Best Patio Heaters for a Covered Porch (and Why Most Propane Towers Don't Fit)

A porch roof changes which heaters you can safely use. Here are the best heaters for covered porches, from a plug-in infrared that mounts overhead to a tripod model for low ceilings, with the clearance numbers that decide it.

A porch roof is great for keeping you dry and terrible for most patio heaters. The classic propane “mushroom” tower stands about 7 feet tall and blows its heat and exhaust straight up. Many of their manuals ask for 2 to 3 feet of open air above the top of the heater, and Bromic, which makes commercial patio heaters, recommends at least 3 feet between a gas heater and the ceiling. Add those up and you need a ceiling around 10 feet high. Most porch ceilings are 8 or 9 feet.

So on a covered porch, the real choice is usually between an electric infrared heater, mounted overhead or on a stand, and a small indoor-rated propane heater. These four picks cover both. All four are in stock on Amazon this week.

Mounting heights and clearances come from each heater's own manual. Always follow the manual for your unit and your local code.

How we chose these

We haven’t tested these heaters on our own porch. Because a porch roof makes clearance the deciding factor, we started with the manuals: minimum mounting heights, distances from ceilings and walls, and what each maker says about outdoor and enclosed use. Then we checked each heater’s specs against the maker’s site and confirmed it was in stock on Amazon. Dr. Infrared’s carbon heaters come up again and again in covered-patio roundups, and their manuals are clear about where they can go, so they make up most of this list. We left out propane towers entirely, because few covered porches are tall enough for them.

What we looked for:

• A mounting rule your porch can actually meet. If the manual says 94.5 inches to the bottom of the heater and your ceiling is 8 feet, an overhead mount won’t work.
• Radiant heat. Infrared warms people and surfaces directly, which is what you want on a porch where warm air simply drifts away.
• Weather resistance. A porch roof keeps rain off, but blowing rain and humidity still reach the heater.
• Fuel that fits. Plug-in heaters are the simplest. Propane is for porches with no outlet.

1. Dr Infrared Heater DR-238 1500W Carbon Infrared Patio Heater: Best overall

Who it’s for: Porches with a reasonably high ceiling and an outdoor outlet nearby.

The DR-238 is a slim aluminum bar, about 35 inches long, with a carbon infrared element behind a guard. It plugs into a standard 120-volt outlet and has three heat levels, 900, 1200 and 1500 watts, which you change with the included remote. Carbon infrared heats up in seconds and gives off a soft orange glow rather than a harsh red one. There’s nothing to fill and nothing to burn, so there’s no smell and no exhaust under the porch roof.

The catch is height. Dr. Infrared’s manual says the lowest part of the heater has to sit at least 94.5 inches (about 7 feet 10 inches) off the ground, whether it’s on a wall or the ceiling. A wall mount also needs about 16 inches of space above the heater and 20 inches from the side walls. In practice, that means a ceiling mount needs a porch ceiling of roughly 8½ feet or more, and a wall mount needs closer to 10. Measure before you buy.

What bugs us: It’s a spot heater. A 1500-watt unit warms the people in a seating area under it, not an entire wraparound porch, and wind blows the warmth around on open sides. The manual also says to plug it straight into a wall outlet with no extension cord. Dr. Infrared recommends a weatherproof outdoor outlet.

Skip it if: your porch ceiling is 8 feet or lower. Get the tripod version instead.

2. Dr Infrared Heater DR-338 Patio Heater with Tripod: Best for low ceilings

Who it’s for: Standard 8-foot porches, renters and anyone who doesn’t want to drill into the porch ceiling.

The DR-338 uses the same 1500-watt carbon element and three heat settings as the DR-238, but it comes with a tripod stand that adjusts from about 3.6 to 5.9 feet. That lets you set it beside a seating area under a low porch roof and aim the heat at people instead of mounting it overhead. Dr. Infrared rates it IP55 for outdoor use. It has a tip-over switch on the stand that shuts the heater off if it gets knocked over. If you change your mind later, it also comes with a wall bracket.

What bugs us: A tripod takes up floor space and its legs are easy to trip over in the dark. Like the DR-238, it has to plug straight into an outlet, so you’ll need to set it within reach of the cord. Keep the front of the heater at least 3 feet from people, cushions and curtains.

Skip it if: your porch is busy with kids or pets running around. A mounted heater is out of the way.

3. Dr Infrared Heater DR-239 3000W Patio Heater: Best for large porches

Who it’s for: Big porches, outdoor kitchens and screened rooms with high ceilings, where a 1500-watt heater won’t cover the seating area.

The DR-239 doubles the output to 3000 watts, which Dr. Infrared rates at about 10,260 BTU. It’s IP55 weather rated, and it mounts on a wall or ceiling with the included brackets. A remote switches between two heat levels and standby. It’s about 41 inches long and weighs 7.6 pounds.

What bugs us: It runs on 240 volts, not a regular outlet. It has a NEMA 6-15 plug, and the manual calls for at least a 16-amp circuit, so most homes will need an electrician to add a 240-volt outdoor receptacle or hardwire it. The manual also requires a mounting height of at least 7.9 feet. Expect to pay around $350 for the heater before any electrical work.

Skip it if: your porch is a normal front porch with a couple of chairs. The DR-238 is plenty, and it plugs in.

4. Mr. Heater Big Buddy MH18B Portable Propane Heater: Best without an outlet

Who it’s for: Screened porches and three-season rooms with no outlet, and hunting camps or cabins where power is unreliable.

The Big Buddy is a radiant propane heater with three settings, 4,000, 9,000 and 18,000 BTU. Mr. Heater says it heats up to 450 square feet. It runs on two 1-pound propane cylinders, or a bigger tank with an extra hose and filter. Unlike a patio tower, it’s rated for indoor use. It has an oxygen depletion sensor that shuts it off if oxygen in the room drops, plus a tip-over shutoff. Because it sits on the floor, ceiling height doesn’t matter. The manual asks for 30 inches of clearance above it, 24 inches in front and 6 inches to each side.

What bugs us: It still burns propane, so it gives off carbon monoxide and moisture. On a closed-up porch, crack a window and keep a working CO alarm nearby. Mr. Heater has also dropped the built-in fan on some recent units, so check the listing if you want one. The heater works fine without it, but the fan pushes the warmth farther.

Skip it if: you have a porch outlet you can use. Electric infrared is simpler and produces no fumes.

Getting the most out of a porch heater

• Measure the ceiling first. Measure from the porch floor to the lowest beam or fan blade, not the highest point of the ceiling.
• Aim at people, not space. Infrared works like sunshine. Point it at the seats, slightly downward, rather than at the middle of the porch.
• Block the wind. One side curtain or outdoor shade on the windward side makes a bigger difference than more watts.
• Mind the circuit. A 1500-watt heater draws about 12.5 amps. On a 15-amp outdoor circuit, don’t plug anything else in at the same time.
• Keep the 3-foot rule. Every heater here wants about 3 feet of clear space in front, away from cushions, curtains and blankets.

Quick answers

Can you use a propane patio heater on a covered porch? Usually not a tall mushroom heater. Most need 2 to 3 feet of clearance above the top, which means a ceiling around 10 feet high. Check the clearance table in the manual for your heater.

Are infrared heaters safe under a porch roof? Yes, if you follow the manual’s mounting heights and clearances. They don’t burn anything, so they give off no fumes.

How much area does a 1500-watt patio heater warm? Think of it as one seating area, about the space where two to four chairs fit, not a whole porch. On a windy, open porch, expect less.

Can I plug an outdoor heater into an extension cord? Dr. Infrared’s manuals say not to. Plug it directly into a weatherproof outdoor outlet.
