Best Outdoor Heater


A good patio heater has the power to expand a deck or patio from strictly warm weather use to a year-round living space for relaxing entertaining. Outdoor heaters come in 1,500-watt electric units that can produce up to 5,100 BTUs, gas heaters that can pump out a scorching 50,000 BTUs of heat, and wood-burning heaters that add the warmth and appeal of a crackling fire.

These powerful heaters are available in a variety of shapes in sizes, including 7-foot-tall tower heaters that provide warmth within a 360-degree heating zone, wall heaters that provide heat while remaining up and out of the way, and inviting table heaters that resemble the classic fire pit.

In this guide are the different types of patio heaters and the factors to consider when shopping for one of these units in addition to some of the best patio heater models on the market.

Types of Outdoor Heaters 

Outdoor patio heaters use three different possible fuel sources: gas/propane, electric, and wood. Electric heaters are convenient and versatile, while gas and propane heaters offer superior heating power. Wood offers the allure of an open fire. Ahead, discover the advantages and disadvantages of each outdoor heater type.


Electric outdoor heaters work much like their indoor brethren. They plug into a standard 120-volt outlet, offer the same max power of 1,500 watts (the equivalent of 5,100 BTUs), and produce infrared heat, which warms skin and clothing directly as opposed to the surrounding air.

One of the biggest advantages of an outdoor electric heater is ease of use. Simply flip a switch to activate the heating element. Electric outdoor heaters also come in a variety of forms. They can function as stand-alone heaters or as wall-mount heaters. They can even be moved indoors for heating a garage or living space. That said, they don’t provide the same amount of heat as a gas heater, so users may need to don a good outdoor blanket for supplemental warmth.

Given that they use electricity for power, there are safety factors to take into account with an outdoor electric heater. An outdoor electric heater should have an IP Code (International Protection Code) rating of 55 or higher, which means the heater can withstand dust and low-pressure streams of water.


Gas and propane outdoor heaters generate more heat than electric models, with the ability to pump out a blazing 50,000 BTUs. While a gas heater will heat more space, it is more susceptible to wind and heat dispersion, because a gas heater warms the air around it while an electric heater warms people and objects directly. This type of heater also isn’t as easy to fuel. It requires a propane tank, which the user must periodically replace with a full one, and this can be inconvenient.

Gas and propane outdoor heaters feature all-metal construction that’s weather resistant. This type of heater also does not present the same hazards as outdoor electric heaters. Most gas outdoor heaters have safety devices that automatically shut off the unit if it tips over.


Wood backyard patio heaters are made of either metal or stone. Shoppers might find box-shaped or bowl-shaped open fire pits that provide heat in all directions around the pit. Chimineas are also available; they feature a firebox and a small chimney that provides heat from all slides or one side, depending on the design.

Chimineas and fire pits both typically sit a foot or more off the ground to prevent the flames from reaching the patio below. The amount of heat a wood patio heater can produce is based on size.

A 36-inch-diameter fire pit can hold more fuel, and hence produce a larger fire than a 20-inch-diameter model. Wood fire pits require more work than a gas or electric fire pit, as the user must build and maintain the flame and periodically clean ash out of the unit.

What to Consider When Choosing the Best Outdoor Heater

Heat output, style, and coverage area are crucial factors to consider when selecting the right heater for an outdoor living space. Read on to learn about these and other important considerations one should make when shopping for the right patio heater for an outdoor living space.

Area Size

The area of the patio largely determines the required size of the heater. A freestanding patio heater that produces 40,000 BTUs per hour can heat a 20-foot-diameter space, while a tabletop heater pumping out 30,000 BTUs can heat a radius of 5 to 8 feet.

Keep in mind that the heater’s ability to heat an area to a comfortable temperature depends on the air temperature. A gas outdoor patio heater will warm the air around it between 3 and 7 degrees above the air temperature with the area closest to the heater receiving the most warmth. Electric heaters will only heat people and objects in close proximity to the heater.


Patio heaters come in a variety of shapes and sizes. Consider which style would best suit your outdoor space:

  • Freestanding heaters often have a cylindrical base with a pole that extends upward to a large heating element and heat shield. This style of heater is ideal for patios as it provides a 360-degree heating zone. They come in different colors and finishes to suit different styles.
  • Wall-mounted heaters attach to the wall and are typically elevated about 6 feet off the ground. They are long and narrow and radiate heat using an electric element.
  • Tabletop heaters consist of a small heater with an exposed gas flame. This type of heater doesn’t produce as much heat as other models but does add an aesthetic element that other styles lack.
  • Hanging heaters are usually installed from the ceiling of a covered porch. They look similar to a light fixture; however, instead of emitting light, they emit infrared heat.
  • Fire pits are a popular outdoor heating option and add a stylish touch to the deck or patio. These elements are available as electric and gas models, and many are multifunctional; for instance, certain fire pits can be used as grills and some have a built-in tabletop.

Power Source

Outdoor heaters use different energy sources, which affects their functionality:

  • Propane heaters use propane gas that comes in a 20-gallon steel container. These containers provide about 10 hours of heat before requiring a refill.
  • Natural gas heaters connect directly to a home’s gas supply, providing a limitless amount of fuel and eliminating the need for inconvenient runs to the gas station or supermarket for a replacement propane tank.
  • Electric heaters plug into a standard 120-volt outlet for power, while wood requires a steady supply of firewood for fuel.

Heat Output

The amount of heat put out by a patio heater is measured in BTUs (British thermal units) for gas heaters and watts for electric heaters. Naturally, the heat output of a wood-burning patio heater is determined by the size of the fire. Electric heaters are limited to 1,500 watts, which is just under the 1,800 maximum watt output of a standard 120-volt outlet.

A 1,500-watt heater puts out roughly 5,100 BTUs of heat (3.4 BTUs of heat per watt). Propane and natural gas heaters, in comparison, can generate up to 46,000 BTUs of heat, making them ideal for covering large spaces.


Patio heaters range in size and, hence, portability, though most have fairly limited portability. Particularly wall-mounted, hanging, and fire pit heaters, which are stationary units. That said, there are some smaller, lighter fire pits available.

Large freestanding patio heaters have small wheels on the base that allow the user to move them to different locations on the patio. These models tend to be large and heavy, making them impractical for transport to another location.

Most tabletop heaters are less than 3 feet high, weigh less than 20 pounds, and use 1-pound propane canisters. For these reasons, tabletop devices are ideal for camping trips and other excursions.


Given that outdoor heating units put out a tremendous amount of heat, they are fire and burn hazards. Most outdoor heaters have safety shutoffs to prevent fires. Gas and electric heaters have tip-over safeties that automatically shut off the unit in the event it falls over.

Models with heating elements that are within reach of children and pets feature protective grates that prevent accidental burns. Many electric models have programmable shut-off timers to prevent the heater from being left on.

When using a space heater, it’s important to pay attention to its safety guidelines. Be sure to adhere to the clearance requirements, which dictate how far the heater should be from structures and patio furniture. Never use an outdoor patio heater indoors unless it is rated for indoor use.

Cost and Maintenance 

When it comes to the cost of running an outdoor heater, propane is generally the most expensive, followed by electric and natural gas. The cost of running a wood-burning patio heater depends on the cost of firewood. If you live in a wooded area, this would be a cost-effective power source.

Electric patio heaters require the least amount of maintenance, as they do not have ignition devices that can wear out if not periodically cleaned, nor do they produce ash. That said, once an electric patio heater malfunctions, it is not easy to repair, typically requiring replacement.

In comparison, parts on a gas patio heater, such as the valve and ignition, are fairly easy to replace. Wood fire patio heaters will generally last the longest since they have no mechanical parts.

FAQs About Outdoor Heaters

If you’re still wondering about what size outdoor heater is right for your patio, then read on for answers to some of the most commonly asked questions about outdoor heater performance.

Q. Do outdoor heaters work in the winter?

Outdoor heaters work well in winter. Although propane can be affected by extreme cold with temperatures well below zero, the fuel will work just fine in other conditions.

Q. Can you use a patio heater on a covered porch?

A patio heater can safely be used under a covered porch as long as it meets the heater’s requirements for clearance. If using a tower heater, make sure there is adequate space between the top of the heater and the ceiling of the covered roof.

Q. How big an area does a patio heater heat?

The average outdoor heater can heat about 100 square feet of space.

Q. How many BTUs do I need for my patio heater?

Begin by determining how big a space you are warming. Calculate the area of the patio by calculating the length times the width. Then multiply the square footage by 20 BTUs to determine the output you need to adequately warm the space. For example, a 300-square-foot patio would need a heater with 6,000 BTUs of output. Keep in mind that multiple small patio heaters spaced out will provide more even heat than one large one.

Q. How many watts does my patio heater need?

An electric patio heater isn’t as powerful as a gas one, so it’s essential that an outdoor electric heater have 1,500 watts of output, which is the most an electric heater can produce.

Q. Do patio heaters use a lot of electricity?

Patio heaters do use a lot of electricity, in the sense that they operate continuously at 1,500 watts. However, as is discussed above, the cost of using an electric heater is still significantly less than the cost of using a propane heater.
