Our top 3 portable propane heaters right now
Three indoor-safe Mr. Heater Buddy models that come up again and again in owner reviews — one for most rooms, one for large spaces, one for maximum portability. See the full ranking →
Best for Garages, workshops, tents, ice shanties and small-to-mid rooms
- 4,000–9,000 BTU, low/high settings
- Built-in oxygen depletion sensor (ODS) and tip-over shutoff
- Runs on a 1 lb cylinder or a hose-connected 20 lb tank
Why buy it: It is the single most-reviewed portable propane heater on Amazon, and owners across garages, hunting blinds and campers report the same pattern: it lights first try, heats a small enclosed space fast, and the safety shutoffs work as advertised.
Best for Larger garages, big canvas tents, and job-site trailers
- 4,000–18,000 BTU across three settings
- Two 1 lb cylinders or hose-connect to a 20 lb tank
- Fan-assisted heat distribution and swivel-out regulator
Why buy it: Owners who outgrew a standard Buddy report the Big Buddy comfortably carries a two-car garage or a wall tent the smaller unit could not keep up with, without giving up the indoor-safe sensor package.
Best for Ice fishing shanties, small tents, and single-room emergency backup heat
- 3,800 BTU fixed output
- Runs directly off a 1 lb disposable cylinder
- Sits under 10 inches tall — packs into a small bag
Why buy it: It is the cheapest way into the same indoor-safe Buddy platform; owner reviews agree that for a space under roughly 100 sq ft it will not be underpowered — the complaints start only when people try to heat something bigger.

One heater, very different jobs
The right propane heater changes more with the space than with the brand. Start from how you'll actually use it.
Hoses, regulators & CO detectors worth having
Most complaints that sound like a heater fault trace back to the tank, hose or a missing safety alarm. These are the extras owners reach for most. All tanks, hoses & accessories →
