  • Space heaters are a convenient, energy-efficient solution for warming up large rooms during cold months, making them ideal for living rooms, open-plan offices, or other spacious areas. Available in various types—such as fan-forced, infrared, and oil-filled radiators—each offers unique benefits depending on your needs. Fan-forced heaters quickly heat a room by blowing hot air, infrared models provide immediate warmth to people and objects directly in front of them, and oil-filled radiators take longer to heat but retain warmth for longer periods. When selecting a space heater for a large room, consider heating capacity, energy efficiency, and safety features like tip-over protection and overheat shut-off. We tested eight space heaters to find the best options for different needs and budgets.

    Pros

    • Fast and even heating with wide oscillation
    • Quiet operation at just 40 dB
    • Multiple safety features for peace of mind

    Cons

    • May not be suitable for very large spaces

    • Remote control range could be better

    When we tested this Dreo tower heater, we were impressed by how quickly it warmed up our room. The 1500W PTC ceramic heating element kicked into action almost instantly. We found the 70° oscillation really helpful in spreading warmth to all corners of our space.

    One thing that stood out was how quiet this heater is. At just 40 dB, it’s about as loud as a library. We could easily watch TV or sleep without being disturbed. The touchscreen on top is easy to use, and we liked having a remote control for adjusting settings from across the room.

    Safety is a big plus with this Dreo heater. It’s made of flame-retardant materials and has tip-over protection, overheat protection, and a timer. We felt at ease leaving it on while we slept. The ECO mode is great for saving energy, as it adjusts power based on room temperature. While it works well for medium-sized rooms, very large spaces might need something more powerful.

    Safety-wise, this heater impressed us. It stayed cool to touch. The tip-over and overheat protection gave us peace of mind. Moving it was easy with the wheels. But it’s a bit big, so storage might be tricky in small homes.

Buying Guide

When shopping for a large room space heater, we recommend considering a few key factors:

Heat Output

Look for heaters rated for the square footage of your space. A good rule of thumb is 10 watts per square foot.

Energy Efficiency

We suggest checking the energy rating. Models with thermostats and timers can help save on electricity costs.

Safety Features

Auto shut-off and tip-over protection are must-haves. Cool-touch exteriors are great for homes with kids or pets.

Noise Level

Fan-forced heaters tend to be louder. If quiet operation is important, consider infrared or oil-filled radiators.

Portability

Weight and wheels matter if you plan to move the heater between rooms.

Heat Distribution

Look for oscillating fans or 360-degree heat output for even warmth throughout large spaces.
