As winter creeps closer and closer with its piles of snow and cold temperatures, outdoor gatherings naturally tend to get more and more challenging. For those who are reluctant to fully relocate indoors during the winter months, outdoor patio heaters can offer an intriguing solution to the problem of freezing temps. Unfortunately, many patio heaters are large and bulky, taking up precious floor space that a small patio can’t sacrifice. Wall-mounted heaters, on the other hand, are designed to save space while bringing comforting heat. Read on to see whether a wall-mounted heater is right for your patio. Plus, discover some highly-rated products in various categories.

What Is a Wall-Mounted Heater?

A wall-mounted heater is attached to or installed on a wall, instead of resting freely on the ground. The main advantage is that it doesn’t take up any floor space, making it ideal for compact patios, or increasing the space for guests and furniture in larger patios. They’re also generally safer to use, since you don’t have to worry about knocking it over and creating a fire hazard.

Types of Wall-Mounted Heaters

Wall-mounted patio heaters can run off electricity, propane or natural gas, using radiant or convection heating.


Electric wall heaters are typically the most popular and affordable. Although their power supply is more expensive to run than propane or natural gas, the units themselves are considerably cheaper. Plus, you can usually install them without professional assistance. Just plug the power cord into an outdoor electrical outlet. They also have a low carbon footprint since they don’t emit any gases, and rarely require upkeep or maintenance.

Propane and Natural Gas

Wall heaters powered by propane or natural gas aren’t as common as electric wall heaters, mostly because these units are generally more expensive and often require a professional to connect the gas supply to the heater. However, gas is a more affordable fuel source than electricity, and gas-powered units are more durable in outdoor conditions.

Aside from the greater expense, other downsides are that they emit greenhouse gases and may require more frequent maintenance.

Convection vs. Radiant Heat

Convection heaters heat up the air in a specific space. Radiant heaters, on the other hand, emit heat waves directly onto objects while bypassing the surrounding air. While there are wall-mounted heaters that use both types of heat, radiant heaters are considerably more energy efficient, since no heat is wasted warming unoccupied air.

Which Heaters Are Cheapest to Run?

Heaters that run on natural gas and propane are the cheapest to run, while electric heaters are the most expensive. That’s because natural gas and, to a lesser extent, propane cost considerably less than electricity in most areas. Regardless of the fuel source, radiant heaters are much more energy-efficient than convection heaters. And, they will be cheaper to operate long term.

Where Can You Put a Wall-Mounted Heater Outdoors?

  • Mounted on walls or ceiling of a patio-covering structure, like a pergola or overhang;
  • Above the door to your patio entrance, to block cold air from entering your home when the door is open.

If installing a convection heater, mount it close to the ground to prevent the hot air from rising and not reaching you.

If installing a radiant heater, ensure it faces directly towards the area you’re trying to heat.

Can You Leave a Wall-Mounted Heater On?

You shouldn’t leave an unattended wall mounted heater on for an extended period of time, especially overnight. Unattended, the excessive heat may ignite any surrounding combustible materials. Fortunately, most modern wall heaters include safety features like overheat shutoffs and automatic shut-off timers to prevent this.

Wall-mounted heaters are also intrinsically safer than floor-mounted units since there’s no tip-over risk. Plus, they’re less likely to be directly in front of combustible objects if the heater is mounted high enough. Even so, it’s recommended to keep at least three feet of open space around your heater to avoid potential fire hazards.
