Best Garage Space Heaters: Types and Features
When looking for the best garage space heaters, it’s essential to understand the different types available and their specific advantages. Here’s a breakdown of the main types of garage heaters to help you find the ideal option for your space.
Electric Garage Heaters
- Electric/Fan-Forced Heaters
Electric fan-forced heaters use electricity to power a fan that distributes warm air throughout the garage. These heaters are usually easy to install because they don’t require venting or a gas line. However, they can consume significant electricity, so a dedicated electrical circuit may be necessary. Many models of electric garage heaters are available, with varying features and heating capacities. Some models can be mounted on the wall or ceiling, while others are portable, making them versatile options among the best garage space heaters. - Radiant/Infrared Heaters
Electric radiant heaters warm objects and people directly rather than heating the air. This makes them efficient for spot heating rather than heating the entire space. Radiant heaters don’t have a fan, so they are quiet. They can be permanently installed or portable, depending on your needs. Consider these if you’re looking for quiet and efficient garage heaters. - Convection Heaters
Electric convection heaters, like oil-filled radiators, gradually heat the air through a heating element without using a fan, making them quieter than forced-air heaters. However, they may take longer to heat a garage compared to other types. If you’re prioritizing quiet operation, these can be some of the best garage space heaters to consider.
Gas Garage Heaters
- Natural Gas Heaters
Natural gas heaters often come with a fan to distribute heat effectively, making them ideal for large garage spaces. These heaters are cost-effective to operate but require professional installation and a gas line. If you’re heating a large garage, a natural gas heater may be the best garage space heater for your needs. - Propane Heaters
Propane heaters can be portable or permanently installed. They don’t require a gas line like natural gas heaters, but you’ll need to refill or replace the propane tank regularly. Some models of best propane garage heaters come with a propane conversion kit for added convenience.
Other Fuel Sources
- Kerosene Heaters
Kerosene heaters are known for quickly heating a space and can be more powerful than electric models. However, they may require more maintenance. Some kerosene heaters can also operate on diesel or heating oil, offering flexibility among the best fuel-based garage space heaters. - Wood-Burning Heaters
Wood-burning heaters create a cozy atmosphere and provide substantial heat but require a steady supply of wood and regular maintenance. For those who enjoy a rustic touch, these can be the best garage space heaters for warmth and ambiance.

What is the best type of heater for a garage?

How do I choose the right size garage space heater?
To choose the correct heater size, calculate the garage’s area and consider its insulation level. For electric heaters, use 10 watts per square foot of garage space. For gas heaters, 45 BTUs per square foot is a standard guideline.
What size gas heater do I need for my garage?

Where should a heater be placed in a garage?
For optimal performance, place a portable heater near the center of the garage, avoiding tight spaces. For mounted or fixed heaters, install them in the coldest corner of the garage, at least 24 inches away from walls or flammable surfaces, and direct the heat toward the center.
What safety considerations are important when using a garage space heater?
