🔥 Introduction
Electric outdoor heaters are becoming a staple in many homes, especially for those who enjoy spending time outside during cooler months. They’re clean, convenient, and surprisingly efficient. Whether you’re entertaining on the patio or just enjoying a quiet evening under the stars, the right heater can make all the difference. This guide will help you understand what to look for in an electric outdoor heater—from types and wattage to safety features and mounting options.
Electric Outdoor Heater Types: Infrared vs Fan-Forced
When choosing an electric outdoor heater, the first thing to consider is the type. Infrared (or radiant) heaters are often preferred for outdoor use because they heat people and objects directly rather than warming the air. This means they provide almost instant warmth and aren’t affected by wind. On the other hand, fan-forced (or convection) heaters blow warm air to heat up a space more broadly, which is great for enclosed or semi-enclosed patios.
However, they can take longer to feel effective and may not perform as well in open, breezy areas. Radiant heaters also convert nearly 100% of energy into usable heat, making them extremely efficient. If you’re after fast, targeted warmth on a deck or balcony, an infrared model is likely your best bet.
Heat Output & Coverage
Heat output is usually measured in watts or BTUs, and it’s important to match this to the size of your outdoor area. A good rule of thumb is to allow around 20 BTUs per square foot. For example, if your patio is 200 square feet, you’ll need at least a 4,000 BTU heater—which is about 1,200 watts. Most electric heaters for outdoor use range from 1,200 to 1,500 watts and can comfortably heat a space of around 6 to 10 feet in radius. If you have a larger area, consider using multiple heaters or choosing a model that oscillates to spread heat more evenly. It’s all about matching the heat coverage to your specific needs.
Energy Efficiency & Operating Costs
One of the biggest advantages of electric heaters is their efficiency. Unlike gas heaters, electric models can convert nearly 98 to 100 percent of electricity into heat. This means less waste and more savings in the long run. Operating costs will depend on your local electricity rates, but on average, a 1,500-watt heater running for four hours might cost around $2 to $3 AUD. When you factor in the convenience—no propane tanks or fuel refills—it’s easy to see why electric heaters are a smart, low-maintenance option.
Safety Features & Certifications
Safety should be a top priority when choosing an outdoor heater. Look for models with built-in tip-over protection and overheat shut-off mechanisms, both of which automatically power off the unit to prevent accidents. It’s also essential to choose a heater with a suitable IP (Ingress Protection) rating—IPX4 or higher—for resistance against splashes and rain. Reputable certifications like UL (US), CE (EU), or RCM (Australia) give you added peace of mind. Always use outdoor-rated power cords and place heaters on stable, flat surfaces to avoid mishaps.
Mounting Style & Portability
Think about how and where you’ll use your heater. Freestanding models are perfect if you need to move the heater around your yard or deck. They’re versatile and easy to set up. If space is limited, wall- or ceiling-mounted heaters are excellent space-savers and keep cords out of the way. Pedestal or tabletop options integrate nicely into outdoor dining setups, offering both functionality and style. Choose a mounting style that fits your layout and lifestyle.
Features & Added Convenience
Today’s electric heaters come with a range of smart features that make them easier and more enjoyable to use. Remote controls, built-in thermostats, oscillation modes, timers, and multiple heat settings allow you to tailor the warmth to your comfort level. Some models even offer child lock functions and ultra-quiet operation, perfect for family settings or relaxed evenings outdoors. These extra features aren’t just luxuries—they can significantly improve your overall heating experience.
Durability & Weather Resistance
Because outdoor heaters face the elements, it’s vital to choose a model made from weather-resistant materials like stainless steel or powder-coated aluminum. Look for models with an IP rating of at least IPX4 to ensure they can withstand splashes and light rain. To extend your heater’s life, cover it when not in use or store it indoors during extreme weather. A bit of care goes a long way in preserving your investment.
Cost Considerations & Maintenance
Prices for electric outdoor heaters can range from $60 to over $900 AUD, depending on features, wattage, and build quality. Budget models around $150–200 can still offer reliable performance, while higher-end units include features like smart thermostats and high IP ratings. Maintenance is generally minimal: wipe down the unit regularly, check cords for wear, and store it in a dry place when not in use. Electric heaters are a cost-effective and low-hassle solution for outdoor warmth.
Frequently Asked Questions
Infrared heaters are ideal for open patios because they emit radiant heat that warms people and objects directly, rather than heating the air. This makes them more effective in breezy or exposed environments.
A simple rule is to allocate 20 BTUs or ~6 watts per square foot. For a 200 sq ft patio, you’ll need at least a 1,200W–1,500W heater. If your space is larger, consider multiple units or a high-output model.
Yes. Electric outdoor heaters, especially infrared models, convert up to 100% of electricity into heat, making them more efficient than gas alternatives and often cheaper to run long-term.
Only if the heater is IP-rated (Ingress Protection) for outdoor use. Look for IPX4 or higher, meaning it can handle splashes or light rain. Always read the manufacturer’s instructions for weather guidelines.
Prioritize models with:
-
Tip-over switch (shuts off if the unit falls),
-
Overheat protection,
-
Cool-touch housing, and
-
UL/CE/RCM certifications for electrical safety.
Wall- or ceiling-mounted heaters are great for saving floor space and are ideal for covered patios. Freestanding heaters offer more flexibility and are better for movable setups or temporary use.
It depends on your local electricity rate. A 1,500W heater running for 4 hours uses about 6 kWh, which could cost $2–$3 AUD. Compared to propane, it’s more consistent and requires less maintenance.
No. Indoor heaters are not weatherproof and lack the proper IP rating. Only use heaters specifically designed for outdoor use to avoid fire or electrical hazards.
Most quality models last 5–10 years with proper care. Keep the heater clean, store it in dry conditions, and protect it from extreme weather to extend its life.
Many modern heaters include remote controls, smart thermostats, or timers for added convenience. Look for these features if you prefer hands-off control or want to adjust settings from a distance.
Portable units are easy to install—just plug and go. For wall- or ceiling-mounted heaters, follow the installation manual carefully, and consider hiring an electrician if hardwiring is required.
Electric models are safer than fuel-based heaters, but still pose a risk if misused. Always follow clearance guidelines, avoid using near flammable materials, and never operate unattended.
Look for heaters made from stainless steel or powder-coated aluminum. These resist rust and corrosion better than plastic or low-grade metals, especially in coastal or rainy climates.
If your model is IP-rated for outdoor use, it can typically be left outside. Still, it’s best practice to cover it or store it in a dry area when not in use, especially during storms or long periods of disuse.
-
Quartz heaters heat up quickly and offer intense radiant heat—best for short sessions.
-
Carbon heaters are more energy-efficient and emit a softer, longer-lasting heat—ideal for prolonged use.
Buying Checklist
To wrap it all up, choosing the best electric outdoor heater involves looking at the type (infrared or fan), the wattage and coverage area, safety features, mounting options, and bonus features like remote controls or oscillation. Don’t forget to factor in durability, energy costs, and warranties. With a little research and planning, you’ll find a heater that keeps your outdoor space warm, safe, and inviting all year long.
