Best OverallA compact, proven radiant heater for camping and small outdoor spaces, and it pairs well with the 20 lb tank hose kit for runs longer than a couple of hours.
A well-reviewed propane heater that multiple owners credit with getting them through extended power outages and deep cold, with only scattered complaints about build feel.
A rugged, adjustable propane forced air heater built for warming large work spaces fast, not for indoor residential rooms.
A tank top propane heater that screws onto a 20-100 lb cylinder and puts out 10,000 to 45,000 BTU per hour, suited to garages, job sites and campsites needing high-output portable heat.
A straightforward manual propane heater for a small room, without the thermostat that Mr. Heater's larger radiant models offer.
A high-output, electricity-free convection heater built for large open spaces, worth it if you have a 100 lb tank and a big area to heat rather than a room.
A practical two-pack for anyone who needs portable propane heat in more than one spot at once, such as a tent and a blind, or simply a spare on hand.
A fixed vent-free wall heater with real safety redundancy and thermostat control, worth it mainly if you are set up for professional installation and want set-and-forget room heat rather than a portable unit.
A straightforward vent-free convection heater for a room up to 250 square feet, though it is not suited to higher elevations given the manufacturer's own altitude warning.
A vent free wall heater that runs on propane or natural gas and warms people and objects with radiant tiles. Floor feet are not in the box, so plan on wall mounting unless you buy them.
A portable propane heater sold as a pair, with radiant and forced air output for living rooms, garages and workshops. Indoor use depends on proper ventilation, and the listing does not say what fuel hardware is in the box.
A camo version of the standard Buddy heater aimed squarely at hunters who want heat without a bright orange or black housing giving away their position.
A high-output portable propane heater for construction sites, shops and large garages, with hose, regulator and overheat shutoff included. The propane tank is sold separately and power details are missing from the listing.
Popular PickA straightforward ventless propane heater for small to mid sized rooms, with the safety sensor and thermostat control that matters most in an indoor fuel burning unit.
A high-output ventless propane heater built for large spaces, with manual control that keeps the price down compared to thermostat models.
A ventless infrared propane heater aimed at spot heating rather than whole room warmth, with the same thermostat and safety sensor as ProCom's blue flame model.
A direct vent propane furnace that modulates its output to hold an even room temperature quietly. It needs a vent and gas line run by an installer, and some listed figures look garbled, so confirm specs with Rinnai.
A jobsite and camping propane heater with a fan, work light and device charging built in. Cordless use needs a DEWALT battery that is not included, and the listed weight is clearly wrong.
A fixed propane unit heater with quiet operation and a low profile for spaces that have gas piping and a vent route. It needs a gas line, a power supply and a flue, so plan the installation before buying.
A thermostat-controlled propane heater that mounts on a wall or stands on legs, with a blower to push radiant warmth into the room. The listing gives no heating area, so sizing it to a room is guesswork.

A listing appears only when it has a recorded price, a minimum customer rating, and enough ratings or monthly sales. Generic and unbranded listings are left out, while every real brand stays, including brands sold only on Amazon. The ones that pass are ordered by the ProductDome score, which weighs owner satisfaction, rating volume, demand and data quality.
Propane space heaters come in radiant designs that direct warmth toward people and objects, and convection designs that warm circulating room air. Indoor use must be explicitly permitted by the manual; an outdoor or construction heater is not a substitute for an indoor heater, and indoor models may require venting or specified ventilation. Once that requirement is met, decide whether you need warmth at a particular seat or work area, or heat spread through a room. Natural Gas Space Heaters use a different fuel supply, so a similar appearance or matching connector does not make one suitable for propane.
Size the heat output around that heating task and the space involved. Among the 5 products that list heat output, most fall between 13,400 and 36,600 btu, and 20,000 btu is typical.. For room heating, compare the manufacturer's sizing guidance with your room dimensions, insulation and exposure to drafts; advertised coverage depends on conditions that may differ from yours. For warmth at a work position, look for guidance on effective heating distance and direction, since a room coverage claim says little about how warmth reaches that spot. If your needs vary between mild and cold weather, compare minimum and maximum output: a high maximum can be less useful when the lowest setting still delivers too much heat.
A thermostat matters when you want the heater to maintain room temperature through changing conditions; manual heat settings require you to adjust output yourself. Look at how the thermostat operates, since some controls cycle the burner while others vary its output. Electricity requirements also separate otherwise similar heaters: distinguish power needed for ignition from power needed continuously for a fan or other functions, particularly if outage heating is your purpose. For a fan-equipped model used near conversation or television, look for operating-noise information and whether heating is permitted with the fan switched off.
Before buying, compare the manual's combustible clearances and any required flue route with the intended installation. Wall Mount and Floor Mount labels leave the approved arrangement unclear, so verify the mounting instructions and whether brackets or feet are supplied. Confirm the required propane supply pressure, permitted cylinder location, and whether the correct regulator and hose are included or sold separately. Follow the manual's ventilation and carbon monoxide alarm requirements; an oxygen-depletion shutoff does not replace an alarm. For upkeep, establish how the burner and air inlets must be cleaned and whether servicing requires a qualified technician.
