Garage Heater Cost Factors
The average cost of a garage heater is around $2,075, but the costs can range widely from around $150 for a small electric heater that you install yourself to $4,000 for larger units installed by HVAC professionals.
Electric and infrared heaters tend to cost less, around $150 to $1,000. Natural gas and propane garage heaters range from around $400 to $2,000.
A 30,000 BTU heater costs about $0.28 to $0.80 per hour to run. BTUs, or British Thermal Units, measure energy. Most two-car garages need a 45,000 BTU heater for efficient heating, while three-car garages need 60,000 BTUs.
Garage heater installation costs about $100 per hour. For propane or natural gas heaters, the pros may add another $500 to $800 due to the dangers of working with gas lines. It should take about two hours to install the garage heater.
A garage heater costs about $0.08 to $0.80 per hour or $2 to $19 per day to run. You may only run your heater while you are in the garage, or you might install a heater that runs continuously. The longer your heater is running, the higher the bill will be.
Garage Heater Costs by Type of Fuel
The energy source your heater requires can also impact the cost of garage heaters, with costs starting around $150 for simple electric heaters to $2,000 for propane or gas heater units.
Electric heaters range from $150 for small heaters that you can set up on your own with little trouble to over $1,000 for larger options that may require a professional to install.
A propane garage heater will cost around $400 to $2,000, not including cost of installation. While this is a good option if you want a gas heater but don’t have a natural gas line to your home, be aware of the risks of using propane heaters.
Natural Gas Heater
Natural gas heaters, which range from $400 to $2,000 are usually the most efficient options for a garage. Installation costs for this type of heater can be more expensive compared to electric or infrared, because working with gas lines can be dangerous.
An infrared heater, which costs $400 to $800, converts electricity into radiant heat. This is a good option if you want a balance of a lower cost and higher efficiency. Infrared heaters can save 30% to 40% more energy than other electric heaters.
What Garage Heater Can I Get on My Budget?
Here are four price ranges to consider when shopping for a new garage heater.
Basic electric garage heaters for one or even two-car garages can be found for under $200. These easily fit on a shelf or bench and keep your small garage warm.
If your budget is under $100, you might consider just using an electrical space heater if your garage is small and at least somewhat insulated. Just be sure to keep it clear of walls and other obstructions for efficient airflow and safety reasons.
Two and three-car electric garage heaters are available for under $300. You may be able to save $50 or $100 by shopping at the end of cold-weather seasons for the newest models, or looking online for deals.
Between $300 and $400, you’ll be able to find an electric garage heater for nearly any size garage. Some propane-powered models are also available starting around $350.
Propane, infrared, and gas-powered garage heaters are available in this price range. Because they’re more difficult to install, you may have to factor in several hundred (or even a thousand) extra dollars for installation.
Natural gas garage heaters start around $450. For large garages or high-powered units (60,000+ BTUs), you may pay $1,000+ for the unit alone.
Garage Heater Cost Breakdown
The cost to install a garage heater can be separated into two main factors: the cost of the heater unit itself and the cost for labor. Most professionally installed heaters will cost around $2,075.
A garage heater costs around $150 to $2,000 depending on the fuel type and BTUs. Other materials needed to install a heater can vary. For example, an electric space heater can just plug into the wall, or you may need a drill to mount a wall or ceiling heater.
You’ll spend about $100 per hour, a total of around $200, for garage heater installation. Propane and natural gas garage heater installation may cost an additional $500 or more.
Cost to Install a Garage Heater Yourself
You can install electric or infrared heaters for about $150 to $1,000 by going the DIY route. But when it comes to natural gas or propane heaters, don’t attempt installing these alone. Instead, hire a local HVAC specialist to safely and properly handle the gas lines and install these types of garage heaters.
Tips to Reduce the Cost of a Garage Heater
Aside from shopping for heaters in the middle of summer, there are some things to keep in mind if you want to lower your costs.
Insulation: Make sure your garage is well-insulated, so you aren’t using more energy for the heater than necessary.
BTUs: Choose a heater with BTUs sufficient for your space. A two-car garage needs about 45,000 BTUs.
Size: If you don’t spend a lot of time in the garage, you can save money by opting for a small, portable heater.
Which type of heater is best for a garage?
You’ll pay the most for setup, but gas heaters are the most efficient of the bunch. It does depend how warm you need the area and if you’ll be using the whole garage or just want to warm a small section, though. An electric heater could easily meet your needs if you’re just working in a small corner or have a small garage.
Are garage heaters expensive to run?
Garage heaters can cost anywhere from $2 to $19 a day to run, depending on the type of heater and how often you’re running it.
Are garage heaters worth it?
If you enjoy tinkering with cars, woodworking, or exercising in your garage, then a garage heater may be worth it to you. If your garage is used mainly for storage, you may opt to skip installing a garage heater. If you live somewhere with favorable weather year-round, you can probably go without one as well. But for most homeowners, a garage heater is a good investment and makes the garage a more comfortable place to spend time.
What are some low-cost ways to heat a garage?
If you don’t spend much time in the garage, you might just bundle up when it’s time to dig through storage containers for winter holiday decor. You may also consider a space heater for smaller garages. Another great way to keep the garage warm is to improve the wall insulation to keep the cold air out.
