Power And Coverage
Wattage determines heating capacity. Smaller garages (up to ~400 sq. ft.) often suit 3000–5600W units. Larger or poorly insulated spaces typically require 7500–10000W. Use a conservative estimate of required power when ceilings are high or insulation is limited.
Installation Type: Hardwired Vs. Plug-In
Hardwired units are common for ceiling/wall mounting and require electrician installation but provide a clean, permanent setup. Plug-in models with a NEMA 6-30P plug are easier to install if you already have a compatible 240V outlet.
Mounting And Airflow
Ceiling-mounted heaters free floor space and distribute heat broadly. Wall-mounted units can direct heat to a specific work area. Adjustable louvers and variable mounting angles help direct airflow where it’s needed most.
Controls And Convenience
Look for digital thermostats, remote controls, and timers to set desired temperatures and runtime. ECO modes and precise temperature control help reduce energy use and maintain comfort consistency.
Safety Features And Certification
Prioritize units with overheat protection and ETL or equivalent safety certification. Durable housings (e.g., SPCC steel) improve longevity and protect heating elements from workshop wear.
Electrical Requirements
Confirm your garage’s electrical capacity and breaker rating before purchase. Large heaters (7500–10000W) may require dedicated circuits and higher-amperage service. Plug-in heaters typically require a NEMA 6-30R outlet and 30A circuit.
Noise And Fan Operation
Fan-forced models provide faster heat distribution but can generate noise. If noise is a concern, check manufacturer noise claims and consider installation placement away from frequent workstations.
Durability And Warranty
Heavy-gauge steel construction and warranty coverage indicate product reliability. For commercial or heavy-use garages, choose rugged builds and verify warranty terms.
Energy Efficiency And Operating Costs
Higher wattage increases heat capacity and operating cost. Select thermostatic control and ECO modes to reduce runtime and energy consumption. Match heater size closely to space needs to avoid unnecessary energy use.
