Best Propane Torpedo Heater for a Garage
As an Amazon Associate we earn from qualifying purchases. Details
A propane torpedo heater for a garage is judged on three listed figures: the heat output in BTU, the area the seller says it covers, and the hose and tank it needs. Only three of the six listings below describe a torpedo form. The rest are pedestal or portable forced-air heaters that the listings also place in garages. Listing figures were checked on 11 October 2026 and are shown as the sellers state them.
Quick answer: if you want a torpedo shape, the InoKraft (68,000 BTU, 30,000 to 68,000 BTU variable) and the NORTHSKY (85,000 BTU) list a torpedo form in their specifications, and the Anrain title does too. If you need the most listed output, the Anrain lists 150,000 BTU, and the Mr. Heater and GASLAND each list 125,000 BTU.

How we chose these six
We kept the listings that name a propane, forced-air heater and state a BTU figure. Every product is sold on Amazon, so the criteria come from the listing data alone. We did not test any heater, and nothing below reports how a heater performs in a real garage.
- Fuel and form: the listing says propane, and the form is either torpedo or pedestal as the specifications state.
- Output: the listing gives a BTU figure that can be compared with the others.
- Listing warnings: we relay the safety text the seller gives, and we do not add to it.
1. InoKraft MAXHEAT MH68, 68,000 BTU
The InoKraft is listed as a 68,000 BTU forced-air propane heater in a torpedo form. The bullets state a variable output of 30,000 to 68,000 BTU, and say it heats an area up to 1,600 sq ft, which the listing describes as suited to 1 to 6 car garages. The listing says the fan raises the temperature in 10 minutes, and it includes a 10 ft hose. The seller notes that a 20 lb propane tank or larger is needed. The specifications give dimensions of 17.51 by 16.53 by 10.8 inches. The bullets list overheat auto-shutoff and a 1-year warranty, and say the area must be well ventilated.

2. Mr. Heater 125,000 BTU
The Mr. Heater is a 125,000 BTU forced-air propane heater in a pedestal form, weighing 19.7 pounds and measuring 9 by 25.25 by 17 inches. The listing says it heats up to 3,125 sq ft and includes a 10 ft hose and regulator. The bullets describe a quiet burner and recommend it for well-ventilated construction sites, barns, warehouses and workshops. The specifications list the room type as garage and workshop but the usage as outdoor only, so the listing does not settle whether it is meant for indoor garage use.

3. Anrain 150,000 BTU Torpedo Heater
The Anrain is the largest listed output in this group at 150,000 BTU. Its title calls it a torpedo heater, but the specifications list the form as pedestal and the mounting as torpedo, so the listing is not consistent on the shape. The bullets give a range of 120,000 to 150,000 BTU/h across low, medium and high settings, and a coverage of 4,305 sq ft. The heater comes with an 11 ft hose and regulator, and the seller says a 20 lb tank is sold separately. The listing says it has swivel casters with brakes and an adjustable height.
The safety text in this listing is the most detailed of the six. It says the unit must not be used on wooden floors or near flammable materials, and that it must not be used in unventilated spaces. It also says carbon monoxide is produced, and that the user should stop and not resume if a gas odour is noticed.

4. NORTHSKY 85,000 BTU Portable Torpedo Heater
The NORTHSKY is an 85,000 BTU propane heater in a torpedo form with an adjustable tilt head. It weighs 12 pounds, and the specifications give dimensions of 10.83 by 21.26 by 14.17 inches. The listing includes a 10 ft propane hose and regulator. The listing does not give a coverage area, so this is the only one of the six where you cannot compare the room size. The specifications list the room type as patio, while the title and bullets mention garages and jobsites. The minimum temperature setting is given as 40 °F.

5. Remington LP Forced Air Heater, 60,000 BTU
The Remington is a 60,000 BTU forced-air propane heater in a pedestal form, weighing 11 pounds according to the bullets. The listing says it heats up to 1,500 sq ft and is suited to construction sites, workshops, garages and barns. It uses electronic ignition and runs on a 120 volt supply, and it includes a 10-foot LP cylinder hose and regulator. The tank is not included, and the listing says it runs on a 20 pound propane tank. The safety features are listed as a thermocouple, a high-temperature limit shut-off and a flame-out fuel cut. The heat output field in the specifications reads as a malformed unit, so the 60,000 BTU figure is taken from the bullet.

6. GASLAND 125,000 BTU Propane Heater
The GASLAND is a portable forced-air propane heater with an adjustable output of 75,000 to 125,000 BTU. The bullets say it covers up to 3,100 sq ft, and that it comes with a 10 ft propane hose and regulator. The listing says that, with a standard 20 lb tank, it gives about 5 hours of run time on the low setting. It runs on 115 volts and has continuous electronic ignition. The bullets say it is CSA certified and has an overheat detection system. The specifications list the form as portable and the minimum temperature setting as 40 °F, and the bullets give a 1-year warranty against manufacturing defects.

Worked example: how long a 20 lb tank runs in a garage
Take the GASLAND listing. It states about 5 hours of run time on the low setting with a standard 20 lb tank. If you run the heater for 2 hours each evening, one tank covers about 2.5 evenings (5 divided by 2) on low. The listing does not give run time for the high setting, so do not assume the same figure at 125,000 BTU.
For room size, take a garage of 20 ft by 20 ft, which is 400 sq ft. The Remington lists coverage of 1,500 sq ft, so it has room to spare on paper, while the Mr. Heater lists 3,125 sq ft. These coverage figures are seller claims, and the sellers do not use one common method, so treat them as a rough guide only.
What the listings do not say
None of the listings gives an independent test of how fast a heater warms a garage, and the 10 minute warm-up in the InoKraft bullets is the seller’s claim. The listings give different BTU figures in different places, as shown above, and the Anrain title and specifications disagree on the form. The listing data is dated 11 October 2026. Check the local rules for indoor fuel-burning heaters before you buy.
Frequently asked questions
Can a propane torpedo heater be used in a garage?
Several listings say they are made for garages, including the InoKraft, Mr. Heater and Remington. The Anrain and GASLAND listings also say they are for indoor use, but the Mr. Heater specifications say outdoor usage only. Read the listing’s safety text and ventilation notes before you use one indoors.
How many BTU does a garage heater need?
The listings do not give a formula. Compare the coverage figures with your garage size, and remember that the sellers do not use one common method. A 400 sq ft garage sits well within the Remington 1,500 sq ft coverage claim.
Do these heaters come with a hose and regulator?
Most of the listings include a 10 ft hose and regulator. The Anrain lists an 11 ft hose. The Remington lists a 10-foot hose but says the tank is not included, and the Anrain says a 20 lb tank is sold separately.
How long does a 20 lb propane tank last?
Only the GASLAND listing gives a run time, which is about 5 hours on the low setting with a standard 20 lb tank. The listings do not give run times for the high setting.
Are these heaters safe to leave running?
The listings describe overheat shut-off, flame-out cut-off and thermocouple safety features, but they do not state that the heaters can be left unattended. The Anrain listing warns against unventilated spaces and carbon monoxide, so follow the listing’s warnings.
Conclusion
For a garage, the Anrain and GASLAND listings give the largest listed outputs, and the InoKraft and NORTHSKY are the two torpedo-form listings. The Remington is the simplest pedestal choice at 60,000 BTU. Check the ventilation and the form figure before you order.
