The Complete Guide to Patio Heaters

As summer gives way to fall, outdoor spaces like patios and terraces can lose their appeal due to the dropping temperatures. This is where patio heaters come in, transforming your outdoor area into a cozy, inviting space even during the cold season. Whether you have an evening gathering or just want to enjoy a quiet moment outside, patio heaters ensure that your outdoor experience remains comfortable even in cool weather. 

In this guide, we discuss everything you need to know about patio heaters, including the different types available, and how to choose the best one for your patio or terrace.

What Are Patio Heaters?

Patio heaters are devices designed to radiate heat in outdoor spaces. They come in various forms and sizes, catering to different types of outdoor environments such as patios, decks, and backyards. 

These heaters use energy sources such as propane, natural gas, or electricity to produce heat, which is then distributed over a specific area. Patio heaters help extend the usability of outdoor spaces year-round, making them essential for homeowners, cafes, restaurants, and other venues with outdoor seating.

Compared to indoor heaters like space heaters, patio heaters are designed to be more robust to withstand the outdoor elements. 

Why Use a Patio Heater?

🗸 Extended use: With a patio heater, you can use your outdoor space during cooler months, ensuring year-round enjoyment.

🗸 Comfort and ambiance: Patio heaters not only provide warmth but also create a cozy ambiance. Whether for family gatherings, outdoor dining, or just relaxation, they make outdoor areas more inviting.

🗸 Convenience: Since indoor heaters are not designed to be left outside all the time, they need to be brought indoors after use. A dedicated outdoor heater saves you from the hassle of setting up and packing up the heater each time.

🗸 Energy efficiency: Patio heaters are designed to warm outdoor spaces efficiently without the need for centralized heating. This allows for localized, cost-effective heating when needed.

The Different Types of Patio Heaters 

Patio heaters are classified by their fuel type and heating method. Each type has its own pros, which should be considered based on your needs, patio space, and preferences.

1. Propane Patio Heaters

Propane patio heaters are one of the most popular options for residential and commercial use. These use a propane tank to generate heat. They are also available in portable models, allowing for flexibility in placement.

Heating Method: Propane heaters produce heat through combustion. A propane flame heats the surrounding air, which then radiates outward to warm the patio area.

Pros:

• Easy to move and reposition due to their portability.
• Does not require permanent installation.
• Provides immediate heat.
• Available in different sizes, from tabletop models to large standing units.

Cons:

• Propane tanks need to be replaced regularly, adding to operational costs.
• Requires proper ventilation due to the combustion process.
• Not as environmentally friendly as other heater options.

It runs on a 20 lb propane tank (not included). The propane tank is secured with a strap for safe portability and concealed in the base of the unit behind the rear cover.

2. Natural Gas Patio Heaters

Natural gas patio heaters are often chosen for their continuous fuel supply, eliminating the need to replace tanks like propane models. These heaters are typically fixed in place and connected to a natural gas line.

Heating Method: Like propane heaters, natural gas heaters use combustion to generate heat. The natural gas burns to produce heat that is radiated into the surrounding area.

Pros:

• Lower operating cost compared to propane.
• No need to change or replace fuel, since it’s connected to a natural gas line.
• Consistent, uninterrupted heat supply.

Cons:

• Requires professional installation to connect to the gas line.
• Lacks portability; once installed, they are fixed in place.
• Higher upfront costs due to installation requirements.

3. Electric Patio Heaters

Electric patio heaters are a popular choice for homeowners looking for an eco-friendly and convenient heating option. They can be used in various outdoor settings.

Heating Method: Electric patio heaters use infrared technology to generate heat. Rather than warming the air, they directly heat objects (and people) within their range.

Pros:

• Low cost
• No emissions, making them environmentally friendly.
• Available in many sizes and designs, including wall-mounted and freestanding models.
• Safe for use in enclosed areas or spaces with limited ventilation.

Cons:

• Requires an outdoor power outlet or extension cord.
• Can have higher energy costs compared to natural gas.
• Generally less powerful than propane or natural gas heaters, limiting them to smaller patios.

4. Wood-Burning Patio Heaters (Fire Pits and Chimineas)

Wood-burning patio heaters include fire pits and chimineas. These not only provide heat but also create a cozy, rustic ambiance. They are often used in open outdoor areas where ventilation is not a concern.

Heating Method: The combustion of wood in an open flame generates heat that radiates outward. The heat intensity depends on the size of the fire and the type of wood used.

Pros:

• Aesthetic appeal; creates a warm and inviting atmosphere.
• No fuel costs if you have access to firewood.
• Can double as a cooking flame such as for roasting marshmallows or grilling.

Cons:

• Requires constant attention to keep the fire going.
• Produces smoke, which may not be ideal for all environments.
• Not suitable for small or enclosed patios due to fire and smoke concerns.

How to Choose the Right Patio Heater

Choosing the right patio heater depends on several factors, including the size of your outdoor space, your budget, and your heating preferences. 

1. Patio Size and Layout

Consider the size of your patio and how much heat coverage you need. Larger patios or commercial spaces will require more powerful heaters, such as propane or natural gas units, while smaller, more enclosed spaces may benefit from electric heaters. In many cases, more than one heater will be required. 

Different heaters provide different ranges of heat. Check the heater’s BTU (British Thermal Unit) rating or wattage to estimate how much area it can cover. 

2. Placement

Patio heaters can be tabletop, wall-mounted, ceiling-mounted, or freestanding. Consider where you want to place them on the patio.

2. Portability

If you want to move your heater around or only use it in specific areas, opt for a propane or electric model that is lightweight and portable. Natural gas heaters tend to be fixed and are only for permanent installation in specific areas.

4. Installation 

Consider whether you want a heater that requires professional installation, such as a natural gas heater, or one that is ready to use out of the box, like an plug in electric or propane model. 

5. Maintenance 

Propane and wood heaters may require regular fuel replacement, while electric heaters have lower upkeep requirements. Wood-burning heaters produce a lot of soot and byproducts and require more cleaning.

5. Safety Features

Look for patio heaters with safety features like automatic shut-off if the heater tips over or overheats. For wood-burning models, make sure they are used in safe, open areas to avoid fire hazards.

Key Features to Look For

🗹 BTU / wattage rating: This determines the heat output and coverage.

🗹 Fuel efficiency: Choose a heater that provides optimal heat without excessive fuel consumption. AFUE (annual fuel utilization efficiency) measures how much fuel it uses to heat for a specific period of time. Higher AFUE ratings mean higher fuel efficiency.

🗹 Aesthetics: Consider whether the heater complements your outdoor decor.

🗹 Weather resistance: Ensure the heater is durable and designed to withstand outdoor conditions like rain and wind. This is particularly important for regions that experience extreme conditions.

🗹 Safety mechanisms: Tip-over protection, auto-shutoff, and child-proof features are crucial for family safety.

Conclusion

If you like to spend time on your patio or deck, patio heaters are an excellent investment for extending their usability during the off-season. By considering factors like the size of your space, installation and fuel type, you can stay warm and comfortable on your deck chair year round.
