- Extend Usable Space: Turn your unused patio into a functional living area for more of the year.
- Enhance Comfort: Enjoy outdoor dining, entertaining, or relaxing even when temperatures drop.
- Increase Home Value: A well-utilized and comfortable outdoor space can be a significant selling point.
- Create Ambiance: Many patio heaters offer a warm, inviting glow that adds to the atmosphere.
Types of Outdoor Heaters for Enclosed Patios
When looking for outdoor heaters for an enclosed patio, safety and proper ventilation are paramount. The type of heater you choose will depend on your patio setup, fuel availability, and heating needs. Here are the main categories:
1. Electric Patio Heaters
Electric heaters are a popular choice for their ease of use and minimal setup. They plug into a standard electrical outlet and emit infrared heat, which warms objects and people directly rather than just the air. This makes them quite efficient for enclosed spaces.
- How they work: Electric elements heat up and radiate infrared waves.
- Pros:
- Easy to install and operate – just plug them in!
- No fuel storage or refilling required.
- Generally produce no fumes, making them suitable for enclosed spaces with good airflow.
- Available in various styles like wall-mounted, ceiling-mounted, and freestanding.
- Often have adjustable heat settings.
- Cons:
- Require an electrical outlet nearby.
- Heating capacity can be limited by the strength of the electrical circuit.
- Can be less effective in very large or heavily drafty spaces compared to gas heaters.
- Ongoing electricity costs can add up.
- Ideal for: Smaller to medium-sized enclosed patios, areas with readily available power, and those prioritizing convenience and minimal emissions.
2. Propane Patio Heaters
Propane heaters are very common for outdoor use. They run on propane tanks, offering flexibility in placement since they don’t require a power source. However, proper ventilation is crucial due to the combustion process.
- How they work: Propane gas is burned to produce heat, usually directed upwards or outwards.
- Pros:
- Highly portable and can be placed almost anywhere on the patio.
- Produce significant heat, suitable for larger areas.
- No electricity needed, making them independent of power outages.
- Quick to heat up a space.
- Cons:
- Require propane tank refills or exchanges.
- Produce carbon monoxide and other combustion byproducts, so adequate ventilation is absolutely essential for enclosed patios. Inadequate ventilation poses a serious safety risk.
- Tanks can be heavy and some find storing them inconvenient.
- Noise from the burner can be a factor.
- Safety Note: For enclosed patios, propane heaters MUST be used with extreme caution and ensure proper ventilation. Many manufacturers recommend against using them in fully enclosed spaces without professional consultation or specific models designed for such use. Always follow manufacturer guidelines for safe operation and ventilation. A common recommendation is to ensure at least one side of the enclosure is at least 50% open.
3. Natural Gas Patio Heaters
If your home is connected to a natural gas line, a natural gas heater is an excellent, convenient option. They are permanently installed and don’t require refilling, but this means they are less portable and require professional installation.
- How they work: Similar to propane heaters, they burn natural gas to generate heat, but are connected directly to your home’s gas supply.
- Pros:
- Unlimited fuel supply as long as your gas line is active.
- No need to store or exchange tanks.
- Can provide substantial heat.
- Often considered more eco-friendly than propane in terms of direct emissions per BTU, though they still produce combustion byproducts.
- Cons:
- Require professional installation and a gas line connection to the patio.
- Less portable than propane or electric heaters.
- Produce carbon monoxide and other combustion byproducts, requiring careful ventilation planning for enclosed patios.
- Installation costs can be significant.
- Safety Note: Similar to propane heaters, natural gas heaters produce carbon monoxide. It is crucial to ensure adequate ventilation in an enclosed patio. Consult with the installer and manufacturer about safe operating parameters for your specific patio enclosure.
4. Infrared Heaters (Radiant)
Both electric and gas heaters can be radiant. Radiant heaters work by emitting infrared radiation that directly heats objects and people in their path, much like the sun. This is often preferred for enclosed spaces because they don’t rely on heating the air, which can escape through gaps.
- How they work: Emit infrared waves that are absorbed by surfaces.
- Pros:
- Efficient in enclosed spaces as they don’t lose heat to the air.
- Instant heat, no warm-up time needed.
- Can be electric or gas-powered.
- Quieter operation than some convection heaters.
- Cons:
- Heat is directional, so you need to be in the heater’s “beam.”
- Gas-powered radiant heaters still require ventilation and produce byproducts.
- Ideal for: Providing targeted warmth in specific seating areas within an enclosed patio.
Key Factors When Choosing an Outdoor Heater for Enclosed Patios
Selecting the right heater isn’t just about picking one that looks nice. Several practical factors come into play, especially when you’re dealing with an enclosed space. Let’s break them down:
1. Heat Output (BTUs and Wattage)
Heat output is typically measured in British Thermal Units (BTUs) for gas heaters and watts for electric heaters. The higher the number, the more heat the unit produces. For an enclosed patio, you don’t necessarily need the most powerful heater on the market, as heat can be trapped. However, you do need enough to overcome the ambient temperature and make the space comfortable.
- Electric: Look for units between 1500-2500 watts. These are generally safe to run on standard home circuits, but always check the specifications.
- Propane/Natural Gas: These can range from 10,000 BTUs to over 40,000 BTUs. For a moderately sized enclosed patio (e.g., 10×12 feet), a heater in the 20,000-30,000 BTU range might be sufficient, especially if it’s radiant. Always err slightly on the side of caution and consider one with adjustable settings.
Tip: A good rule of thumb for gas heaters is to aim for 20-30 BTUs per square foot for moderately cold weather. For enclosed spaces, you might get away with slightly less due to heat retention.
2. Fuel Source and Availability
Your choice of fuel source heavily influences the convenience and cost of operation. Consider what’s readily available and practical for your home:
- Electricity: Simple, as long as you have an outdoor-rated electrical outlet easily accessible.
- Propane: Requires purchasing or exchanging propane tanks. This offers placement flexibility but adds a recurring task and cost.
- Natural Gas: Requires a permanent gas line connection, meaning professional installation and therefore higher upfront costs, but no ongoing fuel hassle beyond your utility bill.
For enclosed patios, the clean-burning nature of electric heaters can be a significant advantage if sufficient heat can be achieved. If opting for gas (propane or natural gas), ventilation is non-negotiable.
3. Safety Features and Certifications
Safety is paramount, especially with heaters producing combustion byproducts in an enclosed area. Look for heaters with:
- Tip-over Protection: Automatically shuts off the heater if it’s knocked over.
- Oxygen Depletion Sensor (ODS): Essential for propane and natural gas heaters. It shuts off the gas supply if oxygen levels drop below a safe threshold, preventing carbon monoxide buildup.
- Flame Failure Device: Shuts off the gas if the pilot light or burner goes out.
- Certifications: Look for certifications from recognized safety organizations like CSA (Canadian Standards Association) or UL (Underwriters Laboratories). They ensure the product has met rigorous safety standards.
For enclosed patios, always double-check the manufacturer’s recommendations regarding safe usage and required ventilation. Some units are not suitable for fully enclosed areas at all. You can find guidance on safe patio heating practices from organizations like the National Fire Protection Association (NFPA), though their primary focus is grilling, the principles of safe combustion and ventilation apply.
4. Patio Size and Layout
The dimensions and shape of your enclosed patio will influence how heat is distributed. A small, compact patio might be efficiently heated by a single electric or smaller gas unit. A larger, more spread-out patio might require a more powerful heater or even multiple units.
- Small Patio (<100 sq ft): A 1500-watt electric heater or a 10,000-20,000 BTU gas heater can be effective.
- Medium Patio (100-200 sq ft): Consider a 2000-2500 watt electric heater or a 20,000-30,000 BTU gas heater.
- Large Patio (>200 sq ft): You may need higher wattage electric heaters (if your circuit can handle it) or more powerful gas heaters (30,000+ BTUs), potentially with multiple units.
Think about where people will be sitting. Radiant heaters are great for directing warmth to specific zones.
5. Ventilation Requirements (Crucial for Enclosed Patios!)
This is arguably the MOST important factor for enclosed patios. Heaters that burn fuel (propane and natural gas) produce carbon monoxide (CO), an odorless, colorless, and deadly gas. In an enclosed space, CO can build up to dangerous levels quickly. Electric heaters do not produce combustion byproducts, making them inherently safer for enclosed patios from an air quality perspective.
General Ventilation Guidelines for Gas Heaters in Enclosed Patios:
- Manufacturer’s Instructions: Always adhere strictly to the manufacturer’s safety and ventilation guidelines.
- Minimum Opening: Many manufacturers recommend that at least one side of the enclosure be at least 50% open, or that there be a minimum of X square feet of opening for every Y BTUs of heat output.
- Professional Advice: If your patio is fully enclosed with minimal openings, it’s wise to consult with a qualified HVAC professional or patio builder to ensure safe installation and operation. They can advise on necessary ventilation solutions.
- CO Detectors: It is highly recommended to install battery-operated carbon monoxide detectors with digital readouts in any enclosed space where combustion appliances are used. Check them regularly and ensure they are functioning correctly.
According to the Centers for Disease Control and Prevention (CDC), CO poisoning can be fatal. Never compromise on ventilation when using fuel-burning heaters.
6. Installation and Maintenance
- Electric: Usually minimal. Typically just requires plugging into an outdoor-rated outlet. Some wall or ceiling-mounted units require basic assembly or mounting.
- Propane: Easy setup – attach the hose to the tank and connect to the heater. Maintenance involves checking the tank, hose, and performing regular cleaning as per the manual.
- Natural Gas: Requires professional installation by a licensed gas fitter. This involves running a gas line hookup to your patio. Maintenance will be similar to other gas appliances in your home.
Always read and follow the owner’s manual for specific maintenance instructions to ensure safety and longevity of your heater.
7. Budget
Patio heaters vary widely in price:
- Electric Heaters: Often range from $100 to $500, with some high-end or designer models costing more.
- Propane Heaters: Tower-style portable heaters can be found for $150-$400. Fire pit style propane heaters can range from $200-$800+.
- Natural Gas Heaters: The heaters themselves might be in the $300-$1000+ range, but installation costs can add significantly ($500-$2000+ depending on complexity).
Don’t forget to factor in the ongoing costs of fuel (electricity or propane) or potential maintenance/repairs.
