Dr Infrared Heater DR-238 Carbon Infrared Outdoor Heater

Check Price on Amazon

The Dr Infrared DR-238 uses carbon infrared heating elements and is rated IP55 for indoor/outdoor use. Infrared heaters warm people and objects directly rather than the air, which can be efficient in partially insulated garages or open door scenarios.

It offers three power settings (900W–1500W), a remote control, and plug-and-play 120V operation. Instant heat without combustion byproducts makes it suitable for occupied workspaces where air quality and odor-free warmth matter.

Consider infrared when you need targeted radiant heat for people working in place or when garage doors may be frequently opened. Infrared is often perceived as more efficient for spot heating because it reduces losses from heating large air volumes.

Buying Guide: How To Choose A Heater For A Small Garage

Selecting a garage heater requires matching the unit type to your usage, space size, and safety constraints. The following key purchase considerations help weigh options objectively.

1. Heater Type And How It Heats

There are three common types for small garages: forced-air electric (fan-forced or ceramic), infrared/radiant, and hardwired ceiling units. Forced-air heats the air and circulates it; infrared heats objects and people directly; ceiling hardwired models provide powerful distribution while freeing floor space.

2. Power, Coverage, And Placement

Electrical power (watts) and BTU ratings indicate potential output. For small garages, 120V 1500W portable units suit occasional use and spot heating. Larger, continuous-use needs or poorly insulated garages benefit from higher-wattage or hardwired 240V ceiling heaters. Consider where the heater will sit: near workbenches for task heat, or ceiling-mounted for general area coverage.

3. Installation Requirements

Portable plug-in heaters require no professional installation but need an appropriate outlet and avoid extension cords. Hardwired ceiling heaters typically require a qualified electrician for 240V wiring and secure mounting. Verify electrical circuit capacity and ensure the outlet or circuit can support continuous load.

4. Safety Features

Look for overheat protection, tip-over switches, cool-to-touch surfaces, automatic shutoff, and ETL/UL certification. For garages with flammable liquids, maintain distance from stored chemicals and follow clearance requirements. Infrared units often avoid heating air and can be safe for targeted warmth, but confirm any outdoor-rated model has an appropriate IP rating if the space is open.

5. Energy Use And Controls

Energy cost depends on wattage and duty cycle. Programmable timers, thermostats, and ECO modes can reduce runtime and energy consumption. For intermittent workbench use, a 1500W unit with a thermostat or timer often offers the best balance of control and cost.

6. Noise And Airflow

Fan-forced heaters produce airflow noise, which can be disruptive during fine tasks. Ceramic PTC elements often run quieter than coil-based units. Infrared heaters operate quietly because they don’t rely on large fans. If noise matters, review dB ratings or models with reduced fan speed or oscillation.

7. Durability And Construction

Garages can be dusty and subject to temperature swings. Metal housings and sealed elements increase longevity. For permanent installations, choose robust steel construction and corrosion-resistant mounting hardware. For portable units, consider models with protective grills and stable bases.

8. Ventilation And Indoor Air Quality

Electric heaters produce no combustion byproducts, making them appropriate for enclosed garages where carbon monoxide is a concern. Ensure adequate ventilation when running heaters for extended periods, and avoid using fuel-based combustion heaters in closed garages without proper exhaust.

9. Coverage Patterns: Spot vs Whole-Space Heating

Decide whether you need spot heating for a workbench or whole-space warming. Spot heating is best addressed by portable forced-air or infrared units placed near the workspace. Whole-space heating for a small, insulated garage may justify a ceiling-mounted or higher-output unit with louvers for distribution.

10. Controls And Smart Features

Remote control, timers, programmable thermostats, and smart integrations (Alexa/Google) add convenience. Smart scheduling reduces runtime and can lower energy costs, while basic manual controls reduce complexity and potential failure points.

11. Safety With Stored Materials

When a garage stores paints, solvents, or aerosols, follow clearance and storage guidelines from both the heater and chemical manufacturers. Avoid placing heaters directly under shelving with volatile substances and adhere to minimum clearance distances.

12. Maintenance And Filter Needs

Some forced-air units use simple washable filters or grills that collect dust. Regular cleaning improves airflow and prolongs element life. Infrared heaters typically require less maintenance but should still be wiped clean and inspected periodically.

Comparison Perspectives

• Cost vs Performance: 1500W portable heaters cost less and fit plug-in circuits but provide limited whole-space heating. Hardwired 240V ceiling heaters cost more to install but heat a larger volume more evenly.
• Safety vs Mobility: Portable heaters prioritize mobility and ease of use but need tip-over protection and careful placement. Hardwired units are fixed and reduce trip hazards but require professional installation.
• Efficiency vs Coverage: Infrared heaters are efficient for spot heating and when doors are opened frequently. Fan-forced units better circulate heat for enclosed, insulated garages.
• Noise vs Distribution: Fans improve distribution but generate noise. Infrared provides quiet, localized comfort with less air movement.

Use these considerations to match a heater’s strengths to how you use your small garage: occasional wrenching, daily workshop tasks, or general space heating. Choosing the right balance of output, installation, safety, and controls will deliver effective warmth without unnecessary expense or risk.
