While testing, we observed its quiet operation, which makes it ideal for areas where noise is a concern, such as workshops or even indoor emergency use. A common point raised by recent users, and one we acknowledge, is that newer models no longer include the fan that was present in older versions. While this might be a drawback for some, its core heating performance and robust safety features remain undiminished, providing powerful and consistent warmth.

#3 Amazon Basics 46,000 BTU Outdoor Patio Heater with Wheels – Ideal for: High-Output, Value-Oriented Outdoor Patio Heating

For those looking to warm larger outdoor areas without breaking the bank, the Amazon Basics 46,000 BTU Outdoor Patio Heater with Wheels offers an impressive balance of power and affordability. This tower-style propane heater truly delivers on its promise of powerful warmth, creating a comfortable environment within a 9-foot radius, as we experienced firsthand on chilly evenings. Operation is straightforward, featuring a convenient one-touch ignition and an adjustable knob for heat control. Mobility is a key strength; the included wheels make it remarkably easy to reposition, whether we were moving it closer to our dining area or storing it away.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Choosing the perfect propane patio heater can transform your outdoor living space, but with a myriad of options available, it’s easy to feel overwhelmed. Our comprehensive guide is designed to help you navigate the choices, ensuring you select a heater that perfectly matches your needs, space, and budget.

Key Factors to Consider

• BTU Output and Heating Coverage: The British Thermal Unit (BTU) rating directly correlates to the heater’s warming power. For smaller, more intimate spaces, a heater with 10,000-20,000 BTUs might suffice, like our top picks from Mr. Heater. Larger patios or commercial settings may require 40,000 BTUs or more, such as the Amazon Basics or EAST OAK models, to effectively cover a wider radius. Consider the square footage or diameter you need to heat.
• Fuel Type and Portability: While this guide focuses on propane, it’s important to recognize its advantages: self-contained and highly portable. Electric options, like the Dr. Infrared Heater, offer clean, odorless heat but tether you to an outlet. Propane heaters with wheels, like most tower models, offer the best of both worlds for mobility.
• Safety Features: Non-negotiable for any heating appliance. Look for Oxygen Depletion Sensors (ODS) that shut off the unit if oxygen levels become too low, and tip-over protection that automatically cuts the gas supply if the heater is knocked over. Many models, including the Mr. Heater Big Buddy PRO Series, incorporate these critical safeguards.
• Ease of Assembly and Operation: Some heaters, particularly the cabinet-style portable units, come almost fully assembled. Larger tower heaters, while powerful, often require more extensive setup. Consider your DIY comfort level and look for features like one-touch ignition for hassle-free start-up.
• Durability and Material: Outdoor heaters are exposed to the elements, so robust construction is vital. Stainless steel, powder-coated finishes, and weather-resistant components contribute to longevity.
• Design and Aesthetics: Patio heaters are often a focal point. Decide if you prefer a classic tower, a modern pyramid flame (like the Pamapic), or a more discreet cabinet style (like the GASLAND MHA18BN). Some even offer integrated tables for added functionality.

Understanding BTU (British Thermal Unit)

BTU, or British Thermal Unit, is the standard measurement for thermal energy, indicating how much heat a heater can produce. One BTU is the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. In the context of patio heaters, a higher BTU rating means greater heat output and, consequently, the ability to warm a larger area. For instance, a 40,000 BTU heater will project warmth over a significantly wider radius than an 18,000 BTU unit. When selecting a heater, match the BTU output to your outdoor space’s size and how much ambient temperature increase you desire. A good rule of thumb for outdoor spaces is roughly 150-200 BTUs per square foot, though this can vary greatly based on wind exposure, ambient temperature, and whether your patio is covered or open.

Common Mistakes to Avoid

• Underestimating BTU Needs: Purchasing a heater with insufficient BTU for your space is a common pitfall. A small heater won’t effectively warm a large, open patio, leading to disappointment.
• Neglecting Safety Features: Always prioritize heaters with built-in ODS and tip-over protection. These are critical for preventing accidents and ensuring safe operation, especially in areas with children or pets.
• Ignoring Fuel Efficiency: While higher BTUs are desirable, consider the burn time per propane tank. Some heaters offer better fuel efficiency on lower settings, which can save money on refills over time.
• Poor Placement: Placing a heater too close to flammable materials, under low ceilings, or in areas with excessive wind can compromise safety and reduce heating effectiveness. Always adhere to manufacturer clearance recommendations.
• Buying Without Considering Weather Resistance: Not all outdoor heaters are built equal. Ensure the model you choose has appropriate weatherproofing (like an IP rating for electric models) and durable finishes to withstand rain, humidity, and UV exposure.

Frequently Asked Questions

How long does a 20lb propane tank last in a patio heater?

The lifespan of a 20lb propane tank in a patio heater depends entirely on the heater’s BTU output and the setting it’s used on. A typical 40,000-48,000 BTU patio heater running on high might deplete a 20lb tank in about 8-10 hours. Smaller, more efficient heaters like the Mr. Heater Big Buddy PRO Series (18,000 BTU max) can run significantly longer, potentially up to 220 hours on its lowest setting, or around 5-6 hours on its highest setting using two 1lb cylinders, which translates to much longer when hooked to a 20lb tank. Radiant cabinet heaters often offer impressive run times, with some exceeding 30-60 hours on medium to low settings from a 20lb tank. Always check the manufacturer’s specifications for an accurate estimate for your specific model.

What is a good BTU rating for a propane patio heater?

A good BTU rating depends on the size of your outdoor space and the ambient temperature you’re trying to achieve. For smaller, more enclosed patios or decks (under 100 sq ft), a heater with 10,000-20,000 BTUs, like the Mr. Heater portable units, can be sufficient. For average-sized open patios (100-250 sq ft), a 30,000-40,000 BTU heater is often recommended. For larger commercial spaces or very open residential patios, 40,000-55,000+ BTU heaters, such as the Amazon Basics or EAST OAK models, will provide more substantial warmth over a greater area. Consider your local climate and how much wind exposure your area receives, as windy conditions will reduce the perceived heat.

Are propane patio heaters safe on a wooden deck?

Yes, propane patio heaters can be safe on a wooden deck if proper precautions are taken and manufacturer instructions are strictly followed. It is crucial to ensure adequate clearance (typically 2-3 feet) from walls, ceilings, and any combustible materials, including wooden railings or overhead structures. Always place the heater on a stable, level surface to prevent tipping, and ensure it has a reliable tip-over safety switch. Using a protective mat beneath the heater can add an extra layer of safety, especially for older wooden decks. Never leave a propane patio heater unattended, especially when operating on a wooden surface.

Can you convert a propane patio heater to natural gas?

It is generally not recommended to convert a propane patio heater to natural gas unless the manufacturer specifically states that the model is designed for such conversion and provides a certified conversion kit. Propane and natural gas operate at different pressures and require different orifice sizes in the burner assembly. Attempting a conversion without proper knowledge or an approved kit can be extremely dangerous, leading to gas leaks, inefficient burning, or even explosions. Always consult the heater’s manual and, if a conversion is possible, have it performed by a qualified professional.

How do you light a propane patio heater safely?

Lighting a propane patio heater safely typically involves a few key steps: First, ensure the propane tank valve is fully open and that all connections are secure. Next, turn the control knob on the heater to the “Pilot” setting and press it down to allow gas to flow. While holding the knob down, press the ignition button (if available) repeatedly until the pilot flame lights. If there’s no ignition button, use a long-stemmed lighter or match to light the pilot. Once the pilot is lit, continue holding the control knob down for about 10-15 seconds to allow the thermocouple to heat up and keep the pilot lit. Slowly release the knob. If the pilot remains lit, you can then rotate the control knob to your desired heat setting. If the pilot goes out, repeat the process. Always follow the specific lighting instructions in your heater’s manual.

What is a tip-over switch and why is it important?

A tip-over switch is a critical safety feature found in most modern patio heaters. It’s a mechanism that automatically shuts off the gas supply (in propane heaters) or electrical power (in electric heaters) if the unit is accidentally knocked over or tilted beyond a safe angle. This is incredibly important because if a heater tips over while operating, it could ignite nearby flammable materials, leading to a fire. The rapid shut-off provided by a tip-over switch significantly reduces this risk, making the heater much safer for use in busy outdoor areas or homes with children and pets. All the propane heaters we reviewed include this essential safety feature.

How do you store a propane patio heater during the off-season?

Proper storage during the off-season is crucial for extending the life of your propane patio heater. First, disconnect the propane tank and store it upright in a well-ventilated outdoor area, away from direct sunlight, heat sources, and potential ignition sources. The heater itself should be cleaned thoroughly, ensuring no debris is left in the burner or around the heating element. If your heater came with a protective cover (like the Pamapic model), use it. Otherwise, consider purchasing a weather-resistant cover. Store the covered heater in a dry, sheltered location such as a garage, shed, or covered patio, protecting it from harsh weather, moisture, and pests. For models with a weighted base, empty any water or sand before storing to prevent freezing or mold.
