There are several reasons why your garage may be cold in the winter: drafty garage doors, concrete floors, and poor insulation, to name a few. The good news is that you'll no longer need to bundle up before entering your garage, workshop, or shed this winter. With an electric garage heater, you can spend time in your garage without chattering teeth and cold fingers. 

To help you find the right heater for your space, we've rounded up the best garage heaters on the market. Before we dive into our reviews of the best electric garage heaters, let's take a quick look at what you need to know before purchasing a heating unit for your home. 

What To Consider When Shopping For a Garage Heater

Heating Capacity

The dimensions of your garage significantly influence the required heating capacity. Measure the square footage of your space, as different heaters are designed to handle various sizes. Overly powerful heaters may be unnecessary and costly to run in smaller garages, while underpowered ones may struggle to warm larger spaces adequately. Matching the heater's output to your garage's dimensions is essential for optimal performance.

Heating Type

The main difference between the different types of garage heaters is that they use various power sources to create heat. While each has pros and cons, most homeowners opt for electric space heaters that do not require natural or propane gas. Here are the different types of garage heaters:

Electric Heaters: Electric heaters are favored for their simplicity and effectiveness. They are commonly either wall-mounted or portable, relying on electricity for heat production. These heaters are well-suited for smaller to medium-sized garages and do not necessitate ventilation. They operate quietly and distribute heat evenly, although their long-term operational expenses might be higher.

Propane Heaters: Propane heaters offer versatility and portability. They run on propane fuel, making them suitable for areas without electricity or natural gas access. These heaters are often used in workshops or outdoor spaces and can heat medium-sized garages effectively. Adequate ventilation is a necessary requirement when utilizing propane heaters.

Natural Gas Heaters: Opting for a natural gas heater proves cost-effective and efficient when your garage is connected to a natural gas line. These heaters are usually wall-mounted or ceiling-mounted and can heat larger spaces. They require professional installation and proper ventilation.

Kerosene Heaters: Kerosene heaters, known for their potency and portability, are well-suited for heating expansive spaces. They run on kerosene fuel and do not require electricity. However, they need adequate ventilation and fuel storage considerations.

Forced Air Heaters: Forced air heaters, often powered by propane or natural gas, blow warm air into the garage using a fan. These heaters can efficiently warm large areas and are frequently employed in industrial and commercial settings. Proper ventilation is crucial with these heaters.

Infrared Garage Heater: Infrared heater directly emits heat, creating a localized heat source that is ideal for small spaces, as they don't contain a fan to circulate the warmed air.

Safety Features

When seeking a garage heater, prioritize safety features. Opt for models featuring tip-over protection, an automatic shut-off mechanism that activates if the heater is inadvertently knocked over. This enhances safety by minimizing the risk of fires or burns. Overheat protection is crucial, as it prevents the unit from reaching dangerously high temperatures that can lead to malfunctions or hazards. Verify that the heater has proper ventilation requirements and clearances to prevent carbon monoxide buildup and potential combustion. Check if the product complies with industry safety standards and local building codes. Choosing a garage heater with robust safety features ensures a secure and worry-free heating solution for your workspace.

Installation

Consider your garage's layout and available space when deciding between ceiling-mounted and wall-mounted units. Ceiling-mounted heaters can save floor space and provide more even heating, while wall-mounted units may be easier to install and access for maintenance.

Watts

When shopping for a garage heater, pay close attention to its wattage, as it directly impacts heating performance. Take into account the dimensions and insulation of your garage. Smaller or well-insulated spaces may require lower-wattage heaters (around 1,000-2,000 watts). In comparison, larger or poorly insulated garages may need higher wattage units (3,000 watts or more) to maintain a comfortable temperature. Efficient models with adjustable wattage settings enable you to customize the heat output according to your requirements, providing versatility and potential cost savings. Ultimately, selecting the appropriate wattage ensures efficient and effective heating, keeping your garage comfortable during cold seasons without unnecessary energy consumption.

Budget

Set a realistic budget for your garage heater purchase. Prices can fluctuate significantly, emphasizing the importance of striking a balance between desired features and budget constraints. It's worth noting that while a pricier heater may offer advanced features, a more affordable option can still effectively fulfill your heating requirements.
