How to Choose the Best Natural Gas Outdoor Heaters

🔥 Introduction

When the evenings grow cooler, a natural gas outdoor heater can turn your patio into a warm, inviting space for family dinners, weekend barbecues, or simply relaxing under the stars. But with so many options out there, finding the right heater can be a little overwhelming. This guide will walk you through everything you need to know—whether you’re looking for the best natural gas patio heater for a large outdoor area or a wall-mounted unit for your alfresco space. We’ll help you choose based on your lifestyle, space, safety, and energy efficiency needs.

✅ Why Choose a Natural Gas Outdoor Heater?

Natural gas outdoor heaters are popular for a good reason. They tend to have lower running costs than electric or propane options, meaning you’ll save money in the long run—especially if you use your outdoor space frequently. One of their best perks is the continuous gas supply, so there’s no need to replace tanks or worry about running out mid-party. Plus, natural gas heaters usually provide a higher heat output, delivering better warmth coverage for larger spaces. They’re also considered more eco-friendly, emitting fewer pollutants than some propane outdoor heaters or wood-burning options. All of these benefits make them a smart and sustainable choice for home heating.

📐 Assessing Your Outdoor Space

Before choosing a heater, it’s important to evaluate your space. The size of the area will determine how powerful your heater needs to be. For instance, a small balcony might only need 20,000 BTU, while a spacious deck could require up to 50,000 BTU. Also, consider how wind exposure might affect heat dispersion—open, breezy areas will lose warmth faster, so placing your heater near walls or using windbreaks can help. If your patio is covered, it will retain heat better, but make sure there’s adequate ventilation for safety. Since most natural gas heaters are fixed installations, you’ll need to plan ahead whether it’s wall-mounted or ceiling-mounted, as portability isn’t an option like it is with propane models.

🔧 Key Technical Features to Consider

🧰 Installation Requirements

Installing a natural gas outdoor heater isn’t a DIY task. These units need to be professionally installed and connected to your home’s gas line, which must be done by a licensed gas fitter or plumber. Depending on your location (especially in Australia), there may be permit requirements you’ll need to meet. It’s also important to ensure the heater’s gas pressure matches your home’s supply—most models require around 7–10 inches of water column pressure. Be sure to review clearance guidelines as well; ceiling or wall-mounted units require minimum distances from flammable surfaces to prevent fire hazards. Planning the installation carefully will not only keep things safe but also ensure your heater works efficiently from day one.

🛡️ Safety Features and Certifications

Safety should always be top of mind when choosing an outdoor heater. Look for models with a Flame Failure Device (FFD), which automatically cuts off the gas if the flame goes out—an essential feature for preventing gas leaks. If you’re using a freestanding model, tilt switches are a great safety bonus, as they shut the unit off if it gets knocked over. Always choose heaters that have safety certifications, like CSA or AGA, to ensure they meet Australian or North American safety standards. Remember, these heaters are designed for outdoor use only, so they’re not suitable for enclosed patios, garages, or indoor spaces, even if they’re ventilated.

💡 Energy Efficiency and Long-Term Costs

Natural gas heaters are well-known for their energy efficiency. While the initial setup may cost more, they offer lower operational costs over time, especially when compared to electric heaters. To understand your future expenses, calculate the BTU/hr of the model and convert it into cubic meters of gas to estimate fuel usage. If energy savings are a priority, look for models with a thermal efficiency rating of 80% or higher. These models will convert most of the gas into usable heat instead of wasting it. All in all, if you’re using your heater regularly, a natural gas model can provide significant savings.

🧼 Maintenance and Lifespan

To keep your heater in top shape, you’ll need to perform some regular maintenance. For starters, clean the burner ports occasionally to prevent blockages from dust or insects. Inspect gas lines annually for signs of corrosion or leaks, especially before each winter season. If your unit uses batteries or an electric igniter, expect to replace those parts every few years. Protect your investment by covering your heater when it’s not in use or during long periods of rain. With proper care, a high-quality natural gas heater can last 10 years or more, making it a great long-term addition to your outdoor space.
