Start with the seating plan, not the BTU

Draw the chairs first. A dining table with six chairs in a circle wants a mushroom reflector above the middle, because its heat falls in a circle. A lounge set facing one direction wants an infrared bar aimed at the seats, because its heat travels in a beam. A party with guests standing and moving wants a pyramid column as a warm landmark, because people gather around a flame. BTU only matters once the shape matches the seating, and a well-shaped 11,000 BTU tabletop beats a mis-shaped 50,000 BTU mushroom for the table it serves.

Read coverage claims like a translator

Makers quote diameter, listings quote square footage, and neither is measured in wind. Convert diameter to a circle in your head: an 18 ft diameter circle has a radius of 9 ft, and comfortable warmth usually ends a step or two inside the claimed edge. Square footage figures hide the same edge effect behind a precise-looking number. For infrared bars, ignore circles entirely and think in rectangles: the beam footprint in front of the bar, at the mounting height the maker specifies.

Fuel is a subscription, electricity is an installation

Propane costs recur with every tank, and the tank routine, exchange, storage, lifting and swapping, is the real ownership chore. Electric heat costs recur on the bill instead, with no tank chore, but the Bromic bar needs a 230 to 240V circuit and the DR-338 needs only an ordinary outlet. Compare the two honestly: propane is cheap to start and chore-heavy to run, fixed electric is expensive to install and chore-free to run, and movable electric splits the difference with a lower output.

Clearances rule out heaters before price does

Measure overhead height before falling for a pyramid: 89 to 91 in of column plus the clearance makers require above it rules out low pergolas and many covered patios. Measure sideways clearance too, since propane manuals ask for feet of clear space around the heater and above it, and a heater squeezed against a fence or a curtain is a hazard, not a bargain. Electric bars have their own clearances, including an 8 ft mounting height for ceiling mounting on the Bromic, which rules out low ceilings just as firmly.

Wind is the specification nobody prints

Every propane heater in this category is rated for wind below about 10 mph, and makers warn that efficiency drops below about 40 degrees Fahrenheit. A patio that funnels wind between buildings will defeat any propane shape, and the answer there is either a windbreak, a sheltered corner or an infrared bar that heats people rather than air. If wind is permanent, do not buy a taller pyramid hoping height helps: height catches more wind, not less.

Ignition, covers and storage decide year two

Year one is about heat, year two is about whether the heater still lights. Electronic and pulse igniters fail first after storage, usually from a dead battery, a dirty burner or a corroded connection, all of which a cover prevents. Buy the cover if one is not included, store the heater upright and covered, remove the tank for long storage, and test the igniter before the first party of the season, not during it. A heater that lights reliably in year three was stored well in years one and two.

Questions, answered

Propane or electric patio heater: which is better?

Neither is better in general. Propane gives high output and portability with no electrical work, at the cost of tanks, wind sensitivity and clearances. Electric infrared gives instant, wind-proof, directional heat with no flame, at the cost of installation for fixed bars or low output for movable 120V models. Choose propane for open patios and large gatherings, electric for covered, windy or tank-hostile spaces, and the DR-338 tripod when the space cannot be modified at all.

How much patio space does a full-size heater need?

Count the base, the clearance and the circle. The base is about 32 in square for a mushroom and about 21 to 29 in square for a pyramid, clearances add feet on every side per the manual, and the warm circle needs chairs inside it, not on its edge. A full-size heater realistically wants a patio of at least 10 ft by 10 ft with clear overhead space. Smaller spaces belong to the tabletop or a wall-mounted electric bar, which take no floor at all.

Do patio heaters work in cold weather?

They work, but with reduced effect as the temperature falls and the wind rises, and several manuals note reduced efficiency below about 40 degrees Fahrenheit. Propane pressure also drops in cold tanks, which can weaken the flame. For genuinely cold evenings, seat guests closer, use a windbreak, and consider an infrared bar, which does not depend on warming cold air before it warms people.

What maintenance does a patio heater need?

Little, but regular: brush the burner, wipe the reflector, check hoses and regulators for cracks or leaks, keep the igniter battery fresh, and cover the heater when cool and not in use. Check the tank connection with soapy water when a new tank is fitted, looking for bubbles that indicate a leak. Annual attention before the heating season prevents most mid-party failures, which are almost always ignition, fuel or hose problems rather than burner failures.
