Best Patio Heaters

Whether you’re hoping to keep patio parties going late into the night or to extend backyard barbecue season, patio heaters are your best friend. These handy heaters warm up the space around them, making outdoor living spaces more comfortable on chilly evenings or cool fall days. Today’s homeowners are “using their outdoor spaces more and extending usage earlier in the spring and later in the fall,” says design expert Tim Bakke. In the fall we saw “a run on patio heaters to the point where they were almost impossible to get.” Suffice it to say, this trend is hot.

There are many styles of patio heaters to choose from, with the most popular being the mushroom-shaped models you frequently see on restaurant patios. However, you can also find pyramid-shaped, wall-mounted, and even tabletop patio heaters, as well as options powered by propane, natural gas, and electricity. For optimal safety, opt for a patio heater with features like a CSA safety rating, a tilt-proof design, and an automatic gas shutoff (for windy days).

Here, the best patio heaters you can buy today.

What to Look for in a Patio Heater

Power Source

Patio heaters are available with a variety of fuel or power source options. Propane is the most popular fuel source for a patio heater, but if you don’t want to deal with propane tanks, then an electric-powered patio heater may be a better fit. Electric patio heaters can typically be plugged into standard residential outlets, but make sure they’re protected from the elements to avoid electrical hazards or malfunctions.

Range

Are you looking for a personal-sized patio heater that will keep you and a friend or two warm or a larger unit that can heat things up for a small crowd? Larger patio heaters generally have a greater range—up to 18 feet or more—while small, tabletop models will only radiate heat for a distance of a few feet.

Heat Output

The intensity and effectiveness of a patio heater is likely best evaluated by its heat output. This is generally measured as BTUs for gas-burning patio heaters and watts for electric heaters, and the average output for patio heaters is 40,000 BTUs. To compare how well two units will heat your space, compare the BTUs or watts of each model to find the one that will fit your temperature preferences and space.

FAQ
  • How do I choose the right fuel source?

    There are three common fuel sources for patio heaters: liquid propane, natural gas, and electricity. To figure out which is right for you, think about what’s most readily available, convenient, and affordable.

    Many heaters are powered by 20-pound liquid propane tanks, as the fuel is quite affordable, but you’ll have to refill your tank, which typically entails taking a trip to a local convenience store, gas station, or home improvement store. If that sounds like a hassle, you may want to opt for an electric model, which simply plugs into a standard 120-volt outlet. Just be aware that frequent use of an electric patio heater may increase your electricity bill. Natural gas is another option, but it's only practical if you already have a natural gas line installed in your home. 

  • What are BTUs?

    You’ll often see the heat output of patio heaters quantified in BTUs, or British thermal units, which is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. A good patio heater can typically produce a maximum of 30,000-50,000 BTU per hour—the higher the number, the faster it will be able to warm up a large area. 

  • How do I clean a patio heater?

    A few times per season, you may want to wipe down the exterior of your patio heater using soapy water to remove any dirt or blemishes. You can keep your patio heater clean by covering it when not in use and storing it properly during the off-season.

    It’s also a good idea to occasionally check the unit’s pilot tube and thermocouple for corrosion or damage, as well as the fuel regulator and fuel line for kinks, breaks, or leaks. If any of these parts are damaged, you’ll need to consult the owner’s manual for directions on how to replace them. 

  • Where should I place my patio heater?

    When setting up your patio heater, it should be placed on a flat, solid surface to minimize the risk of tipping. You’ll also want to keep it at least three feet away from combustible items like plants, fabrics, and even propane tanks. In general, arrange the heater fairly close to your outdoor seating or dining area—this will allow you to get the most heat from it, and if it’s too warm, you can simply turn it down, which will also help you save fuel. 

  • Are patio heaters safe on decks?

    Because the base of a freestanding patio heater won't get hot from the radiated heat, most patio heaters are safe to use on wooden decks (as long as they aren't left unattended). With that being said, it’s always a good idea to double-check the instruction manual to be sure.
