Buying Guide
FAQs
What should I look for in a radiant space heater?
Look for heating capacity measured in BTUs or watts to match your room size. Check for safety features like tip-over protection and overheat shut-off. Consider portability, adjustable heat settings, and energy efficiency ratings.
How do radiant heaters compare to other types of space heaters?
Radiant heaters provide direct, instant heat to objects and people, unlike convection heaters that warm the air. They are more efficient for spot heating but less effective for large, open spaces. Infrared models are quieter and often more energy-efficient than ceramic or oil-filled heaters.
Are radiant heaters energy-efficient?
Yes, radiant heaters are highly efficient for targeted heating since they don’t waste energy warming the entire room. Look for models with programmable timers or thermostats to maximize savings. However, their efficiency depends on proper placement and usage.
What safety features should I prioritize?
Choose models with tip-over and overheat protection to prevent accidents. Cool-touch exteriors are essential if you have children or pets. Ensure the heater has a sturdy base and certification from safety organizations like UL or ETL.
How do I choose the right size radiant heater?
Match the heater’s wattage to your room size—typically 10 watts per square foot. For larger rooms, consider a higher-capacity model or multiple heaters. Check the manufacturer’s recommendations for optimal coverage.
What are the benefits of infrared radiant heaters?
Infrared heaters heat objects directly, providing immediate warmth without drying the air. They are often quieter and more energy-efficient than other types. Many models also include eco modes to reduce energy consumption.
Are radiant heaters suitable for large rooms?
Radiant heaters work best for small to medium-sized spaces or spot heating. For large rooms, consider a higher-wattage model or a combination of radiant and convection heating. Look for oscillating features to distribute heat more evenly.
How do radiant heaters compare in price to other heaters?
Radiant heaters are generally affordable, with basic models starting around $30-$50. High-end infrared models may cost more but offer better efficiency and features. Compare long-term energy savings with upfront costs to determine value.
