Homeowners have begun expanding their living space into the backyard through large, inviting patios complete with outdoor kitchens and dining areas. These are real investments into the home and can provide terrific spaces for entertaining, so it makes sense to weatherproof those areas so they can be enjoyed year-round.

One way to ensure families and guests stay warm in the winter months while still enjoying the great outdoors is to use patio heaters that operate by radiating warmth within a set radius of the heaters.

But choosing the right patio heater for your environment is crucial, both to heat your space efficiently and for safety reasons. Not all patio heaters are suitable for all spaces, so we’ve put together a reference guide for the best patio heaters for every home. 

Choosing a patio heater by area size

No matter which type of heater you choose, your purchase of the patio heater should take into consideration the size of the area you need heated. Look for the BTUs (British Thermal Units) listed on the patio heater. The larger the BTUs, the wider the radiant heat travels. There are a few ways to calculate how many BTUs you need in your space; however, we can save you the time and math, and tell you the average 20x20 patio needs around 84,000 BTUs, which is equivalent to two large propane heaters. 

Best natural gas patio heaters

These rather large — and fairly permanent — structures are much more expensive in the initial purchase than some other heaters, but by connecting to your home’s gas line, they save money in the long run. There are no propane tanks to refill, which can get expensive over time. And because they are running off the main gas line, they won’t run out of heat. The typical propane heater lasts only about 10 hours at most.

  • Pros: The natural gas-powered patio heaters have an endless supply of heat, as the natural gas line won’t run out. They are also less expensive to operate in the long run, averaging around $.47 per hour to operate.
  • Cons: These patio heaters are expensive at the initial purchase, running around $1500 for an average model. They require professional installation and are not portable. 

Our Pick: Stainless Steel Natural Gas Patio Heater

These stainless-steel beauties emit a lot of heat, look good, and are relatively cost-effective for a permanent natural gas patio heater. Made for the serious outdoor entertainer, the Fire Sense heater connects to your home’s natural gas line and has a heavy-duty mounting plate that keeps the heater from tipping over, even in strong winds. It assembles easily and has an easy-to-use quick-start ignition.

Best propane patio heaters

If you’ve been seated outdoors at a restaurant, you’ve probably enjoyed the radiant heat from a portable propane heater. They’re affordable for home use, and are great for larger, outdoor spaces. These patio heaters are run off of a replaceable propane tank, and while they’re heavy, they usually come on wheels and are fairly easy to move around a patio or deck. They are easy to assemble and use right away, as long as your propane tank is full.

  • Pros: Propane tank patio heaters are very easy to assemble and they are relatively inexpensive at the initial purchase. While not particularly lightweight, most come with wheels and are relatively easy to move around the patio or outdoor living space.
  • Cons: A 20-gallon propane tank will run anywhere from 9-15 hours before running out of gas. The patio heaters are large and a little bulky, and not suitable for use in enclosed spaces. In addition, they cost around $1.60 per hour to operate.

Best electric patio heater

If you have a small space that’s mostly enclosed, you’ll want to look at an electric patio heater. Since propane or gas heaters should not be operated inside or on screened-in spaces, because the gas fumes can accumulate, any sunrooms, enclosed patios, or screened-in porches should use electric patio heaters. Most electric heaters give off infrared heat, are energy efficient, and safe to use. However, they can often require higher voltage than the standard electrical outlet and may require an electrician to install. There are also halogen heaters that use halogen bulbs that are heated by an electric current. These provide a lot of heat, but the heater itself remains cool to the touch, making it safe for children and pets.

  • Pros: These electric heaters can hang from the ceiling or be tabletop and come in a wide variety of sizes. They run on electricity, so if you don’t have gas they are a nice option. They are also safe to operate in an enclosed space.
  • Cons: These electric patio heaters may need professional installation, as some require outlets with 240
