To extend outdoor dining into winter, add reliable heat (overhead or tabletop heaters), block wind with screens or an enclosure, and offer blankets and warm menu items. Then check the math: a heated patio only pays if the added covers cover the heater fuel, labor, and equipment. For most restaurants, a few well-heated tables beat a large cold patio.
Before you buy anything, confirm local rules. Fire codes, propane limits, permit requirements, and enclosure definitions vary by city, and your insurer may have its own conditions. Call your fire marshal and insurance agent first, and see how to set up outdoor dining at your restaurant for the permit basics.
Choose your heat source
| Option | Typical cost | Pros | Cons |
|---|---|---|---|
| Propane patio heater | Moderate upfront, ongoing fuel | Portable, strong heat | Fuel runs, clearance rules, tipping risk |
| Natural gas overhead heater | Higher install | Steady, no tank swaps | Permit and installation |
| Electric infrared heater | Moderate, power draw | No fuel handling, quiet | Needs electrical capacity |
| Fire pit table | Higher upfront | Atmosphere draws guests | Space, smoke, strict rules |
A rough rule is that one standard propane heater warms a radius of about 6 to 8 feet in calm air, so plan one per two or three tables and place them with the required clearances. Wind cuts that sharply, which is why windbreaks matter as much as heaters.
Control wind and cold
Clear or heavy-duty panel screens, planters, and fabric sides stop wind without a full enclosure. Add a door flap or double entry so staff do not let cold air in on every trip. Blankets on chair backs cost little and guests love them; budget for laundering. Put the coldest tables, usually the far corners, at the bottom of your seating priority.
Do the break-even math
Heat costs money every hour it runs. A propane heater might burn about a gallon or so of fuel per hour on high, so fuel can run a couple of dollars an hour per heater, plus tank swaps and labor to light and check them. Compare that with the extra sales you earn.
Example for a patio with 8 heated tables and 3 heaters:
| Item | Per night |
|---|---|
| Extra covers: 8 tables × 1.2 turns × 3 guests × $32 | $921.60 |
| Food and beverage cost at 31% | -$285.70 |
| Heater fuel: 3 × 5 hrs × $2.50 | -$37.50 |
| Extra server labor | -$60 |
| Net added profit per night | $538.40 |
That example assumes a good night. Run the same sheet with a slow-night number, because cold weather swings demand. The free calculator lets you enter your own turns, check, and costs. Use your actual margins from how to calculate food cost percentage.
Adjust the menu and service
Guests outside in winter want warm food and drinks. Add hot cocktails, cider, soup, and braises. Keep the menu shorter so food leaves the kitchen quickly and arrives warm. Our guide to how to introduce a seasonal menu covers timing, and beverage menu strategy for higher checks shows how to price warm drinks.
Service also changes. Run covered food-runner trays, use a hot plate warmer at the pass, and assign a server to check on heaters and blankets. Reservations help here: take them for the patio so you do not leave guests waiting in the cold, and read managing reservations and no-shows.
Safety checklist
- Keep heaters the manufacturer-specified distance from walls, awnings, and guests.
- Store propane tanks outside and upright, never inside the building.
- Train every shift lead on the shut-off procedure.
- Check for carbon monoxide risk in any enclosed or tented space.
- Review restaurant safety and accident prevention and update your insurance.
Promote it
Tell people the patio is open and heated. Post photos of the glow and the blankets, add it to your Google profile, and mention it in your email list. See setting up Google Business Profile for restaurants and building an email list for your restaurant.
A winter patio is a numbers game. Heat a few tables well, block the wind, and run the break-even math on a slow night before you buy more heaters.
Track what it earns
Tag patio tables separately so you can see their sales and labor. Cobblestone POS is a free, all-in-one POS with reporting and table management built in, so you can see whether the patio earns its keep without paying a monthly fee. Compared with systems costing around $470 a month, that is more cash for heaters and blankets.
