Pellet patio heater: the complete guide to outdoor heating
A pellet patio heater is an outdoor stove that runs on wood pellets. No electricity, no gas bottle — you fill the reservoir with pellets, light the fire starters with the gas lighter, and within minutes you enjoy a real flame and tangible radiant heat. Exactly the warmth you want on cool evenings outdoors.
In this guide, you will find everything you need to know before buying a pellet patio heater. From the advantages over gas and electric, to choosing the right model for your patio or covered terrace.
Why choose a pellet patio heater?
There are three ways to heat your patio: gas, electric, or pellets. Each has its merits, but more and more people are choosing pellets. Here are the five reasons we hear most often.
A real flame, a real atmosphere
A gas patio heater with a reflective dome gives heat, but no fire feeling. An electric heater even less so. A pellet patio heater burns with a visible, real flame inside a heat-resistant glass tube. That flame display makes all the difference: you are not just warm, you are in good company.
No electricity, no gas bottle
A pellet patio heater works entirely without electricity and without a gas bottle. No cables across the patio, no heavy gas cylinders to carry. You are free to place the heater wherever you like — even where there is no power outlet nearby.
Hardly any smoke, hardly any ash
Quality wood pellets (ENplus A1 certified, 6 mm, maximum 8% moisture) burn very cleanly. In practice, our customers are surprised by how little smoke and ash is produced. The result is low-smoke — not completely smoke-free, but with the right pellets you barely notice it.
More affordable than gas in the long run
A 15 kg bag of pellets costs a fraction of a gas bottle. While we do not quote an exact cost per hour — that depends on your flame height and pellet brand — our customers are clear: pellets are cheaper to run than gas.
More sustainable than the alternatives
Wood pellets are a renewable fuel, pressed from by-products of the timber industry (sawdust, wood shavings). The CO₂ released during combustion is the same CO₂ the tree absorbed while growing. This makes a pellet patio heater significantly more sustainable than gas or a mains-powered electric heater.
What to look for when buying a patio heater
Not every patio heater suits every patio. Before you buy, consider these five points.
1. The size of your outdoor space
Have a compact balcony or city garden? A smaller heater fits better than a 220 cm model. For a large terrace or hospitality setting, you want a taller model with more presence and heat range.
2. Covered or open air?
A pellet patio heater is suitable for well-ventilated outdoor spaces — including a semi-open or open covered terrace. A fully enclosed space (such as a conservatory with closed doors) is not suitable. Maintain a minimum clearance of 40 to 50 cm around the heater.
3. Portability
Do you want to move the heater regularly — from the patio to the front garden, for example? Choose a model with wheels and a handle. If the heater stays in one spot, the design or an integrated table matters more than mobility.
4. Design and functionality
Some patio heaters have an integrated table top — handy for a glass of wine or a candle. Others focus purely on the flame display. Choose what suits your patio setup.
5. Budget
A pellet patio heater is an investment. You are not buying a disposable product, but a robust outdoor heater made of powder-coated steel with heat-resistant glass. Browse the full collection for current models and pricing.
Which pellet patio heater is right for you?
Flamesa makes four pellet patio heater models, each designed for a different situation. The table below shows the key differences at a glance.
| Model | Type | Height | Key feature |
|---|---|---|---|
| Avara | Compact | 122 cm | Pellet stopper, light and small |
| Flare | Mobile | 175 cm | Wheels and handle, portable |
| Lumina | Design with table | 175 cm | Integrated steel table top |
The right patio heater for your situation
Small balcony or city garden — Avara
The Avara at 122 cm is the most compact pellet patio heater. Ideal when space is limited but you still want a real flame and warmth. The pellet stopper prevents pellets from spilling if the heater is tilted.
Flexible use — Flare
The Flare has wheels and a handle, making it easy to reposition. From the patio to the front garden, or to a party at the neighbours'. Perfect when the heater does not always stay in the same spot.
Design and dining terrace — Lumina
The Lumina combines a patio heater with an integrated steel table. Set your glass on it, add a candle — the Lumina is designed for terraces where ambience and function come together.
How to get the most from your patio heater
Use the right pellets
Always use ENplus A1 certified wood pellets (6 mm, max 8% moisture, max 0.7% ash, min 4.6 kWh/kg). Quality pellets are the single most important factor for clean combustion and a beautiful flame. Store them dry — pellets are hygroscopic and absorb moisture from the air.
Position the heater correctly
Place the patio heater on a stable, level surface. Maintain at least 40 to 50 cm clearance all around. On a wooden deck, use a heat-resistant mat. A sheltered spot gives better flame height and less smoke.
Light it properly
Use fire starters (wood wool) and the gas lighter — not firelighter cubes. Place the starters in the pellet reservoir, light them, and let the pellets catch fire on their own. Within a few minutes the flame reaches its normal height.
Clean regularly
Every two to three sessions, remove the ash with a compact ash vacuum or brush. Clean the glass with a cleaning kit. This keeps the flame display clear and the heater burning at its best.
Store properly
Use a protective cover when the heater is not in use for an extended period. Store it dry if possible — under a covered area or in a shed. The powder-coated steel is weather-resistant, but prolonged exposure to rain shortens its lifespan.
Your pellet patio heater through the seasons
A pellet patio heater is not just for autumn. In practice, our customers use their heater year-round — whenever the evenings are cool enough to warrant it.
Spring and summer
On fresh spring evenings and in late summer, when temperatures drop after sunset, a pellet patio heater is ideal. You sit outside with a real flame and the warmth keeps you comfortable without having to retreat indoors. A lower flame setting provides enough warmth and a longer burn time.
Autumn and early winter
This is the season when a pellet patio heater truly comes into its own. Falling leaves, a glass of wine, and a real flame on the terrace — this is exactly what the product was designed for. On colder evenings, turn the flame higher and move the chairs closer to the heater.
When a pellet patio heater is not the best choice
We want to be upfront: a pellet patio heater is not the best solution for every situation. Here is when to consider an alternative.
Fully enclosed spaces
A pellet heater is designed exclusively for well-ventilated outdoor spaces. In a sealed conservatory with closed doors or a fully enclosed garden room, a pellet heater is not suitable. Electric heating is safer in those cases.
Pure background heat only
A pellet patio heater gives radiant heat — warmth you feel when sitting nearby, similar to the warm sensation next to a campfire. It does not heat an entire space evenly like central heating. If you only want to warm a space without the fire experience, an electric heater is more practical.
No interest in maintenance
A pellet heater needs basic maintenance: removing ash, cleaning the glass, refilling pellets. If you prefer something that works at the push of a button, an electric heater is a better fit. But if you enjoy the ritual of making a fire, that maintenance is part of the experience.

Frequently asked questions about pellet patio heaters
What is a pellet patio heater?
A pellet patio heater is an outdoor stove that runs on wood pellets. You fill the reservoir, light the fire starters, and enjoy a real flame and radiant heat. No electricity or gas bottle is needed. The heat is noticeable up to several metres away — it warms the people around it, not the entire outdoor space.
Can I use a pellet patio heater under a covered patio?
Yes, provided the cover is well-ventilated — semi-open or open on at least one side. A fully enclosed space such as a conservatory with closed doors is not suitable. Always maintain at least 40 to 50 cm clearance around the heater.
How much smoke does a pellet patio heater produce?
With the right pellets (ENplus A1, dry, 6 mm), a pellet heater is low-smoke. During lighting there may briefly be a little more smoke, but once the flame is stable, smoke production is minimal. Not entirely smoke-free, but in practice most users barely notice.
Which pellets should I use?
Always use ENplus A1 certified wood pellets (6 mm, max 8% moisture, max 0.7% ash, min 4.6 kWh/kg). Always store them dry. Poor or damp pellets produce more smoke, less flame, and more ash.
How long does a pellet patio heater burn?
Burn time depends on the model and flame height. With a full fill of 15 kg of pellets, you can typically enjoy an entire evening. A lower flame setting gives a longer burn time.
Is a pellet patio heater suitable for a small balcony?
Yes. The Avara is specifically designed for compact outdoor spaces. At 122 cm tall with a small footprint, it fits most balconies, provided there is sufficient ventilation and the 40 to 50 cm clearance guideline is observed.
Do I need to winterise a pellet patio heater?
After the season, remove all ash, clean the glass, and cover the heater with a protective cover or store it in a dry place. The powder-coated steel is weather-resistant, but prolonged exposure to rain and frost shortens its lifespan. With proper care, a pellet patio heater lasts for many years.
