Behind the kerosene garage heater, a pressure gauge is integrated to show the combustion pressure. 

The unit requires a 115Velectric connection by an extension cable to power up and consumes around 2.7 amps current and 450 watts during runtime.

Finally:  There are obviously some fantastic kerosene heaters on the market that are lower than 75K BTU and higher than 190K BTU. We haven’t included them, keeping in mind both POWER & EFFICIENCY. 

14 Essential Things About Kerosene Garage Heater

1. Are the Kerosene Garage Heaters Healthy?

If you use the best quality kerosene heater the right way with proper ventilation and clean oil, they won’t be unhealthy. 

Oil and Gas heaters, or wood-burning fireplaces, are remaining used as an indoor heating system for longer than a century. Even people used them before the invention of electricity!

Have you ever heard any ancient people feel sick sitting beside a fireplace? Most probably NO. Cause they used proper ventilation and clean fuels.

All these fuel (gas/oil) or wood-burning heating system produces heat by breaking Carbon Bonds inside their molecules. Surely you know, fire needs oxygen to be burned. So, the internal reactions create CO, CO2, NOx (x is a variable like 1,2,3), and several toxic nontoxic gasses. 

However, if you ensure proper ventilation, 3 cubic feet for each 100K BTU, keep around 1-square feet window open to entre environmental air. In that case, there’s nothing to be worried about.

You may install a toxic gas identifier or indoor air quality checker just beside your kerosene heater to remain worry-free for further safety. Feeling curious about “are kerosene heaters safe indoors?” Then I will request you to read my article to learn briefly.

2. The hourly cost of a Forced Air Kerosene Heater?

It depends upon BTU, ambient temperature, and the preset temperature of your heater. 

I’m providing an hourly fuel-consuming chart assuming that the heater will run for a whole hour. You may find the “hourly expense” multiplying the fuel price in your state.

  • 75K BTU Forced Air Kerosene Heater Consumes = 0.54 gal/hr
  • 80K BTU Consumes = 0.55 gal/hr
  • 125K BTU Consumes = 0.76 gal/hr
  • 135K BTU Consumes = 0.9 gal/hr
  • 175K BTU Consumes = 1.40 gal/hr
  • 180K BTU Consumes = 1.41 gal/hr
  • 190K BTU Consumes = 1.44 gal/hr

Note: All the forced air kerosene heater has a built-in electric thermostat. So it never will run continuously for hours. It will shut down, raise the room temperature, and restart again when required. So the hourly consumption will be lower.

Again, you may use diesel fuel or mix diesel with kerosene to reduce your fuel cost! 

3. Forced Air Kerosene Heater vs. Propane Heater- Which one is better for Garage?

Both are similarly powerful and workshop-friendly. To compare them hardly, here is an hourly expense calculation of each type of heater.

Forced Air Propane Heater 125K BTU

20 Ibs propane tank lasts for 3 Hours. 

20 Ibs = 20 ÷ 4.3 gallon = 4.65 gallon. (1 gal propene = 4.3 Ibs)

So, the hourly consumption is 4.65 ÷ 3 = 1.55 gal/hour.

Suppose, per gallon propene costs around $2.3

The hourly operational cost is 2.3X1.55 = $3.565

Forced Air Kerosene Heater 125K BTU

Hourly fuel consumption 0.76 gals. Suppose the fuel cost remains around $3.5/gal, then. 

The hourly operational cost will be $2.66

So, the Kerosene heater wins in terms of operational cost.

Let’s talk about Portability

125K BTU Propane Heater Weighs = 14.97 Pounds (Sunnydaze 125,000 BTU)

125K BTU Kerosene Heater Weighs = 59.2 Pounds (Mr. Heater MH125KTR)

So, including fuels, the kerosene heater will weigh near 100 pounds, so they have trailer wheels for portability. But they don’t have any extension like gas cylinder like propane heater.

So, in terms of portability, moving a kerosene heater is compact and easy. Finally, I should say, kerosene heater offers more advantages than propane heaters! Now the decision is yours obviously.

You may read my guide on propane vs kerosene forced air heaters to make sure which one suits you the best.

4. Reliable brands of Qualitiful Kerosene Garage Heaters?

Prestigious Brands = Better Reliability, Longevity & better after-sale services.

Here are some great reliable brands for kerosene garage heaters.

  1. Mr. Heater: This brand is operating their business since 1957, and I can assure you won’t find any single type of space heater which they don’t manufacture. Unlike other heating brands that build both water & space heaters, Mr. Heater is specialized in the space heater industry. So electric, gas, catalytic, fuel, all shorts of space heaters from Mr. Heater is obviously great in quality!
  2. Dyna-Glo: It’s another great brand from North America. They manufacture gas grills, charcoal grills, gas, and fuel-driven heaters and machinery like them. Their after-sale service is incredibly fantastic. The most impressive service is their app support!!!
  3. Dura-Heat: Dura heat is also a gigantic heating industry and so reliable. Mainly they do manufacture large-capacity heating systems, and their products are familiar for better durability!

Note:  Products from popular brands are expensive! But does it means all cheap products from new or growing up products are bad? Not at all. We have enlisted some affordable products from new brands that can defeat these familiar brands badly! (Example: REMINGTON, REM-80T )

5. Can you Use Fuel Oil in a Torpedo Kerosene Heater?

Of Course, you can! All kerosene heater supports these SIX fuels.

  1. K-1 kerosene, 
  2. #1 diesel
  3.  #2 diesel 
  4. JP8/Jet A fuel
  5. #1 fuel oil
  6. #2 fuel oil 

You may use any of them which you do find at the most affordable price. Even you can mix two of them like diesel+kerosene to work more efficiently and clean.

6. How Long do the kerosene heaters burn per refill?

It depends on BTU, Fuel Tank capacity, ambient temperature, and the preset temperature of your heater. If the heater remains in MAX temperature and runs non-stop (which is never gonna happen!), here is the list below.

  • 75K BTU in Max setup 6-gallon tank runs for 11 Hours
  • 80K BTU in Max setup 5-gallon tank runs for 10 Hours
  • 125K BTU in Max setup 8.5-gallon tank runs for 15 Hours
  • 135K BTU in Max setup 10-gallon tank runs for 11 Hours
  • 175K BTU in Max setup 14-gallon tank runs for 10 Hours
  • 180K BTU in Max setup 14-gallon tank runs for 9 Hours
  • 190K BTU in Max setup 13-gallon tank runs for 9 Hours

I’ve enlisted this according to the kerosene heaters on our list.

7. Are Torpedo Kerosene Heaters Safe to Use in a Garage?

Yes, they are safe, but like all other high-capacity garage heaters, you would require to handle them with care.

First of all, kerosene heaters have integrated safety features, like overheating, flameout, tip-over, enclosed exhaust, etc. But it would be best if you never remained unconscious turning on the kerosene heater.

Secondly, the toxic gas emission may be harmful to you in the long run. Hence, you require proper ventilation, and I would suggest installing an “air quality monitor” nearby your kerosene heater to ensure the ventilation is okay.

8. Can you Leave a Torpedo Kerosene Heater On All Night?

Forced air kerosene heaters are for workshop/garage, industrial or commercial areas, not for living rooms!

So, if you require to work overnight, you keep them turned ON for how long you need them! If your garage remains empty, you should not keep a burning heater inside it.

9. Do I need to Vent a Torpedo Kerosene Heaters?

Of Course, you need it! I would suggest you have a three cubic feet vent area for each 100K BTU.

10. Do the kerosene heaters give off fumes?

No, they don’t give off fumes during runtime. But during startup, you may notice some fumes.

11. Do Odors Come From Forced Air Kerosene Heater?

Not really. I only got some odors during startup. But if you use diesel, no odor will be noticed at all.

12. Few Drawbacks of Forced Air Heaters

The main Drawback is their Exhaust Sound!!! It sounds like a Jet Engine! 

Secondly, you have to handle them very carefully; the Exhaust pipe remains too hot!

13. Do they Need Wick? How do They Work?

No. They never will require any Wick.

Forced Air Kerosene Heaters work like combustion engines. A blower fan passes ambient air forcefully inside the combustion chamber, where the fuel sprayer nozzle mixes the fuel with the air. Then an electric spark ignitor sets a fire inside the combustion unit, and thus heat passes through the exhaust pipe.

14. CFM of Garage Heater – Explanation

CFM stands for cubic feet per minute. So, one kerosene heater has a 240 CFM score means that the heater can heat up 240 cubic feet every minute. 

Now the fact is, should you search for a CFM score before buying a kerosene heater? Not really. Staying concerned about BTU is more than enough to choose a perfect-sized unit for you!
