Fall is when a good patio earns its keep — crisp evenings, low sun, no bugs to speak of. The problem is that the party usually moves inside about an hour after sunset, not because anyone wants to leave, but because fingers go numb. A patio heater fixes that math. The right one buys you six to eight extra weeks of outdoor evenings on each end of the season.
But patio heaters are not all the same tool. A 48,000 BTU mushroom heater and an 11,000 BTU tabletop unit solve different problems, and buying the wrong one is how people end up huddled around a heater that feels great on one side and useless two chairs over. Here’s how to choose, and the three models we’d shortlist for most backyards.
Quick Picks

| Best for Small Patios | Cuisinart Portable Tabletop Patio Heater (COH-500) | 11,000 BTU | Tables, balconies, and small seating areas |
How to Choose a Patio Heater
BTU output is a coverage claim, not a comfort guarantee
BTUs tell you how much heat the burner produces, not how warm you’ll feel. Radiant heat fades fast with distance — at 9 feet from a standard mushroom heater you feel a fraction of what you feel at 4 feet. As a rule of thumb, a 46,000–48,000 BTU freestanding heater comfortably warms a circle about 10–18 feet across on a calm night, and noticeably less when the wind picks up. Wind is the silent killer of patio heat; a sheltered patio gets far more out of the same heater than an exposed deck.
Fuel: propane is the default for a reason
Propane mushroom heaters run on the same 20 lb tank as a gas grill, which most households already own. Expect roughly 8–10 hours on high from a full tank. Electric heaters are cheaper to run and can be used in some covered spaces where propane can’t, but corded 1,500W units produce far less heat. Natural gas makes sense only for a permanent installation. For most people reading this, propane is the answer.
Safety features that are non-negotiable
- Anti-tip shutoff — cuts the gas if the heater is knocked over. Do not buy a heater without it.
- Wheels — a 40 lb heater with a tank inside is not something you want to carry. Wheels make repositioning and storage realistic.
- A weighted or fillable base — sand or water ballast keeps a tall heater honest in a breeze.
Placement matters as much as the heater itself — clearances, surfaces, and storage are covered in our patio heater safety and placement guide.
The Best Patio Heaters for Fall
Best Overall: Hiland 48,000 BTU Propane Patio Heater
The Hiland HLDS01 series is the heater you see outside every restaurant patio in America, and that commercial pedigree is the point: it’s a proven design with replacement parts that actually exist. At 48,000 BTU it’s at the top of the residential output range, the reflector throws heat across a genuinely useful radius, and the access door in the base makes tank swaps painless. Finishes like hammered bronze look better than the industrial stainless most competitors ship.
Why it stands out:
- 48,000 BTU — the strongest output in this class
- Wheels and an adjustable table on many configurations
- CSA certified, with a real parts and service network behind it
Best Value: Amazon Basics 46,000 BTU Outdoor Patio Heater
The Amazon Basics heater gives up very little to the Hiland — 46,000 BTU, piezo ignition, tip-over shutoff, wheels, and a fillable base reservoir — at a price that routinely undercuts name brands. The finish and hardware feel a step less premium, and in high winds the lighter base wants its ballast filled, but the heat-per-dollar math is hard to argue with. If the heater will live in the garage between weekends, this is the sensible buy.
Why it stands out:
- 46,000 BTU with a claimed 18-foot heat spread on calm nights
- One-year Amazon Basics warranty
- Multiple finishes, so it doesn’t have to look like restaurant equipment
Best for Small Patios: Cuisinart Portable Tabletop Patio Heater (COH-500)
Not every patio can fit an 87-inch tower, and not every gathering needs one. Cuisinart’s tabletop unit puts out 11,000 BTU — enough to warm the people actually sitting at the table, which is where the conversation is anyway. It runs on a 1 lb propane canister (about 2 hours) or a standard 20 lb tank with an adapter hose, weighs just 8.5 lbs, and includes the tilt switch and burner guard you’d want on something sitting at elbow height.
Why it stands out:
- Heats the table, not the whole yard — exactly what small spaces need
- Truly portable: tailgates, camping, and porches are all fair game
- Adjustable heat with a safety tilt switch

FAQ
How many BTUs do I need for my patio?
For a typical 4–6 person seating area, 46,000–48,000 BTU freestanding propane is the sweet spot. For a single table on a small patio or balcony, an 11,000 BTU tabletop unit is usually enough — and far easier to store.
Can I use a patio heater under a covered patio or pergola?
Only with the manufacturer’s stated clearances — freestanding propane heaters typically need several feet of clearance above and to the sides, and many covered structures don’t qualify. Check the manual for your model, and read our safety and placement guide before you light one under anything.
How long does a 20 lb propane tank last in a patio heater?
Roughly 8–10 hours on high for a 46,000–48,000 BTU heater, and considerably longer on lower settings. A spare tank is the cheapest insurance a fall party can buy.
