The manufacturer advises against using extension cords with this unit.

Buying Guide: How To Choose A Garage Heater

This buying guide outlines the main factors to weigh when selecting a heater for a garage. Garage environments vary—attached garages, detached workshops, uninsulated spaces, and areas where vehicles run—so choose a heater to match size, insulation, ventilation, and usage patterns.

Heat Type: Fan-Forced, Infrared, Or Radiant

Fan-forced electric heaters (ceiling- or wall-mounted) move heated air to warm the entire volume of a space; they are suitable for enclosed and better-insulated garages and for consistent ambient warmth.

Infrared heaters warm people and objects directly and can be more efficient in spaces with high ceilings or when spot heat is needed. Infrared is useful for covered outdoor tasks and semi-enclosed garages.

Radiant propane heaters provide powerful spot heating and rapid warmth; they are portable and effective for short-duration tasks. Propane requires strict attention to ventilation and carbon monoxide (CO) safety when used indoors.

Power Source And Electrical Requirements

Hard-wired 240V units deliver high wattage suitable for larger garages and workshops but require a dedicated circuit and professional installation. Confirm your garage’s electrical capacity and local code requirements.

120V plug-in units are simpler to install and portable, but they offer lower maximum output and are better for small or moderately insulated spaces. Propane heaters avoid electrical requirements but introduce fuel handling and ventilation trade-offs.

Coverage And Sizing

Match heater capacity to garage size and insulation level. Manufacturers often list square-foot guidance; treat these as estimates. For uninsulated or poorly insulated garages, select higher-capacity units or multiple heaters to achieve comfortable conditions.

Consider ceiling height: heated air rises, so infrared or radiant options can be more efficient for high ceilings since they target occupants directly.

Installation And Mounting

Ceiling-mounted units save floor space and distribute heat broadly but require sturdy mounting and access to a 240V supply. Wall-mounted or plug-in units require less installation effort and can be repositioned. For permanent solutions, ensure compliance with electrical and building codes.

Safety Features And Certifications

Look for overheat protection, tip-over shutoff on portable models, and ETL/UL listings for verified safety. For fuel-burning heaters, confirm oxygen depletion protection (ODP) where available and plan for CO monitoring and ventilation.

Controls, Timers, And Smart Features

Digital thermostats, timers, and remote controls support energy management and convenience. Wi‑Fi or smart-home compatibility enables scheduling and remote control; consider these features if you want to preheat a garage from a phone or integrate with home automation.

Energy Efficiency And Operating Cost

Electric heaters convert nearly all input power to heat, but kilowatt-hour costs determine operating expense. Infrared and radiant units can be more efficient for spot-heating. Propane BTU output and cylinder consumption affect fuel costs and should be estimated against runtime.

Durability And Environment

Garage conditions may include dust, oil, and intermittent exposure to humidity. Look for robust housings, enclosed motors, and sealed elements for dusty or workshop environments. Weather-resistant ratings (e.g., IP55) are important for units used in partially outdoor or unheated covered spaces.

Use Cases And Placement Tips

• Permanent workshop heating: Hard-wired ceiling heaters with thermostats and timers provide steady ambient warmth for ongoing use.
• Intermittent tasks or spot heat: Portable radiant or infrared units deliver quick comfort at workbenches or vehicle bays.
• Attached garages: Consider heaters with precise thermostats to avoid heat loss into the home; ensure electrical or fuel safety if an attached space shares air with living areas.
• Detached garages or outdoor-covered areas: Weather-resistant infrared heaters can extend comfortable working conditions outdoors.

Maintenance And Longevity

Regularly inspect vents, fans, and heating elements for dust build-up. Replace filters if present, and ensure electrical connections remain secure. For propane units, check hoses, regulators, and cylinder connections for leaks and follow manufacturer maintenance rules.

Regulatory And Safety Checklist

• Verify local building and electrical codes for hard-wired installations.
• Ensure adequate ventilation and CO detection for fuel-burning heaters.
• Position heaters to avoid combustibles and provide clearances per the user manual.
• Use certified electricians for 240V circuit work and follow manufacturer wiring diagrams.

Balancing heating type, coverage requirements, energy source, installation complexity, and safety features will guide the optimal heater choice for a specific garage scenario. Compare wattage/BTU, mounting style, and protective features against your garage layout and intended use to select an appropriate model.
