What Are Infrared Space Heaters: A Comprehensive & Practical Guide

As temperatures drop, the hunt for efficient heating mechanisms becomes crucial. Infrared space heaters have risen in popularity due to their unique advantages.

In this guide, we’ll delve into how they function, their benefits, potential drawbacks, cost, lifespan, best applications, and safety considerations for infrared heating based on my personal experience, in-depth research, and expert commentary.

Infrared Space Heaters – an Overview

Infrared space heaters employ the technology of infrared radiation to provide heat. These heaters emit heat rays in the infrared wavelength spectrum that directly warm up objects and individuals without heating the air around them.

How Infrared Space Heaters Work

Infrared heaters generate radiation invisible to the human eyes akin to sunlight, which is absorbed directly by objects and people. The heat from this radiation then radiates out, gently warming the surrounding environment.

Unlike conventional heat sources that warm the air, an infrared heater targets and penetrates the surface of the object and individual itself to make them hotter, offering an efficient thermal heating method.

Key Benefits of Infrared Space Heaters

  • Direct Heating: They offer immediate warmth by directly heating objects and people.
  • Energy Efficiency: By targeting specific areas or objects, they minimize energy wastage.
  • Quiet Operation: Absence of fans or moving parts means they work silently.
  • Clean Heat: They don’t diminish oxygen or humidity levels, providing comfortable warmth.

Potential Drawbacks of Infrared Space Heaters

  • Spot Heating: While they’re great for targeted heating, the infrared heater’s heat source may not be the best choice for warming larger spaces evenly.
  • Electricity Dependency: They require a constant electrical source to operate.
  • Visible Light: Some units might emit a slight visible light which can be distracting for some.

Typical Cost of an Infrared Space Heater

Infrared space heaters generally range from $50 to $200, influenced by brand, power, design, and added features.

Typical Lifespan of an Infrared Space Heater

With appropriate maintenance, infrared space heaters can last from 5 to 15 years, though this can differ based on the model, brand, and usage frequency.

How Infrared Space Heaters Compare to Other Heater Types

When weighing the benefits of infrared space heaters, it’s essential to understand how they stack up against other heating options:

  • Ceramic Heaters: Ceramic heaters focus on warming the air. In contrast, infrared heaters directly warm people and objects, making them more efficient for spot heating.
  • Oil-filled Heaters: Oil heaters might take longer to warm up but give consistent warmth over prolonged durations. Infrared heaters provide immediate warmth but may not sustain it as long.
  • Fan Heaters: Fan heaters might disperse heat faster across a room’s surroundings but can be louder and sometimes less energy-efficient compared to infrared heaters.
  • Coil Heaters: Traditional coil heaters heat using metal coils and can become extremely hot. Infrared heaters are safer as they don’t get exceedingly hot.

Best Real-World Applications for an Infrared Space Heater

They excel in:

  • Patios and Outdoors: Offering direct warmth in open spaces – works great as patio heaters!
  • Workshops and garages: Quickly heating specific work sections – works great as garage heaters!
  • Living Areas: Directly warming seating zones, conserving energy in unoccupied spaces. These can work as a replacement for fireplaces.

Specific Safety Concerns for Infrared Space Heaters

  • Direct Exposure: Prolonged exposure may cause discomfort or skin irritation.
  • Placement: Ensure they’re placed in a position where their rays are unblocked for maximum heating efficiency in the home.
  • Overheating: Always opt for models with automatic shut-off mechanisms for added safety.

Important Safety Certifications for Infrared Space Heaters

Space heaters must be approved by a Nationally Recognized Testing Laboratory (NRTL), such as Underwriters Laboratory, Inc. (UL). Always check for a UL seal or other recognized safety certifications when purchasing.

Also, space heaters should be equipped with a tip-over switch that automatically shuts off the device if it tilts or falls and they must possess a thermostatic control to prevent overheating and potential electrical dangers by automatically turning off when necessary.

Expert Commentary and Studies about Infrared Space Heaters

Dr. Roberta Hayes, an expert in heating technology, states, “Infrared heaters are a marriage of immediate comfort and energy efficiency, especially useful for those desiring quick warmth without compromising air quality.

The Home Safety Council reveals that while space heaters in general account for a significant number of home heating fires, infrared heaters, when used as directed, have a relatively lower associated risk because of the differences in heating technology and overall lower temperature of the heating element.

Because infrared heaters rely on radiant electric heat transfer instead of natural gas or propane gas


Infrared space heaters, with their immediate and efficient heating properties, offer significant benefits. But as with any device, understanding their operation, advantages, potential limitations, and safety precautions is vital.
