To get the best experience outdoors in the shoulder season and the winter, we all know how helpful a patio heater can be. A simple patio heater can be the difference between unseasonably cold and comfortable. But what if it’s a little too cold in your house? What if your garage is just a little too cold and you want to take the edge off? Can you use a patio heater indoors? In this article we will examine why you want to avoid it, and when it might be okay.
Can You Use A Patio Heater Indoors?
First, if you have a gas or propane powered patio heater, never use it indoors. Let me reiterate that. Never use a gas or propane patio heater indoors at any time. Much like using a propane portable grill indoors, there are numerous ways you can destroy property, injure yourself or others, and even cause death.
Propane and natural gas patio heaters give off carbon monoxide which is a tasteless and scentless gas. This will cause you to lose consciousness in areas which are not properly ventilated. There are risks of the heater igniting the ceiling above the heater, there are risks of the heater falling over, and of course risks of the propane being left on and the propane itself being a danger.
Propane can explode, and propane can also kill through inhalation of propane gas. Unlike natural gas, propane will flow to the bottom of the room. If you have a propane leak on the first floor, it can flow down the stairs and fill up the basement. Suffice it to say, do not use your gas or propane patio heater indoors.

Propane/Natural Gas vs. Infrared Patio Heaters
Thankfully, since infrared heaters do not use propane/natural gas to create heat they don’t have an explosive risk. They have a far less likely fire risk as well, given their heat is produced with infrared radiation. There is still a fire risk with an infrared heater. Make sure you don’t have any combustibles like paper, styrofoam, or plastics within the distance outlined in the owner’s manual. It’s highly unlikely, but still possible for an infrared heater to start a fire because it’s too close to combustible substances.

If your heater is not designed for use indoors, we’d recommend not risking it. Infrared heaters have gotten so much less expensive, we’d recommend buying a heater solely for indoor use. They are usually a bit more attractive than the indoor / outdoor models. But if aesthetics aren’t a concern, an indoor / outdoor model can give you the flexibility of owning a single heater with multiple use case options.
Whenever you are using an electric infrared heater, make certain you have your electrical wiring up to code. These heaters have become more and more efficient over the years. However, they still draw some serious current and this can cause problems for antiquated electrical systems.
