Pros

  • The 700W space heater low setting is perfect for maintaining warmth without cycling on and off constantly, which I found great for overnight use.

Air Choice Radiator Heater

#3 CHOICE Air Choice Radiator Heater, 700W Oil Filled Radiator Heater with Adjustable Thermostat, 2 Heat Settings & Overheat Protection, Silent Operation, for Bedroom, Office, Under Desk, White

Tired of noisy, drafty heaters that leave your small office or bedroom feeling either too hot or still chilly? The Air Choice Radiator Heater fixes it with steady, silent radiant warmth.

Why It Works
