days) ÷ 1000

Example: 2000 Watts × 1 Hours × 30 Days ÷ 1000 = 60 kWh units per month.

How to Calculate Water Geyser / Heater Power Consumption & Cost?

Step 1: Identify Wattage (W)

Check the specification sticker on your water geyser / heater for rated wattage (e.g. 2000W).

Step 2: Multiply Hours & Days

Multiply wattage by operating hours per day and 30 days to get monthly Watt-hours, then divide by 1,000 for kWh units.

Step 3: Multiply by State Tariff Rate

Multiply net monthly kWh units by your state electricity tariff slab rate (e.g. ₹7.00/unit) to find total monthly cost.
