Infrared Patio Heaters vs. Propane Tower Heaters: Complete Comparison

When you're planning a patio upgrade, choosing between infrared and propane tower heaters is one of the biggest decisions you'll make. Both heat your outdoor space, but they work in completely different ways—and that difference affects everything from comfort level to long-term costs. We've worked with homeowners choosing between these options for years, and the answer really depends on what you need from your outdoor space.

How They Work: The Core Difference

Let's start with the fundamental technology. Propane tower heaters—also called mushroom heaters or dome heaters—work like mini space heaters. They burn propane gas and create convection heat, warming the air around them. You feel the warmth radiating downward from the top of the unit.

Infrared heaters, like the models we carry from Bromic, work completely differently. They emit infrared radiation—the same type of heat you feel from the sun. Instead of warming the air, infrared heat warms objects and people directly. Think of standing in sunlight on a cool day; you feel warm even though the air temperature hasn't changed much.

Heat Output and Coverage Area

This is where the comparison gets practical. Propane tower heaters typically output between 40,000 and 50,000 BTU, with some high-end models reaching up to 87,000 BTU. They create a circular heating zone directly beneath them.

Bromic infrared heaters deliver between 22,000 and 40,000 BTU depending on the model, but here's the key: they're more efficient at converting energy into usable heat. A 40,000 BTU infrared heater often feels warmer and covers area more effectively than a 50,000 BTU propane tower because there's less energy wasted heating the air itself.

Coverage depends on your setup. Propane towers work best when people are clustered directly under or very close to them. Infrared heaters perform better when spread across an area, as each unit radiates outward in a broader pattern. If you have a dining area 15 feet long, you might prefer two infrared heaters spaced apart over one tower heater.

Operating Costs and Efficiency

Let's talk money, because this is where the decision often gets made. Propane costs vary by region, but figure roughly $2–$4 per gallon. A 50,000 BTU tower heater running for 4 hours a night might use $4–$8 worth of propane per evening during season.

Infrared heaters are roughly 30–40% more efficient at converting fuel to usable heat. That means a Bromic infrared unit delivering the same comfort level might run $2–$5 per evening. Over a 4-month season with regular use, that's several hundred dollars in savings.

There's also the equipment cost to consider. Quality infrared heaters typically cost $400–$1,200 depending on power source and features. Propane tower heaters range from $300–$800. So the infrared upfront investment pays for itself within 1–2 seasons through fuel savings.

Wind Performance and Effectiveness

Here's where propane heaters struggle: wind. A breeze above 10 mph significantly reduces the heating coverage of a propane tower because the convection heat gets blown away. In windy climates, you're essentially pouring money into the sky.

Infrared is the clear winner in wind. Because infrared heat travels as radiation rather than hot air, wind has minimal impact on performance. Even on breezy evenings, your Bromic infrared heater delivers consistent warmth. If you're in a coastal area or your patio catches afternoon winds, this matters enormously.

Aesthetics and Installation

Propane tower heaters have a distinctive look—the large dome or mushroom shape is iconic for patios. They're instantly recognizable and some people love that classic aesthetic. They also require minimal installation; you place them on a flat surface and connect the propane tank.

Infrared heaters offer more design flexibility. Wall-mounted Bromic units integrate seamlessly into pergolas or modern outdoor kitchens. Freestanding models are sleeker and more contemporary. Hanging models work well over dining tables or seating areas. If your outdoor space is an extension of your home's design, infrared gives you more styling options.

For an outdoor kitchen setup with a Summerset grill or Fire Magic components, infrared heaters often coordinate better aesthetically than a bulky propane tower.

Fuel and Maintenance

Propane towers are straightforward: swap the tank when empty. Maintenance is minimal—maybe wipe down the cover occasionally.

Infrared heaters require a few considerations. Wall-mounted or overhead units need proper electrical installation by a professional—plan on $300–$500 in installation costs for permanent models. Portable Bromic units might use propane cartridges or electric options. There's slightly more setup, but once installed, they're equally low-maintenance.

Weather Durability and Winterization

Both types handle outdoor weather well when covered. Propane towers are tanks with simple mechanics, so they age gracefully. Quality infrared units like Bromic are built with stainless steel and weatherproof materials designed for years of exposure.

Winterization is similar for both: cover when not in use, drain hoses if applicable (for some electric infrared models), and store tanks in a cool, dry location.

Electric vs. Propane Infrared Options

Bromic and other infrared brands offer both propane and electric models. Electric infrared is becoming increasingly popular because it eliminates fuel costs entirely—you only pay the electricity to run it, usually $0.50–$1.50 per evening. However, you need a nearby outlet and potentially a certified electrician for installation.

Electric infrared works especially well for year-round patio spaces or built-in outdoor kitchens where a permanent connection makes sense.

Which Should You Choose?

Choose a propane tower heater if:

• You want minimal installation hassle
• You have a calm, sheltered patio (wind isn't a factor)
• You like the classic mushroom heater look
• You're budget-conscious on upfront cost
• You heat only occasionally in winter

Choose an infrared heater (like Bromic) if:

• Your patio experiences regular wind
• You want better fuel efficiency and lower operating costs
• You heat frequently or for longer periods
• Your outdoor design is modern or contemporary
• You're integrating with a full outdoor kitchen setup
• You have electricity available and want the lowest fuel costs

Combining Heaters for Maximum Comfort

Here's a pro tip: you don't have to choose just one. Many premium outdoor kitchens combine heaters strategically. A wall-mounted Bromic infrared heater over a dining table ensures consistent warmth, while a propane tower in a separate seating area provides ambient heat. This approach gives you the best of both worlds and multiple heating zones.

Integration with Your Outdoor Kitchen

If you're building a full outdoor kitchen with appliances from Fire Magic, Summerset, TrueFlame, or other top brands, heating choices matter. Infrared units integrate more seamlessly with modern kitchen designs, and their efficiency means your patio stays comfortable year-round without excessive costs.

FAQ: Infrared vs. Propane Heaters

Do infrared heaters work in cold weather?

Yes, infrared heaters work well in cold weather. Unlike propane convection heaters, they're not dependent on warming the air, so they're effective even when it's freezing. You'll feel warm even when the ambient temperature is low.

Can you use a propane tower heater in a covered patio?

No. Propane heaters produce carbon monoxide and should never be used in enclosed or covered spaces. Infrared heaters also shouldn't be used under solid covers, though some models are rated for use under open pergolas or partial coverage. Always check your heater's specifications.

How much does it cost to run each heater nightly?

A 50,000 BTU propane tower costs roughly $4–$8 per night. A comparable Bromic infrared heater costs $2–$5. Over a 4-month season (assuming 4 hours per night), that's $500–$1,000 difference, which pays for the heater's price difference within 1–2 seasons.

Which heater is safer for families with kids?

Both require safety precautions, but infrared heaters eliminate some risks. There's no open flame, no carbon monoxide concern in covered spaces, and the surface temperature is lower. That said, all outdoor heaters should be positioned where children can't accidentally touch them or play nearby.

Do infrared heaters look as good as tower heaters?

It depends on your style. Modern outdoor kitchens look better with sleek Bromic infrared heaters. Traditional patios might prefer the classic mushroom heater aesthetic. Both have their place.
