Heated tested versus 30" Oscillation... Black Remote Office Space Heater Showdown We’ve tested our fair share of large space heaters, but the Dreo Space Heater in black has exceeded our expectations. At 30 inches, it’s roomy enough to warm entire offices without overpowering. The 120° oscillation covers vast areas, ensuring even heating, while the adjustable thermostat keeps things cozy without overdoing it. We loved the five heat and three fan levels, offering precise control over warmth. The remote is a game-changer, allowing us to adjust settings from across the room without straining. We were particularly impressed by the 25dB quiet operation, making it perfect for busy workspaces. With eight safety protections and a one-to-12-hour timer, we feel confident leaving the heater unattended. So far, it’s our top pick for тихое, efficient, and reliable office heating.
