Outdoor Heaters for Restaurants: What to Buy for a Heated Patio

Picture a Friday in late October. The dining room is full, the patio is empty, and guests keep glancing at the heat lamp that was supposed to solve the problem. For a restaurant owner, outdoor heating is not a luxury; it is the difference between thirty usable seats and sixty during the shoulder seasons. The right heater extends the patio calendar by months, but the wrong one wastes fuel, trips fire inspections, or leaves guests shivering ten feet away.

Restaurants face constraints that backyard hosts do not: fire codes, insurance rules, staff handling, and customers who judge the whole venue by the patio. As of 2026, propane towers, electric infrared units, and portable propane heaters remain the three practical families. The picks below cover each style, and the buying rules explain clearance distances, fuel logistics, and how to confirm local code before anything is delivered.

Quick Picks

How to Choose

Start with fire code and fuel rules

Before comparing models, call the local fire marshal. Many cities restrict propane near awnings, tents, and building walls, and some require a minimum distance of several feet from combustibles. A good rule of thumb is to treat the manufacturer’s clearance chart as the minimum and your inspector’s rule as the final word. Insurance carriers may also require listed equipment and trained staff.

Ask your insurance agent for the carrier’s requirements in writing, since some policies exclude open-flame equipment unless the unit carries a specific safety listing. Keep the heater’s manual, listing label, and inspection notes in a binder at the manager’s station. When an inspector or adjuster asks for proof, having the paperwork ready saves a day of delays and keeps the patio open on busy weekends.

Size the heat to the area

One tower heater generally warms a circle around 15 to 20 feet across in still air, and wind shrinks that quickly. Plan one heater per two to four tables, placed so no guest sits closer than a few feet. Output is measured in BTUs for propane and watts for electric; commercial propane towers commonly run around 40,000 BTUs, while infrared electric units range from 1,500 watts upward.

Walk the patio on a cold evening before you buy and note where wind funnels between buildings or off a parking lot. Windbreaks such as clear panels, planters, or screens can improve heat retention more than adding an extra heater. Guests seated along a wall usually feel warmer than those in the open center, so place heaters where the cold complaints come from, not where the layout looks tidy.

Decide between propane and electric

Propane is mobile and needs no wiring, but tanks need refilling, safe storage, and trained handling. Electric infrared heaters are cleaner and quieter, and they suit covered or permanent installations, but they need proper circuits and often a licensed electrician. Choose propane for flexibility; choose electric for a fixed, tidy patio.

Think about the daily routine too. Propane towers must be lit, checked, and shut down by someone every service, and cylinders must be swapped by trained staff, usually before opening. Electric units switch on from a wall control and need almost no daily labor, which matters for restaurants running a lean crew. Estimate the weekly hours of handling before deciding that the lower equipment cost of propane is really cheaper.

Check safety features and stability

Look for a tip-over shutoff, a flame-out safety valve, and a wide, weighted base on freestanding models. Heaters must be CSA or UL listed for the way you plan to use them. In windy areas, pick a stable base or secure the unit to the deck. If your patio also includes comfortable seating such as an outdoor patio sectional, keep cushions well away from the heat head.

Finally, plan for the off-season. Covers keep dust and moisture out of burners, while a dry indoor closet protects regulators and hoses from cold cracking. Mark each heater with a number and log inspection dates, so a failed unit is easy to pull from service without disrupting the whole patio.

Heaters Reviewed

Fire Sense Pyramid Patio Heater

Fire Sense sells a long line of patio heaters, and the pyramid style is a familiar sight outside restaurants and bars. Its glass-tube flame is a visual draw as well as a heat source, which matters when the patio is part of your atmosphere.

• Pro: pyramid-style propane towers radiate heat in a wide circle, suiting open patios with spaced tables.
• Pro: freestanding units can be moved around as the seating plan changes.
• Con: propane towers need regular tank changes, and staff must handle cylinders safely.

Who should skip it: venues under low awnings or tents, where propane towers may be prohibited, and operators who dislike managing fuel.

Hiland Tall Propane Patio Heater

Hiland is a staple name in patio heating, and this tall propane model follows the classic freestanding tower format. Tall designs raise the heat source above table height, which spreads warmth over a wider area than a short unit.

• Pro: tall freestanding construction lets heat reach multiple seats at once.
• Pro: propane means no electrical work, so you can place heaters wherever the patio layout needs them.
• Con: tall towers are top-heavy, so wind and customer bumps are real concerns.

Who should skip it: windy rooftops, tight patios with narrow walkways, and operators who need a permanent, tidy installation.

Dr. Infrared Heater DR-238

Dr. Infrared Heater makes electric infrared units, and the DR-238 is sold as an outdoor-capable model. Infrared heat warms people and objects directly rather than the air, which is why it suits covered patios where wind is limited.

• Pro: electric infrared avoids propane tanks, which simplifies storage and staff training.
• Pro: quiet operation keeps the patio atmosphere pleasant for diners.
• Con: electric units require proper wiring and capacity, and mounted installs may need an electrician.

Who should skip it: fully open, windy patios, where infrared heat disperses, and restaurants without electrical capacity on the patio.

Bromic Tungsten Smart-Heat Electric Outdoor Heater

Bromic is a brand strongly associated with commercial and high-end outdoor heating. The Tungsten Smart-Heat Electric is an electric radiant heater meant for permanent mounting, which is a different proposition from a rolling tower.

• Pro: a mounted electric heater frees up floor space, which matters on tight patios.
• Pro: a commercial-focused brand typically offers guidance on layout, mounting, and electrical needs.
• Con: permanent installation costs time and planning, and the unit cannot be moved on a whim.

Who should skip it: seasonal pop-up patios, renters who cannot mount fixtures, and anyone who needs flexible placement.

Mr. Heater Big Buddy Portable Propane Heater

Mr. Heater is best known for portable propane heaters, and the Big Buddy is among its most recognized. It works as a flexible spot heater for small areas, such as staff break zones, a covered host stand, or a sheltered corner.

• Pro: portable propane format moves wherever you need warmth without wiring.
• Pro: compact size fits small spaces where a tall tower would not.
• Con: portable heaters are not designed to warm a whole patio of paying guests.

Who should skip it: operators needing guest-facing coverage over a large area, and any venue whose fire code does not allow portable propane near diners.

Which One Fits

• Wide-open patio with spaced tables: Fire Sense Pyramid Patio Heater or Hiland Tall Propane Patio Heater.
• Covered pergola with electrical service: Dr. Infrared Heater DR-238.
• Permanent, tidy upscale patio: Bromic Tungsten Smart-Heat Electric Outdoor Heater.
• Staff areas and small corners: Mr. Heater Big Buddy Portable Propane Heater.
• Evening lighting for the same patio: pair heaters with a schedule from an outdoor light timer so ambient lights come on as the heat does.

Many operators mix types: electric units along a covered wall where code allows only electric, and propane towers in the open center, with a portable unit kept for staff breaks. Start with the area that loses the most seats to cold, add one heater, and watch how guests respond for a week before buying the rest. A phased rollout lets you correct placement mistakes before they are repeated across the whole patio.

Common Mistakes

1. Buying before checking fire code, then being told the heaters cannot be used under the awning.
2. Placing towers too close to umbrellas, planters, or wood railings.
3. Underestimating wind, which can cut effective coverage by half.
4. Storing spare propane cylinders indoors or in unventilated spaces.
5. Skipping staff training on lighting, shutting down, and moving heaters safely.

One more operational note: keep a written shutdown checklist at the host stand. Close the tank valve, let the burner cool, cover the head, and chain or lock portable units overnight so they cannot be moved by passersby. Guests also notice a heater that is clearly cared for, with clean glass and a tidy base, and that small detail supports the impression of a well-run patio.
