: Propane "Torpedo" Heater Question

11-26-2010, 02:24 AM
I'm interested in putting a portable heater in my garage and i'm leaning toward a propane "torpedo" heater. It seems to be the most cost efficient route.

I plan on getting a heater similar to this: http://www.lowes.com/pd_154996-88644-RMC-FA60L_0__?productId=3255484&Ntt=propane+heater&pl=1&currentURL=%2Fpl__0__s%3FNtt%3Dpropane%2Bheater It's more than enough BTU for my size garage.

My question is this, can you use a 20LB cylinder with these heaters. I've done some searching and have heard that you do have to use a 100LB cylinder...then again I've also heard you do not. :shrug

i got an OLD torpedo heater. i use the same propane tank that a grill uses. get about 10 hours of use on it if i shut it on and off. DO have GOOD ventilation. maybe it's because mine is old but it WILL fawk your head up pretty quick.

but damn it heats shit up good.

X2 on the ventilation. There have been a couple of times that I forgot to crack the garage door and found myself light headed wandering around the garage. The one I had ran off the same tank I used for my grill, and when it was full I could get about 10 - 15 hours out of it.

Another one to consider would be a kerosene Reddi-Heater. Same concept, except you fill it with kerosene -- no propane tank to hook up.

I've used a kerosene forced-air heater in my shop for years. Sure, you have to crack the door to let the fumes out, but the amount of heat they put out more than compensates for that.

EDIT: Just noticed the heater you're considering is $99...the cheapest kerosene heater is $299...huge price difference.

kerosene is expensive!

Well, if you can handle a little black smoke, you can run diesel through it...done that a time or two, in a pinch.

for as little as i use it, i'm happy with leaving a tank of propane hooked up to it.

We had a kerosene heater in the garage for a while, but it seemed that the propane heater worked alot better.

Thanks guys. I just wanted to be sure I can run it with the tank from my grill before I went out and bought one.

FWIW, I spent 18 years in propane and natural gas.Hank Hill ain't got shit on me. For "mileage" comparisons,LP has 93,180 btu's per gallon. Weight is 4.24 lbs/gallon.Grill cylinders are filled to 80% liquid capacity,resulting in about 4.7 gallons per tank. Blue Rhino stops at 4.5 for "safety margins",and it also doesn't hurt "profit margins".
That heater you're looking at should work well for your needs. Stay clear of anything running on Coleman campstove cylinders.$$$

I've had one of these,http://www.mrheater.com/images/products/fam_MH42Medsize.jpg,for my shop forever.It's a little slower than what you're looking at,but has 3 settings(1,2,3 burners),and during a power outage(or campout) you can remove it from the cylinder collar,lay it on it's back and make Mac&Cheese.
Back in '03,Isabel knocked my power out for 5 1/2 days.I lol'd.

EDIT;I feel I should have a disclaimer here,but the heater I have is 99% efficient.The reason it's outdoor rated is because the cylinder itself is not approved for indoor use.
Years ago,a customer had this cool little rollaround infrared cabinet heater with a 20# cylinder in the back.By the time I went looking for one they had been jerked off the shelves because of the cylinder.

Get a thermostat, once I added one to mine it was so much better. less thatn $100 but well worth it.

IDK how expensive they are, but you could get a waste oil burner setup used maybe...and just run it off old oil. :shrug:

Just accept waste oil for free...put a sign up lol.

IDK otherwise, i agree kero is $$$ after a while...but it does work. :thumbup:

You might even consider a large oil Radiator heater. I had one in a drafty home I rented for awhile and placed a small fan blowing across the fins at and angle set on low and the radiator set on high. It would definitely keep me toasty in 30* temps. It took awhile to get really warm but once there it kept it there. Used electricity and you didn't have to worry about ventilation.

wood stove

X2. I wish I had a wood stove in the garage. I've thought about before, but never really looked into it. Running the chimney would be the hard part.

I had a party at my house in highschool and I had one of these set up. It was alot bigger than that one though. This chick was standing infront of it staying warm and bent over to do something and her hair caught on fire. Just be careful.

The propane tank always looses pressure in mine and then the flame gets weak I prefer kerosene it isn't affected by temperature like propane. I made a 20' cord up with one of those 120v thermostats and a 2x4 rectangle box with a couple cord adapters I set the thing at whatever temp I want and it works great no duct tape required.

both my brother and brother in-law have one, they're really quite simple to put in. my brother heats his home with it all winter, and it keeps the house HOT. my bro in-law has his in the garage it works great as well.

Get a multi-fuel heater like this one- http://www.northerntool.com/shop/tools/product_200443885_200443885 and you can run diesel through it. Much cheaper than kerosene.

That heater is gonna throw one hell of a jet flame out of the front of it-how big is your garage?

that's my favorite part about my torpedo heater. turning the lights off in the garage and looking at the mini-flamethrower. :toothless
