For anyone who spends considerable time in their garage, whether for car repairs, woodworking, or simply tinkering, a garage heater isn’t just a luxury—it’s a necessity, especially during the colder months. Garage heaters are designed to combat the chill and create a comfortable working environment, much like space heaters but with the power to warm larger, often less insulated spaces. Choosing the right garage heater depends on several factors, including the size of your garage, your local climate, and how you intend to use the space.
To help you find the best solution for your needs, we’ve rigorously tested a variety of garage heaters, from gas-powered to electric models. We evaluated each heater based on setup ease, heating performance, and key features. We also consulted with industry experts like Traci Fournier, Vice President of Operations at One Hour Heating & Air Conditioning, to bring you professional insights on selecting the ideal garage heater.

Key Factors to Consider When Choosing Best Rated Garage Heaters
Selecting the right garage heater involves more than just picking a top-rated model. Here are crucial factors to consider to ensure you choose the best heater for your specific needs:
Type of Garage Heater
Garage heaters primarily come in two main types: gas and electric.
- Electric Heaters: These are generally easier to install, requiring only plugging into an electrical outlet. Infrared electric heaters are a subset known for their energy efficiency, as they heat objects directly rather than the air.
- Gas Heaters: Often more cost-effective to run, gas heaters can be natural gas (requiring a gas line installation) or portable models that use propane, kerosene, or diesel. Gas heaters necessitate good ventilation to prevent carbon monoxide buildup.
Garage Size and Heating Capacity (BTUs/Watts)
The size of your garage directly impacts the heater size you’ll need. A general guideline is to estimate 10 watts of heating power for every square foot of garage space, as recommended by expert Traci Fournier. For example, a 20×24 foot garage (480 square feet) would require approximately 4,800 watts of heating power.
BTU (British Thermal Units) is another common measurement, particularly for gas heaters, indicating the amount of energy needed to produce heat. Higher BTU ratings mean more powerful heating.
Power Source and Fuel Type
Consider the available power sources in your garage and the ongoing fuel costs.
- Electricity: Convenient if you have sufficient electrical outlets and amperage. Electric heaters can be more expensive to operate depending on local electricity rates.
- Propane, Natural Gas, Kerosene, Diesel: Gas heaters can be cheaper to run but involve fuel procurement and storage (for portable models) or gas line installation (for natural gas). Ventilation is critical for fuel-burning heaters.
Installation Requirements
Installation can range from simple plug-in portability to complex hardwiring or gas line setups.
- Portable Heaters: Require minimal setup, often just connecting to a propane tank or plugging into an outlet.
- Ceiling or Wall-Mounted Heaters: Electric models may need hardwiring, requiring professional electrician services. Natural gas heaters necessitate gas line installation, also best left to professionals.
Professional installation ensures safety and optimal performance, minimizing risks of malfunction or hazards associated with DIY installations, as emphasized by Traci Fournier.
Safety Features
Safety is paramount, especially in a garage environment. Look for heaters with:
- Overheat Protection: Automatic shut-off if the heater gets too hot.
- Tip-Over Shut-Off: Essential for portable heaters to prevent accidents.
- Cool-Touch Exterior: Reduces burn risks, especially important if children or pets are present.
- Carbon Monoxide Detection: For gas heaters, ensure proper ventilation and consider a CO detector as a backup safety measure.
Additional Features
Extra features can enhance convenience and efficiency:
- Thermostat: Allows precise temperature setting and automatic temperature maintenance.
- Remote Control: Convenient for adjusting settings from a distance, especially for ceiling-mounted units.
- Timer: Programmable timers for automatic on/off cycles, saving energy and ensuring warmth when needed.
- Wi-Fi Connectivity: Smart features for remote control via smartphone apps and integration with smart home systems.
- Energy-Saving Modes: Eco modes or variable heat settings to optimize energy consumption.
Budget
Garage heater prices vary widely based on type, power, features, and installation needs. Portable electric heaters can start around $50-$100, while larger, more powerful models or professionally installed units can cost several hundred dollars or more. Factor in fuel costs for gas heaters and installation fees for hardwired or gas line installations when budgeting.
Frequently Asked Questions About Best Rated Garage Heaters
What is the most efficient type of heater for a garage?
Gas heaters are often considered more energy-efficient in terms of fuel cost versus heat output, especially for larger garages. However, modern electric infrared heaters with features like thermostats and eco-modes can also be very efficient, particularly for targeted heating or smaller spaces. The “most efficient” type depends on garage size, insulation, and local energy costs.
How many BTUs are necessary for heating a two-car garage?
For an average two-car garage (500-700 square feet), around 45,000 BTUs is generally recommended. However, this can vary based on insulation levels, climate, and desired temperature increase. Use the 10 watts per square foot rule as a starting point and adjust based on specific garage characteristics.
How much does it cost to install a garage heater?
Installation costs vary significantly. Portable heaters have minimal to no installation costs. Hardwiring an electric heater might range from $100 to $300 or more, depending on electrician rates and complexity. Natural gas line installation can be considerably more expensive, potentially ranging from $500 to over $1,000, depending on the distance to the gas main and local labor costs. Always get quotes from qualified professionals for accurate estimates.
Other Garage Heaters We Tested
While the above models topped our lists, we also tested other garage heaters that, while not top picks, still offer valuable features:
Heat Hog 18,000 BTU Indoor/Outdoor Portable Propane Heater
The Heat Hog Portable Propane Heater is compact and offers directional heating with its tilting design. While suitable for small garages up to 450 square feet, its propane consumption is relatively high for its size. It may be better suited for outdoor use like camping or tailgating where portability is highly valued.
Remington REM-80T-KFA-O Kerosene/Diesel Forced Air Heater with Thermostat
The Remington REM-80T-KFA-O is a powerhouse, delivering up to 80,000 BTUs and rapidly heating large garages even in very cold conditions (tested at 4°F). Its kerosene or diesel fuel source demands excellent ventilation due to carbon monoxide risks. This heater is for those prioritizing rapid, intense heat in large, well-ventilated spaces and are comfortable managing fuel-powered devices.
Our Testing Process
Our recommendations are based on rigorous testing of various garage heaters. We evaluated portable, freestanding, infrared electric, and gas-powered models. For hardwired models, we ensured professional electrician installation.
Our testing methodology included:
- Setup and Baseline Measurement: Setting up each heater in a garage environment with ventilation, placing a thermostat 10 feet away, and recording baseline temperature for an hour before heating.
- Performance Evaluation: For the first three uses, we recorded temperatures before heating, after 15 minutes, and after daily use. We also noted outside temperature, weather conditions, and garage contents (number of vehicles).
- Safety Assessment: Evaluating safety features such as timers, tip-over auto-off, exterior temperature, and overheat protection.
- Feature Testing: Assessing additional features like thermostats, timers, humidity sensors, and eco modes.
- Usability Factors: Considering noise levels, ease of operation (on/off), and portability for relevant models.
- Energy Consumption (Electric Models): Monitoring energy bill changes and consumption during the testing period for electric heaters.
This comprehensive testing process allowed us to objectively assess each heater’s performance, safety, and usability, ensuring our recommendations for the best rated garage heaters are reliable and helpful.
