Best Portable Heaters (2026): Propane & Electric Compared

1. Mr. Heater Buddy (MH9BX) -- 4,000-9,000 BTU

$112

The Mr. Heater Buddy is the gold standard for portable propane heating and has been for over a decade. Its combination of indoor-rated safety features, simple 1 lb canister operation, and adjustable heat output (4,000-9,000 BTU) makes it the go-to choice for campers, ice fishers, and emergency preppers alike. The radiant heat design warms spaces up to 225 sq ft quickly, and the piezo ignition means no batteries or matches needed.

The built-in ODS (Oxygen Depletion Sensor) automatically shuts the unit off if oxygen levels drop too low, and the tip-over safety switch adds another layer of protection. At just 9 lbs and with a fold-down handle, it slides easily into a camping pack or truck bed.

2. DeWalt DXH12B -- 6,000-12,000 BTU

$165

The DeWalt DXH12B is a forced-air propane heater designed for job sites, workshops, and garages where you need warm air circulated quickly across a larger area. Unlike radiant heaters that warm objects in their line of sight, the DXH12B uses a built-in fan to push heated air throughout spaces up to 300 sq ft. It connects to either a 1 lb disposable canister or a 20 lb bulk tank with the included hose and regulator.

With variable output from 6,000 to 12,000 BTU, it heats a two-car garage noticeably within 15-20 minutes. The Quiet Burner Technology keeps noise manageable for a forced-air unit. Note: the fan requires 4 D-cell batteries, so it works during power outages without needing a generator.

3. Sengoku HeatMate (OR-77) -- 10,000 BTU

$185

The Sengoku HeatMate is a kerosene radiant heater that shines in extended off-grid scenarios. Where propane heaters burn through small canisters in 3-6 hours, the HeatMate's 1.2-gallon kerosene tank delivers a remarkable 14-16 hours of continuous heat at 10,000 BTU. That makes it ideal for cabins without electricity, long power outages, or any situation where refueling every few hours is impractical.

The radiant design heats objects and people directly rather than warming the air, so it feels effective even in drafty spaces. An automatic shutoff engages if the unit is tipped or bumped. The trade-off is the typical kerosene odor during startup and shutdown, and you must store kerosene fuel separately.

4. Lasko 755320 Ceramic Tower -- 1,500W (5,118 BTU)

$60

The Lasko 755320 is the bestselling electric space heater in America for good reason. Its slim ceramic tower design packs 1,500 watts of heating power into a unit that barely takes up a square foot of floor space. The built-in thermostat and two heat settings let you dial in comfort while the auto-eco mode cycles the heater on and off to maintain your target temperature -- reducing electricity costs compared to units that run full-blast continuously.

With a widespread oscillation feature, cool-touch exterior, overheat protection, and a self-regulating ceramic element, the 755320 is one of the safest electric heaters you can leave running in a bedroom or office. The remote control is a nice bonus for bedside use. The only downside: it requires a wall outlet, so it's useless during a power outage unless paired with a generator or power station.

5. Dr. Infrared DR-218 -- 1,500W (5,118 BTU)

$95

The Dr. Infrared DR-218 is purpose-built for garages, workshops, and semi-outdoor spaces. Unlike ceramic heaters that warm the air, the DR-218 uses infrared technology to directly heat objects and people in its path -- similar to how sunlight warms you on a cold day. This makes it highly effective in drafty, open-door environments where conventional heaters struggle.

The wall/ceiling mount design keeps it off the floor and out of the way, and the industrial-grade heating element is built to withstand dust, vibration, and temperature swings. At 1,500W on a standard 120V outlet, it stays within household circuit limits. For larger garage spaces, some users pair two units on separate circuits.

6. Campy Gear Chubby 2-in-1 -- 9,000 BTU

$70

The Campy Gear Chubby is a clever 2-in-1 device that functions as both a portable propane heater and a camping stove. At just 3.3 lbs, it is the lightest heater in this roundup by a wide margin, making it a favorite among backpackers, tailgaters, and car campers who want heat without hauling a heavy unit. The flip-top design converts from heater mode (radiant ceramic burner) to stove mode (open flame for cooking) in seconds.

At 9,000 BTU, the Chubby punches well above its weight class for raw heat output. The built-in tip-over protection and pressure-sensitive fuel cutoff add essential safety features. The downside is a shorter 3-4 hour runtime per 1 lb canister and no ODS sensor, so it should be used with ventilation and a separate CO detector when in enclosed spaces.

Carbon monoxide (CO) is an odorless, colorless gas produced whenever fuel is burned. Every year, accidental CO poisoning from portable heaters and generators kills hundreds of people in the United States. Following these rules can save your life:

BTU (British Thermal Unit) measures heating output. The general rule for moderately insulated spaces is 20 BTU per square foot. Poorly insulated garages, basements, or spaces with high ceilings need 25-30 BTU/sq ft. Here is a quick reference:

Electric conversion: 1 watt = 3.41 BTU/hr. A 1,500W electric heater produces approximately 5,118 BTU/hr, which comfortably heats a well-insulated 250 sq ft room.
