Factors to Consider When Choosing the Right Outdoor Heater for Your Space
Choosing the right outdoor heater isn't just about picking the most powerful unit—it's about finding one that suits your space, lifestyle, and energy preferences. Here are the key points you should consider before buying:
1. Power Source
Electric: Cleaner and more convenient. Great for patios with nearby outlets.
Propane: Powerful and portable. Perfect for large spaces and flexible use.
Battery-Powered: Ideal for camping or multi-purpose use (e.g., EcoFlow WAVE 3).
2. Size and Coverage
Think about your layout: Are you heating a small balcony or a large garden? Check the BTU output or heat range for each model and match it to your seating setup.
3. Design and Safety
For family use, go for tip-over protection, flame guards, or wall-mounted models. If design is important, bronze or stainless steel finishes often work best in modern outdoor aesthetics.
4. Portability
Wheels make a difference, especially if you need to move the heater in and out of storage. Lightweight models are better for spontaneous gatherings or small patios.
5. Weather Resistance
Look for IP ratings (Ingress Protection) to ensure the unit can handle rain, wind, and temperature swings. Stainless steel and aluminum are top choices for durability.

FAQs
What type of heater is best for outdoors?
The best type of outdoor heater depends on your space and needs. Gas patio heaters are powerful and effective for larger areas, while electric infrared heaters are energy-efficient and provide targeted warmth without heating the air. For cosy gatherings, fire pits or chimineas offer both heat and ambience. If portability is important, freestanding gas heaters are versatile, whereas wall-mounted or ceiling-mounted infrared heaters suit fixed seating areas. Safety, budget, and the size of your outdoor space should guide the choice.
What outdoor heater puts out the most heat?
Gas patio heaters, particularly those fuelled by propane or natural gas, generally put out the most heat, with outputs reaching 10–15kW. They are effective for warming larger spaces or open areas and provide 360-degree heat distribution. By comparison, infrared electric heaters produce a more focused, radiant heat that warms people directly rather than the surrounding air. While gas heaters are better for heating larger groups, infrared heaters are efficient in smaller spaces where concentrated warmth is needed without energy wasted on the air.
Do outdoor heaters really work?
Yes, outdoor heaters work well, but their effectiveness depends on the type and conditions. Infrared electric heaters are highly effective in sheltered patios because they warm people directly, even when it's breezy. Gas patio heaters can cover larger open areas, providing noticeable warmth in cool evenings. However, in very cold or windy weather, no heater will make an outdoor space feel like indoors. Used properly, they extend outdoor living time into colder seasons, making gardens, patios, or terraces more comfortable for gatherings.
Are outdoor heaters expensive to run?
Running costs vary by type. Gas patio heaters (propane or natural gas) can be more expensive, often costing £1–£2 per hour depending on fuel prices. Electric infrared heaters are usually cheaper to run, costing around 15–30p per hour, depending on wattage and electricity rates. While gas heaters generate more heat for larger groups, they are less efficient. Electric heaters are more economical for smaller areas. Choosing an energy-efficient model and using timers or thermostats helps keep running costs manageable.
