Room Heater Running Cost Calculator
See what a room heater costs to run. Pick the type, set the wattage, hours a day and your tariff, and get the electricity cost per day, month and winter — plus how much a heat pump would save.
Check your bill; ₹6–9/unit is typical, higher on top slabs.
1500 W for 5 h/day over 90 days · 7.5 units/day.
A reversible-AC heat pump would deliver the same heat for about a third of the cost — saving roughly ₹3,600 a winter.
A planning estimate. Electric room heaters are resistance heaters (COP ~1), so consumption is simply wattage × hours. Real cost varies with thermostat cycling and actual runtime; the heat-pump comparison assumes a typical COP of ~3 for the same delivered heat. And remember the safety rules — never run a fuel-burning heater in a sealed room.
