Patio Heater Power and Fuel Sources
When the temperatures drop and a chill is in the air, having a source of outdoor heat will make outdoor activities more enjoyable. Patio heaters are well suited to northern climates, where the mercury plunges as soon as the summer sun drops beneath the horizon. They’re also beneficial in warmer regions, day or night, during the winter months. When shopping for the best outdoor heater, you have several options for the type of power required to operate the unit.
Propane patio heaters can warm up spaces quickly. Some are quite large and will hold up to a 20-gallon propane tank—a boon when you wish to heat a large area for an extended period. These outdoor heaters are often portable, depending on the style, and many include wheels.
Due to the risk of carbon monoxide buildup, don’t use exterior propane heaters in an enclosed area, such as a greenhouse or enclosed patio, unless a clear safety feature is built into the unit to prevent operation under insufficient oxygen levels.
Gas heaters fueled by natural gas are more likely to be considered permanent fixtures on the patio than propane heaters because they connect to a home’s natural gas line. Depending on local building codes, running a natural gas line to the patio probably requires the services of a licensed plumber.
The upside to a natural gas patio heater is a lower operating cost because natural gas is usually a less expensive power source than propane. If you’re looking for a reliable source of patio heat, a natural gas heater could be a cost-effective way to entertain outdoors, even during cool weather.
There’s no need to buy fuel for electric patio heaters, but plan to replace the heating lamps occasionally. With no open flame, electric heaters may be safer than other types for some families. But they are usually smaller and not as powerful, so an electric patio heater may not generate as much heat as its propane cousin.
When shopping for an electric patio heater, compare the heat output of different models, but keep in mind that a higher heat output means increased electricity usage and a larger electric bill. Also, remember that the best electric patio heater includes a power cord, so it’s necessary to have at least one outdoor electrical outlet.
For an authentic campfire feel, there’s nothing quite like a wood-burning patio heater. This type of heater can generate a lot of heat, depending on the size of the firebox and the amount of wood it will hold.
Since wood fires can create smoke and ash, a wood-burning patio heater isn’t suitable for an enclosed patio. To reduce smoke, burn only seasoned hardwoods, such as hickory, birch, and white ash. Some communities don’t permit open firepits, so check with your local fire department before buying one.
What to Consider When Choosing the Best Patio Heater
Some patio heaters are large and serve as a focal point on the patio around which merrymakers gather, while others are strictly functional—they heat the area but don’t add much in the way of ambiance. Choosing the outdoor heating option that best suits a specific patio is mostly a matter of individual taste, but a few factors are worth considering.
Just because it’s a patio doesn’t mean this outdoor space shouldn’t receive the same decor attention as any indoor room. A variety of patio heater styles can add a unique aesthetic to a backyard oasis.
- Tower-style heater: Most tower-style patio heaters are 6 to 8 feet tall, with the heat source located at the top, middle, or bottom of the tower. Available in electric or propane versions, these patio heaters can warm a 5- to 10-foot radius, making them an excellent option for yards and larger patios.
- Space heater: More about function than aesthetic, an exterior space heater is relatively small and designed to heat a limited space. For outdoor dining, a space heater tucked beneath the patio table may be sufficient to keep diners cozy as they enjoy a meal. Space heaters may be powered by propane or plugged into an outdoor electrical outlet.
- Tabletop heater: Smaller than freestanding heaters, tabletop units are often secured to a patio table (usually through the hole where a sun umbrella would fit). Either electric or propane, they offer the advantage of portability but tend to be less powerful, making them well suited to smaller gatherings.
- Mounted heater: Available in wall- or ceiling-mounted options, these patio heaters are typically infrared (they radiate heat) and are electrically powered. They are excellent if you have limited floor space but wish to heat a large area.
- Firepit/fireplace: Perhaps the ultimate in outdoor ambiance, firepits, and outdoor fireplaces offer the type of flickering ambiance associated with a campfire, so it’s little wonder that they’re high on many outdoor entertaining wish lists. They may be powered by propane, natural gas, or wood and are ideal for being surrounded by patio chairs for a late-night s’mores session.
The maximum area a patio heater will comfortably heat depends on several variables. Many large patio heaters are radiant, meaning they reflect heat waves rather than distribute heat via a fan. Radiant heat is more effective because it warms objects in front of it rather than just warming the air. On a breezy day, a fan-based heater (convection) won’t keep anyone warm if the wind blows away the heated air.
Depending on the power of the heating element, a patio heater can radiate heat 4 to 12 feet or even farther. Many feature the ability to adjust the heat output—turning down the heater if only a bit of warmth is necessary or running it on the highest setting to heat a wider area.
A natural gas or propane patio heater’s heat output is measured in British thermal units (BTUs), while an electric heater’s output is measured in watts.
- BTU estimation: The general formula for estimating suitable BTUs for a patio heater is to multiply the patio’s square feet by 20. For example, a patio that measures 20 by 20 feet equals 400 square feet of space. Multiplying 400 by 20 is 8,000, so a gas patio heater with an 8,000-BTU output would effectively heat the area. Gas patio heaters range from about 5,000 to 40,000 BTUs, depending on style and size.
- Watt estimation: Electric patio heaters offer a maximum of 1,500 watts—comparable to 5,100 BTUs—so they don’t generate quite as much heat as gas heaters, making them well suited to smaller patios. Alternatively, consider using two or more electric patio heaters on a single patio if you desire additional heat output.
While the main function of a patio heater is to maintain a comfortable outdoor temperature, many go the extra mile to help create a cozy or romantic feeling. Some tabletop styles incorporate glass rocks that reflect various light colors, while others produce flickering flames that add a dreamy feel.
Except for the smallest space heaters, most propane patio heaters feature a cabinet that conceals the propane tank to create a cleaner look. For the best aesthetics, select a material that blends with the style of the home and patio. A sleek stainless steel patio heater will enhance the look of a contemporary home with modern décor, while a cast-iron firepit would better suit a rustic cabin getaway.
Anything that produces enough heat to warm a patio comes with some safety challenges. Manufacturers reduce the risk of burns by encasing patio heaters in materials that remain cool to the touch or placing the heating element above a level where humans can reach it (in the case of tower-style heaters). Still, consider the following tips to more safely use a patio heater.
- Move it away: Keep the patio heater away from walls, patio furniture, and flammable objects. The general rule is to position a patio heater with 3 feet of space on all sides.
- Keep it level: Some patio heaters provide a safety shutoff if the heater tips, but not all include that feature. Position the heater on a level spot to keep it from tipping over.
- Buy a fire extinguisher: Patio heaters don’t present a significant fire risk, but a wood-burning heater can eject burning ash, or a space heater could tip over. By having an extinguisher handy, you’ll be prepared in case of fire.
- Stay with it: Don’t leave a patio heater on without an adult present.
- Keep it covered: Some patio heaters include a cover. If not, invest in one, and cover the patio heater when not in use. A cover will keep bugs, dirt, and debris from blowing into the heating element, which can clog it or create a fire risk.
The ability to move a patio heater from one side of the patio to the other or relocate it near a pool will be simpler if the unit includes wheels.
The largest propane patio heaters can weigh 60 pounds or more—and that’s not including the weight of a 20-pound propane tank—so carrying one can quickly become cumbersome. Electric patio heaters are typically smaller and more lightweight, weighing up to an average of 20 to 30 pounds, but wheels will still come in handy.
The smallest portable heater may weigh only a few pounds and easily be packed in the trunk of a car or moved to any yard location.
When it comes to electric patio heaters, the real cost often comes in paying the utility bill because electricity is usually (not always) more expensive than either natural gas or propane. That said, electric heaters are a less expensive option.
Propane patio heaters run the gamut in price from inexpensive space heaters to tall tower-style heaters, but operating them is generally more cost-effective than electric models.
Natural gas patio heaters are often at the top of the price line because they are frequently designed for installation in permanent outdoor kitchens and living areas. They’re among the least expensive to operate, but you may require a licensed plumber for installation.
Wood-burning firepits and fireplaces also span a large range in cost, from inexpensive firepits to high-end fireplaces permanently built into outdoor entertaining areas.
