About infrared heater running costs
Infrared heaters warm people and objects rather than the air, so they feel warm quickly in small spaces.
Typical sizes: 750 W, 1,000 W, 1,500 W.
How to spend less: Aim it at where you sit and switch it off when you leave the room.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
