The Complete Patio Heater Buying Guide for 2025 - Get It Right The First Time
How to Choose the Perfect Patio Heater for Your Outdoor Space
The right patio heater can turn your backyard, balcony, or outdoor dining area into a comfortable spot all year. Whether you’re having friends over, keeping your restaurant’s patio open longer, or enjoying coffee outside on a cool morning, a good heater brings warmth and a touch of luxury. This guide covers the main types of patio heaters, installation options, fuel choices, heat output, design, safety features, and common questions to help you find the best fit for your needs.
Understanding the Two Core Ways Patio Heaters Are Categorized
Patio heaters are classified into two main categories: installation method and fuel type.
Heaters are grouped by how they are installed: overhead models attach to walls, ceilings, or umbrellas, while free-standing heaters include portable, permanent post, and tabletop styles.
By fuel type, patio heaters are either electric or gas, with gas further subdivided into natural gas and liquid propane.
Knowing these two categories will quickly narrow your choices and help you decide which style works best for your home.
Patio Heaters by Installation Style
Overhead Patio Heaters: The Most Seamless, Permanent Heating Solution
Overhead heaters attach to walls, ceilings, pergolas, or umbrellas. They work like a built-in heating system: easy to use, efficient, and out of the way. Most connect directly to a gas line or are hardwired, so they last a long time and need little maintenance.
A big advantage of overhead patio heaters is their heat efficiency. Since they stay in one place, you can angle or recess them exactly where you want warmth, which cuts down on wasted heat. This targeted control keeps things comfortable, even in tough weather.
Overhead heaters are also safer. In restaurants, busy areas, or homes with kids or pets, mounting heaters on the wall or ceiling prevents tipping and keeps hot surfaces out of reach. Some electric models can be recessed into the ceiling, making them almost invisible and a great match for modern spaces.
If you’re planning a long-term outdoor space like a covered dining area, lanai, pergola lounge, or four-season patio, overhead heaters offer the best look and performance. Most areas need more than one heater, so check each model’s coverage to plan your setup.
Free-Standing Patio Heaters: Flexible and Powerful Heating for Open Spaces
Free-standing patio heaters include popular mushroom-style propane heaters, permanent post heaters, and small tabletop units. They work well where you can’t mount overhead heaters or when you want extra heat at a lower level.
People like portable, free-standing heaters because they are simple to use and don’t need installation. Most run on 20-pound propane tanks that are easy to replace. They give off plenty of heat and can be moved around, which is great for parties or changing patio layouts. But since they spread heat in all directions, they are less efficient than overhead heaters and may use more fuel.
Permanent post heaters solve some of these issues. They are fixed into the ground, so they don’t take up as much space as portable models and can’t be tipped over. Restaurants and large patios benefit from their strength and flexible placement.
Tabletop heaters are a nice choice for small dining areas or cozy outdoor spaces. You can find them in electric or propane versions. They provide a gentle amount of heat, making them perfect for café tables, home patios, or extra warmth on bar counters.
Patio Heaters by Fuel Type
Electric Patio Heaters: Clean, Quiet, and Design-Forward
Electric patio heaters are ideal for enclosed patios, indoor-outdoor sunrooms, covered decks, and polished spaces. They produce zero emissions, require no venting, and are exceptionally safe—even in semi-enclosed locations where gas models may not be allowed.
People who care about design often choose electric heaters because they fit in easily with any space. Slim linear models, spot heaters, and recessed ceiling designs can be color-matched or powder-coated to match your décor.
You can control electric heaters easily. Some work with simple switches, apps, wall dimmers, or smart home systems. For businesses, centralized controls make things simple.
Electric patio heaters usually don’t get as hot as gas models and may need to be grouped together for bigger spaces. They often cost less up front and are easy to install. Your electricity rates affect running costs, and advanced controls can increase the price.
Gas Patio Heaters: High Heat Output and Superior Cold-Weather Performance
If you need strong heating, especially in cold climates, gas patio heaters are the best choice. For similar sizes, gas heaters often make three to five times more heat than electric ones. This makes them great for large patios, commercial spaces, events, or backyards where it gets very cold.
Natural gas patio heaters are popular with homeowners who want a permanent, low-cost heating option connected to their home’s gas line. They require professional installation, but natural gas offers the lowest running costs and steady heat. Liquid propane heaters are portable. From mushroom heaters to tabletops, propane models work almost anywhere, which is great for renters, people who entertain, or patios without built-in gas lines. Propane burns hot and steady but needs to be refilled.It consists but requires refills.
Some overhead gas heaters, like Calcana models, work even in very cold temperatures, down to –40°F. This makes them perfect for northern climates and for melting snow or ice.
Special Category: Pyramid Patio Heaters
Pyramid patio heaters are actually propane freestanding units, but they are more decorative than high-heat units. Their tall glass flame tubes create a warm glow and add style, but they don’t get as hot as regular mushroom heaters. The goal is ambiance first—and warmth second—a pyramid heater can be a visually stunning addition to your patio. Many Fire Goddess customers pair them with more powerful heaters. This creates the perfect blend of beauty and comfort.
Choosing the Right Patio Heater for Your Home
The best patio heater for you depends on your local weather, your style, your setup options, and how much heat you need.
If you want a permanent, integrated heating system, overhead electric or natural gas heaters offer the cleanest look. They also provide the most efficient heating pattern.
If you need flexibility and portability, freestanding propane heaters provide powerful warmth with no installation required.
If your space is enclosed or requires silent, emission-free operation, electric heaters are the safest and most attractive option.
If aesthetics are your priority and you want a beautiful fire feature, a pyramid heater adds instant ambiance.
Think about where your guests spend the most time, how big your heating area is, and if your heaters need to work well on cool fall nights or in the middle of winter.
Patio Heater Design Styles
Patio heaters come in many styles, from modern fixtures to classic mushroom shapes and decorative flame towers. Standing heaters work best in big outdoor areas, while mounted and hanging heaters save floor space. Tabletop heaters are great for small dining spots, and tank-top heaters are a tough, practical choice for workshops, campsites, or small patios.
Choosing a heater design that fits your space is as important as picking the right fuel. Think about your ceiling height, where people sit, what they’ll see, and if you want the heater to stand out or blend in.
Heat Output and Coverage
Different heaters cover different amounts of space. Gas models give off the most heat and can warm areas 15 to 20 feet wide or more. Electric heaters focus heat in smaller spots, so you may need several for bigger spaces.
BTUs, or British thermal units, measure how much heat gas heaters produce. Electric heaters use wattage instead. Higher numbers mean more heat, but where you put the heater, wind, and how high it’s mounted all affect how well it works. To get a rough estimate of BTUs needed to heat your space, take the square footage of your area and multiply by 20 to get an idea of the BTUs needed. For example, if your space is 250 square feet, multiply that by 20 to get 5,000 - the number of BTUs needed to heat that area. Also consider if the heater puts out heat in one direction or in a circular pattern.
General Clearances for Different Types of Heaters
Check the specific clearances in the specific manufacturers owners manual.
| Type of Heater | Top Minimum Clearance | Side Minimum Clearance | Bottom Minimum Clearance | Notes |
|---|---|---|---|---|
| Ceramic Radiant Heaters | 40–60 cm | 30–60 cm | 180–200 cm | Mount on the wall/ceiling using brackets |
| Electric Infrared Heaters | 30–50 cm | 20–40 cm | 180 cm | Best in semi-enclosed areas. |
| Gas-Fired Patio Heaters | 90–120 cm | 60 cm+ | Floor-mounted | Fully ventilated areas only |
Useful Features to Look For
Today’s patio heaters offer a range of features that improve performance, safety, and convenience.
Look for features like safety shutoff valves, CSA certification, smart controls, tip-over protection, quiet operation, remote controls, and the ability to use the heater indoors or outdoors. Some heaters are certified for very cold weather, so they work well in winter.
