7 Best Eco-Friendly Patio Heaters in 2025

As I researched the best environmentally friendly patio heaters for 2025, I noticed a huge gap. There aren’t any detailed guides on the safest patio heaters or information on how to choose the right option for your space. For that matter, even basic guidance seems to be lacking. So, for this round-up, I spent over three weeks researching, testing, and analyzing the most environmentally friendly outdoor heaters on the market. I evaluated different models, reached out to companies for clarifications, and reviewed reports for accuracy. Jump to the list>

Just because we are out in the open, that doesn’t mean that our health and the environment can’t be affected by our heating systems. It’s been proven multiple times that traditional patio heaters, especially those powered by propane or natural gas, release carbon emissions and contribute to air pollution. While they offer warmth, they come at an environmental cost. 

So much so that several countries have implemented regulations on patio heater usage. For instance, starting January 1, 2025, Barcelona banned gas-powered patio heaters to reduce carbon emissions. Similarly, France has prohibited heated outdoor seating areas, citing significant CO₂ emissions. 

If you’re wondering, about “environmentally friendly outdoor heaters”, the best options are electric infrared, solar-powered, and, lastly, wood pellet heaters.

How Do Patio Heaters Affect the Environment?

Patio heaters, while extending the comfort of outdoor spaces during cooler months, have notable environmental impacts. Their effects vary depending on the energy source and design, influencing carbon emissions, energy efficiency, and air quality.

They Emit Carbon Emissions

A standard propane patio heater consumes approximately 45,000 BTUs per hour. Operating such a heater for two hours can emit around 3 kilograms of CO₂, contributing to greenhouse gas accumulation. That’s A LOT of CO₂ for a cozy night in the backyard.

Natural gas heaters also emit CO₂, though specific emission data varies based on usage and heater efficiency. While natural gas burns cleaner than propane, it remains a fossil fuel with a significant carbon footprint. It’s a no from me for sure.

The environmental impact of electric heaters depends on the electricity source. If powered by renewable energy, their operation results in minimal direct emissions. However, if the electricity is generated from fossil fuels, the associated CO₂ emissions can be substantial. So, while electric is the best eco-friendly patio heater type, you should be very mindful of the source.

Energy Efficiency Isn’t Always Good

Propane and natural gas heaters are notorious for losing a significant portion of the generated heat to the surrounding air, especially in open spaces, making them less energy-efficient. A typical gas-powered patio heater might use up to 108 megajoules (MJ) of energy in just a couple of hours. Despite the evidence, these two types continue to be perceived as the “most reliable patio heaters” by many consumers due to the marketing gimmicks. 

If you want a truly environmentally friendly patio heater, electric infrared heaters are the way to go. They are more efficient in outdoor settings as they directly warm objects and people rather than the air. This targeted heating approach reduces energy waste. An efficient electric system would use about one-fifth of the energy compared to a gas heater for the same heating duration.

Patio Heaters Affect Air Quality and Pollutants

Burning wood releases particulate matter and pollutants such as nitrogen oxides (NOₓ) and volatile organic compounds (VOCs), which can degrade air quality and pose health risks. The World Health Organization estimates that around 7 million premature deaths annually can be linked to air pollution, with wood combustion being a notable contributor. That’s a risk I am not willing to take.

Gas heaters are not the most non-toxic patio heater option either. While cleaner than wood-burning options, propane and natural gas heaters still emit pollutants, including CO₂ and NOₓ, affecting both environmental and human health.

So, now is more important than ever to opt for a truly safe eco-friendly patio heater. So let’s evaluate all the possible options.

The Different Types of Outdoor Patio Heaters Explained

When the cold creeps in, patio heaters step up to keep outdoor spaces warm and inviting. But not all heaters work the same way—or have the same impact on the environment. Some run on fossil fuels, others use electricity, and a few go old-school with fire.

For over 20 years, I’ve relied on patio heaters to keep my summer home’s outdoor space warm and cozy. Some of my best memories include sitting under the night sky, wrapped in a blanket, watching the stars twinkle. But I also remember the odd smell—most likely from a gas-powered heater—lingering in the air. Back then, I didn’t think much of it. Now, I know better.

Let’s break down the main types, how they work, and what makes them tick.

Gas Patio Heaters (NOT SAFE)

Gas patio heaters are what you’ll often see in restaurants, cafes, and backyards. They run on either propane or natural gas, producing steady, reliable warmth. But while they’re effective, they’re not exactly the most environmentally friendly outdoor heaters out there. They come in two different types.

Propane Heaters

Propane heaters are the most common because they’re portable and easy to use. Just connect a propane tank, hit the ignition, and you’ve got heat in seconds. No cords, no wiring—just instant warmth. But they are far from being safe or environmentally friendly patio heaters in 2025. Burning propane releases carbon dioxide (CO₂), contributing to greenhouse gas emissions. Plus, those fuel tanks need regular refills, which adds cost and hassle.

Natural gas patio heaters

Natural gas heaters, on the other hand, connect directly to a home’s gas line. That means no refills, no tanks—just continuous heat at the turn of a knob. They’re usually more cost-effective in the long run but require professional installation. And since natural gas is still a fossil fuel, it’s not exactly the safest patio heater option.

Gas heaters work by either producing an open flame (like a giant outdoor torch) or using a ceramic element that radiates heat. They warm the surrounding air, creating a cozy heat bubble. The problem? A lot of that heat escapes into the atmosphere. So they are not the most efficient patio heater option out there.

Electric Patio Heaters (SAFEST)

Electric patio heaters are a solid alternative for those looking to reduce emissions. Unlike gas heaters, they don’t burn fuel or release CO₂ directly into the air. Instead, they run on electricity—so if you’re using renewable energy, they can be a much greener option.

Infrared Heaters

Most electric heaters use infrared technology, which works differently from traditional heating. Instead of warming the air, infrared waves heat people and objects directly—like the sun on a cool day. That means no wasted energy floating away in the breeze. This makes them more efficient, especially in open outdoor spaces. This is by far the Best eco-friendly patio heater option in 2025.

Quartz Heaters

Quartz heaters are another type of electric heater, that uses a quartz element to generate intense, focused heat. You can safely use them as an outdoor heater for covered patios. But keep in mind that they work better for smaller patios where you need concentrated warmth.

Wall-Mounted or Free-Standing

You’ll find electric heaters in different styles, including wall-mounted models that save space and free-standing ones that you can move around. Some freestanding electric patio heaters even come with motion sensors or timers to reduce unnecessary energy use.

While electric heaters have a lower carbon footprint than gas models, they’re only as green as the power source they rely on. If your electricity comes from coal, the environmental benefits shrink. But if you’re hooked up to solar or wind energy? You’re golden.

Wood-Burning Patio Heaters 

There’s something undeniably charming about a crackling fire on a chilly night. Wood-burning patio heaters bring that rustic vibe, whether it’s a fire pit, a chiminea, or a wood pellet heater. But while they score high on ambiance, they’re not always the best for air quality.

Fire Pits & Chimineas (NOT SAFE)

Traditional fire pits and chimineas burn logs or charcoal, creating a beautiful (but smoky) heat source. They release carbon emissions along with particulates, which can contribute to air pollution. If you love the idea of a real fire, choosing seasoned hardwood or compressed logs can help reduce smoke.

Pellet Heaters

Wood pellet heaters offer a cleaner-burning alternative. These heaters use compressed sawdust pellets, which produce less smoke and burn more efficiently than regular wood. Some models even include fans to distribute heat more evenly. While they still emit CO₂, they’re considered carbon-neutral because the trees used for pellets absorb CO₂ as they grow. So, if you aren’t a fan of infrared heaters, this is the second-best option for environmentally friendly patio heaters.

One of the biggest downsides of wood-burning heaters? They require more effort. You’ll need to keep a steady supply of wood or pellets, and cleaning up ash is part of the deal. Plus, in some areas with air quality regulations, using a wood-burning heater may not be allowed.

So, What is the Most Environmentally Friendly Patio Heater?

Infrared Electric Heaters 

Infrared electric heaters are hands down the most eco-friendly option—when powered by renewable energy. They work by emitting infrared waves that heat objects and people directly, instead of wasting energy warming the air. This means zero emissions, instant warmth, and less energy waste.

Why They’re the Best:

• No Carbon Emissions (when using clean electricity)
• Up to 90% Energy Efficient—more heat, less waste
• No Open Flame or Fuel Consumption
• Works Well in Open Spaces (heat isn’t lost to the wind)

If your electricity comes from renewable sources (solar, wind, hydro), infrared heaters have virtually no environmental impact. But if your grid runs on fossil fuels, they’re only as green as the energy behind them.

Wood Pellet Heaters 

If you love the cozy vibe of a fire but want a cleaner burn, wood pellet heaters are a solid option. Unlike traditional wood-burning heaters, these use compressed sawdust pellets, which burn hotter and release fewer pollutants. Since the wood used for pellets comes from sustainable sources, they’re often considered carbon-neutral.

 Why They’re a Good Option:

• Burns Cleaner Than Firewood (less smoke, fewer particulates)
• Pellets Are Made from Waste Wood (no trees cut down just for fuel)
• More Efficient Than Traditional Wood Fires

Just be sure to use certified sustainable pellets to avoid contributing to deforestation.

BONUS: Heated Outdoor Furniture 

Want to skip the heater altogether? Instead of wasting energy warming the air, heated outdoor furniture heats you directly by using low-energy heating elements built into chairs, benches, and tables.

Why They’re the Future:

• Uses 80% Less Energy Than Traditional Patio Heaters
• Zero Emissions (especially when paired with solar panels)
• Heats People, Not Empty Space

NON-Eco-Friendly Outdoor Heaters To Avoid 

Propane & Natural Gas Heaters – These release carbon dioxide and other pollutants, making them a major contributor to climate change. Even though they provide strong heat, they waste energy by warming the air around them.

Traditional Fire Pits & Wood-Burning Stoves – While they create an unbeatable ambiance, they release a ton of smoke and particulates. In areas with poor air quality, they can actually be a health hazard.
