Bromic Tungsten Smart-Heat
Best OverallPros
- Smart app and remote control
- IP65 weather resistant
- Instant infrared heat
Cons
- Requires hardwiring or outlet
- Premium price point
The Bromic Tungsten Smart-Heat is a wall or ceiling mounted electric heater that uses infrared technology to warm people and objects directly, not the air. With 5,200 BTUs, it covers up to 200 square feet efficiently and is rated IP65 for outdoor use, meaning it withstands rain and dust.
Owner reviews highlight its sleek, low-profile design and the convenience of the smart app for scheduling and dimming. The main drawback is the installation requirement, as it needs a dedicated electrical circuit, but the build quality and warranty support from Bromic justify the investment for permanent setups.
Amazon Basics 46,000 BTU Patio Heater
Best BudgetPros
- Very affordable price
- High heat output
- Easy to assemble
Cons
- Propane tank not included
- Shorter lifespan than premium models
The Amazon Basics 46,000 BTU Patio Heater is a classic propane tower heater that delivers powerful heat for a fraction of the cost of other brands. It features a stainless steel burner and a safety tip-over shutoff, making it a practical choice for renters or occasional use.
Aggregated reviews praise its quick heating and sturdy base, but some note that the finish can show wear after a season. For the price, it offers the highest BTU per dollar, making it ideal for warming a standard 10x20 patio without breaking the bank.
Lava Heat Italia LPG
Best Design & PortabilityPros
- Stylish Italian design
- Lightweight and portable
- Adjustable heat settings
Cons
The Lava Heat Italia LPG is a portable propane heater that combines aesthetics with functionality. Its powder-coated steel body and bronze finish make it a standout piece on any patio, while the 11,000 BTU output is sufficient for small gatherings on a deck or balcony.
Owner feedback consistently mentions the easy portability and the adjustable heat dial, which allows for low, medium, and high settings. The trade-off is its limited range, so it works best as a close-proximity heater for a dining table or seating area of up to 100 square feet.
Fire Sense Commercial 46,000 BTU
Best for Large PatiosPros
- Commercial-grade build
- Wide heat dispersion
- Durable stainless steel
Cons
- Heavy and less portable
- Higher fuel consumption
The Fire Sense Commercial 46,000 BTU heater is built for larger outdoor areas, featuring a polished stainless steel reflector and a heavy-duty base. It uses a standard 20 lb propane tank and has a piezo ignition system for easy lighting, with a safety shutoff valve.
Reviews from owners with large patios or decks note that it effectively warms areas up to 250 square feet, even in light wind. The main downsides are its weight and the fact that it uses propane more quickly than smaller units, but the robust construction and consistent heat output make it a favorite for frequent entertainers.
Patio Shield by Lasko
Best TabletopPros
- Compact and lightweight
- Plug-and-play electric
- Tip-over safety switch
Cons
- Limited coverage area
- Not for windy conditions
The Patio Shield by Lasko is an electric tabletop heater designed for close-range warmth on small patios, balconies, or during outdoor dining. It features a quartz infrared element and a self-regulating thermostat, with a simple on/off switch and a built-in safety tip-over switch.
Owner reviews appreciate its portability and the fact that it requires no fuel or assembly. The main limitation is its range, as it only effectively heats a small area directly in front of it, making it best for personal use on a table rather than warming a whole space.
What to Check Before Buying a Patio Heater
Before purchasing, you need to evaluate three core factors: fuel type, heat output (BTU), and the physical space you want to heat. Each factor directly impacts running costs, installation, and effectiveness.
Fuel type is the first decision. Propane heaters offer portability and high BTUs but require tank refills and ventilation. Electric models are cleaner and cheaper to run but need an outlet and have lower peak heat. Natural gas units connect to your home's gas line, offering unlimited run time but require professional installation.
BTU (British Thermal Units) measures heat output. A general rule is 5,000 BTU per 100 square feet for mild warmth, but you may need more in open or windy areas. For a standard 200 square foot patio, look for at least 40,000 BTU in a propane unit or 5,000+ BTU in an electric infrared model.
Space and mounting matter. Freestanding tower heaters are easy to move but take up floor space. Wall or ceiling mounted units save room and provide even heat but require installation. Tabletop heaters are best for small, intimate settings.
Mistakes to Avoid
Buying too low a BTU is the most common error. A 5,000 BTU electric heater will not warm a large, open deck. Always measure your square footage and add 20% for windy conditions.
Ignoring safety features can be dangerous. Always choose models with tip-over shutoff, overheat protection, and a stable base. For propane units, ensure the gas connection is secure and the unit is kept away from flammable materials.
Forgetting about wind reduces effectiveness. Patio heaters work best in sheltered areas. If your space is exposed, consider a model with a wind guard or a higher BTU output to compensate for heat loss.
FAQs
What size patio heater do I need for a 200 square foot patio?
For a 200 sq. ft. patio, a propane heater with 40,000 to 46,000 BTU is recommended, or an electric infrared model with at least 5,000 BTU for covered areas.
Is propane or electric patio heater better?
Propane is better for high heat output and portability in open spaces, while electric is cheaper to run, safer, and ideal for covered patios with access to an outlet.
Can I use a patio heater under a covered porch?
Yes, but ensure the heater is rated for outdoor use and has at least 3 feet of clearance from the ceiling. Electric infrared models are safest for covered areas.
How long does a 20 lb propane tank last on a patio heater?
A 20 lb propane tank typically lasts 8 to 12 hours on high heat for a 46,000 BTU heater, depending on the outdoor temperature and wind.
Do patio heaters work in windy conditions?
They are less effective in wind, as heat disperses quickly. Using a wind guard or placing the heater in a sheltered area improves performance.
What is the safest type of patio heater?
Electric patio heaters are generally the safest because they do not produce carbon monoxide and have no open flame, but all types should have tip-over shutoff.
How much does it cost to run a patio heater per hour?
Electric heaters cost about $0.10 to $0.30 per hour, while propane heaters cost $0.50 to $1.00 per hour depending on local gas and electricity rates.
Can I leave a propane patio heater on overnight?
It is not recommended to leave any propane heater unattended overnight due to fire and carbon monoxide risks. Always turn it off before sleeping.
Do I need a cover for my patio heater?
Yes, a weather-resistant cover extends the life of your heater by protecting it from rain, dust, and UV damage when not in use.
What is the difference between infrared and convection patio heaters?
Infrared heaters warm objects and people directly, providing instant heat, while convection heaters warm the air, which takes longer but can heat a larger area.
Our verdict
For most homeowners, the Bromic Tungsten Smart-Heat offers the best balance of efficiency, design, and smart features for covered patios. If you need a budget-friendly option for open spaces, the Amazon Basics 46,000 BTU Patio Heater delivers the highest heat output per dollar and is a reliable choice for occasional use.
