When the outdoor elements are less than favorable and you want to take your party to the garage, it helps to have a heater to increase the comfort level. Before making this move, you’ll need to determine whether you can use a patio heater in a garage.

Depending on the fuel source, not all patio heaters are suitable for indoor use. In fact, some are dangerous to use inside. Our guide can help you figure out which patio heaters are suitable for your garage, and which ones are better left outside.

The short answer is that it depends on the type of patio heater. A propane patio heater is definitely not safe to use in a garage since it requires open air or a well-ventilated area to prevent carbon monoxide poisoning.

However, an electric patio heater is safe to use in a garage so long as your electrical system can handle the power load the heater emits. You’ll want to check the specifications in the owner’s manual to ensure your garage heater doesn't blow a fuse or cause damage to your garage’s electrical system.

Which Heaters are Safe for Use in a Garage?

The most important factor to look for when purchasing or renting a heater for your garage is that it’s rated safe for indoor use. If you still have doubts, we highly recommend consulting a local heating specialist to determine whether it’s safe to move or install any type of heating system into your garage.

In most instances, electrical heaters are the safest type of heater to use in your garage. You can also look into a forced-air heater, or if you want a more permanent solution, consider installing radiant ceiling panels or a ductless mini-split system. 

How Do Patio Heaters Work? 

Depending on what type of patio heater you have, most work by using a source like gas, propane, or electricity to produce heat and push it through the outdoor air. They’re most often tall, standing units that you can move frequently or positioned in one spot. The type and number of patio heaters necessary will depend on the size of your space and whether it’s being used occasionally or year-round.

Common Types of Patio Heaters 

Patio heaters are not one-size-fits-all, which is great for homeowners who like to have options. In fact, they come in a variety of sizes and types to suit you and your outdoor needs. 

Propane 

Propane patio heaters use propane gas as their main fuel source. These types of portable heaters are best for large outdoor areas, such as campsites or patios, and come with an adjustable heat output. They’re also available in standing and tabletop models, depending on your needs. 

Electric 

As its name suggests, an electrical patio heater uses electricity to generate heat, so you’ll likely need an outdoor outlet or an extension cord in order to use one. They also tend to be more energy efficient but their range of heat is more limited than a propane heater. 

Natural Gas 

Less portable than the other options, natural gas heaters connect to your home’s main gas line and provide continuous heat. They come in standing units that are less portable because they have to remain connected to the gas line. They are often less expensive and easier to maintain than propane heaters.

Frequently Asked Questions

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.

It’s possible to install a garage heater yourself if it’s a portable model. However, more permanent garage heaters will require hiring a licensed electrician to run any electrical on larger units. You can also consult a local garage heating specialist to handle the entire installation from the start to finish to ensure it’s done safely and efficiently.
