3 Ways to Cut Your Portable Electric Radiator Energy Bill

  • 🌱

    Use the thermostat to let the radiator cycle — its thermal mass retains heat well between heating cycles.

  • 💡

    Place near the area you occupy most rather than trying to heat the entire room uniformly.

  • Use the low (600W) setting with the door closed rather than the high (1000W) setting in a larger area.

Startup Surge Information

Portable electric radiators use resistance elements with no motor, drawing stable, predictable wattage with no surge.
