Is it Safe to Use a Patio Heater in a Garage?

Garages often serve multiple purposes beyond housing vehicles. They can function as home gyms, art studios, extra storage, or even a cozy space for social gatherings. As more homeowners repurpose their garages, the question arises: Is it safe to use a patio heater in this enclosed area during the colder months?

While outdoor heaters are designed for open-air environments, using them in a garage requires careful consideration, especially when it comes to safety. In this article, we explore whether it’s possible to use a patio heater safely in a garage and the precautions you should take.

Electric vs. Gas Patio Heaters: Which is Safe for a Garage?

When considering a patio heater for garage use, it’s essential to understand the differences between electric and gas-powered models.

Electric Patio Heaters

Electric patio heaters are generally the safer option for enclosed spaces like garages. Since they don’t produce harmful emissions, such as carbon monoxide, they can be safely operated indoors. However, even with electric heaters, it’s crucial to maintain adequate clearance around the unit and keep flammable materials at a safe distance to avoid fire hazards.

Gas Patio Heaters

Gas heaters, including propane and natural gas models, pose more risks in enclosed spaces. They emit carbon monoxide, which can build up if the area lacks proper ventilation. Bromic does not recommend using gas-powered in any enclosed or semi-enclosed spaces as they require ample airflow to allow any harmful gasses to escape. 

Can I Use a Patio Heater in My Garage with the Door Open?

The short answer is, yes. The open door allows for proper ventilation, helping to prevent dangerous carbon monoxide buildup. However, it’s still essential to keep an eye on the heater to ensure it operates safely, with sufficient clearance to avoid fire hazards.

Other Areas Where You Can Use a Patio Heater

Outdoor patio heaters are incredibly versatile and designed for open or semi-enclosed spaces. They’re ideal for areas like covered patios, decks, outdoor dining areas, lounges, gazebos, and screened-in porches. These locations allow for adequate ventilation while providing warmth and comfort.

Final Verdict

We advise against using gas-powered patio heaters in enclosed spaces like garages due to the risk of carbon monoxide poisoning. If you do wish to heat your garage, electric patio heaters are a safer alternative. For further guidance, refer to our Installation Manuals or consult with a licensed electrician to ensure the setup is safe. Bromic offers a range of electric outdoor heaters that deliver both style and performance in semi-enclosed spaces.
