3 Ways to Cut Your Infrared Space Heater Energy Bill
- 🌱
Position the heater to directly face occupied areas — infrared heats objects, not air, so line-of-sight matters.
- 💡
Use the eco mode which alternates between 1500W and 750W to maintain temperature with less total energy.
- ⚡
Pair it with a ceiling fan on low reverse to push rising warm air back down without disrupting the infrared beam.
Infrared heaters use quartz or carbon resistance elements with no motor, so wattage is stable and consistent with no startup surge.
