Dr. Infrared DR-218
Best OverallPros
- Quiet operation
- Dual heating technology
- Safety tip-over switch
Cons
- Heavy for wall mount
- Fan noise on high
The Dr. Infrared DR-218 uses a dual heating system that combines infrared and convection to warm the room evenly without drying out the air. Owners report it heats a standard two-car garage quickly and maintains temperature well. The unit includes a programmable thermostat and multiple safety features.
While it is heavier than some competitors, the build quality is solid. Some users note the fan can be audible on the highest setting, but for most garage applications this is not a dealbreaker. It is a reliable choice for consistent, whole-garage warmth.
NewAir G56
Best Budget Wall HeaterPros
- Compact and sleek design
- Easy wall installation
- Adjustable thermostat
Cons
- Limited coverage area
- No remote control
The NewAir G56 is a hardwired wall heater that provides efficient supplemental heat for smaller garages or workshops. It features a fan-forced design that circulates warm air quickly, and the thermostat allows for precise temperature control. Owners appreciate its low profile and how it frees up floor space.
It is best suited for insulated garages up to 500 square feet. In larger or drafty spaces, it may struggle to maintain temperature. For the price, it offers excellent value and reliable performance for targeted heating needs.
Mr. Heater MH60QFAV
Best for Large GaragesPros
- High BTU output
- Dual fuel capability
- Durable construction
Cons
- Requires professional installation
- Needs ventilation
The Mr. Heater MH60QFAV is a powerful forced-air garage heater designed for large, uninsulated spaces. It can run on either propane or natural gas, giving you flexibility depending on your setup. Owners report it can quickly raise the temperature in a three-car garage or large workshop.
Because it is a gas heater, it requires proper ventilation and professional installation to ensure safety. The unit is built to last, but the initial setup cost is higher than electric models. For those with big heating needs, it is a workhorse that delivers consistent results.
Dyna-Glo RMC-95C1DG
Best Portable KerosenePros
- Extremely high heat output
- Portable with wheels
- Quick heating
Cons
- Kerosene odor
- Requires ventilation
The Dyna-Glo RMC-95C1DG is a portable forced-air kerosene heater that delivers massive heat for large, open areas. It is ideal for construction sites, barns, or very large garages where a permanent heater is not feasible. Owners praise its ability to heat a space in minutes.
The main drawbacks are the smell of kerosene and the need for adequate ventilation to avoid fumes. It is not suitable for enclosed, occupied spaces without fresh air. For temporary or spot heating in well-ventilated areas, it is an effective and powerful tool.
Stiebel Eltron CK 15E
Best Compact ElectricPros
- Very compact and lightweight
- Easy to mount
- Quiet fan
Cons
- Limited coverage
- No built-in thermostat
The Stiebel Eltron CK 15E is a small, wall-mounted fan heater that is perfect for a small workshop or a single bay of a garage. It is designed for supplemental heat and works best in well-insulated spaces. Owners like its unobtrusive size and quiet operation.
It does not have a built-in thermostat, meaning you have to manually turn it on and off. For a small area that needs quick bursts of heat, it is a reliable and affordable option. It is not designed to be the primary heat source for a large space.
What to check before buying a garage heater
First, measure your garage's square footage and check the insulation level. A well-insulated space needs fewer BTUs. For electric heaters, ensure your circuit can handle the amp draw, especially for 240V models. For gas or kerosene heaters, plan for proper ventilation and fuel storage.
Consider the heater's safety features like tip-over switches, overheat protection, and cool-touch exteriors. Also, think about the mounting options. Wall or ceiling-mounted units save floor space, while portable models offer flexibility. Finally, check the noise level if you plan to work in the garage while the heater is running.
Mistakes to avoid
One common mistake is buying a heater with too low a BTU rating for the space, which will run constantly and never fully warm the garage. Another is ignoring ventilation requirements for gas or kerosene heaters, which can lead to dangerous carbon monoxide buildup. Always follow the manufacturer's safety guidelines.
Also, avoid placing heaters too close to flammable materials like paint, solvents, or cardboard boxes. Do not use extension cords with high-wattage electric heaters unless the cord is rated for the load. Finally, do not forget to check the warranty and return policy before purchasing.
FAQs
What size garage heater do I need?
Calculate the square footage of your garage and multiply by 10 to get the approximate BTUs needed for a well-insulated space. For uninsulated garages, increase that number by up to 50%.
Can I use a kerosene heater in my garage?
Yes, but only in well-ventilated areas. You must open a door or window to prevent carbon monoxide buildup. Never use a kerosene heater in an enclosed space without ventilation.
Are electric garage heaters safe?
Yes, modern electric heaters include safety features like tip-over switches and overheat protection. They produce no fumes, making them safer for enclosed spaces than gas or kerosene models.
How many BTUs do I need for a 2-car garage?
A typical 2-car garage is about 400 to 500 square feet. For an insulated garage, you would need around 4,000 to 5,000 BTUs. For an uninsulated one, look for 6,000 to 8,000 BTUs.
Can I leave a garage heater on overnight?
It is not recommended to leave any space heater unattended for long periods. If you need overnight heat, consider a heater with a built-in thermostat and safety shut-off, and ensure it is clear of obstructions.
What is the difference between infrared and convection heaters?
Infrared heaters warm objects and people directly, providing instant heat. Convection heaters warm the air, which then circulates to heat the room. Infrared is better for spot heating, while convection is better for whole-room warmth.
Do I need a 240V or 120V garage heater?
120V heaters are easier to install and work with standard outlets, but they are limited to 1,500 watts. 240V heaters provide more power and are better for larger spaces, but they require a dedicated circuit and professional installation.
How do I install a wall-mounted garage heater?
Most wall-mounted heaters come with a mounting bracket. You need to secure the bracket to wall studs, then hang the heater. For hardwired models, you will need to connect the wiring to a dedicated circuit, which is best done by a licensed electrician.
What is the best fuel type for a garage heater?
Electric is the safest and easiest for most homeowners, especially for smaller garages. Propane and natural gas are more powerful and cost-effective for large spaces, but they require ventilation and professional installation.
How do I maintain my garage heater?
For electric heaters, keep the vents clean and free of dust. For gas or kerosene heaters, clean the burner and fuel lines regularly. Always follow the manufacturer's maintenance schedule for optimal performance and safety.
Our verdict
For most homeowners, the Dr. Infrared DR-218 offers the best combination of efficiency, safety, and coverage for a standard garage. If you are on a budget or need a permanent wall heater for a smaller space, the NewAir G56 is a fantastic value. For large, uninsulated garages, the Mr. Heater MH60QFAV is the most powerful option.
