Temp Heat in Garage
Can't afford to put natural gas in my 26 x 30 garage yet, so looking for alternatives. Any recommendations for fairly economical and efficient propane heaters for limited use? Thanks!!

Re: Temp Heat in Garage
This probably won't help you but I heat my house and my shop (a separate building) with an outdoor wood boiler. The initial install and purchase cost was around $8k. The boiler has a 400,000 btu capacity. It's oversized for my 1800 square foot house and 1500 sq foot shop space I heat but I have the ability for expansion without replacing equipment. I also live in a rural area where smoke is not an issue and I have an abundant supply of wood. I keep my shop at 60 degrees all winter.

Re: Temp Heat in Garage
Rick - I use a propane tank with a heater https://www.homedepot.com/p/Dyna-Glo...60DG/203534107
I have it mounted to a small hand truck, and move it around to where I am working. Surprised at how well it heats and economically as well. I use the propane tank that is about twice as large as the one shown in the photo.

Re: Temp Heat in Garage
I bought a "Mr. Heater Big Max" from Northern Tool for my garage last year and like it. As I recall it was less than $500.00 for the heater the vent pipe was $160.00 or so locally. Mine is on Natural Gas but I THINK they can be converted.
What ever heater you decide on I'd recommend that you buy a vented unit as the by products of combustion of propane are H2O and CO2 which will put a lot of water vapor into your garage plus there is always the chance of CO/carbon monoxide with an unvented unit. |

Re: Temp Heat in Garage
I have a pellet stove in my 16 by 28 shop. Fully insulated. On days I won't be in the shop I start it in the morning and shut it off about 6 hours later. When I am working out there I leave it on until I am done. Plenty warm for working. Depends on the outside temperature. Right now it is 18 degrees (f) and very windy. The stove will struggle to keep it in the low 50''s. Running it 8 hours takes less than 1/2 bag ($5/bag)
I am very happy with it. John |

Re: Temp Heat in Garage
be careful with any flame heater to be safe it must be mounted high & vented.

Re: Temp Heat in Garage
I run a forced air furnace all winter long, it works very well and is not too bad on cost.
I keep it at 55 degrees unless I’m painting or something. You can get a vertical one that takes up little space and These units can be bought used for a reasonable price. |

Re: Temp Heat in Garage
I have an oversized propane heater that hangs from the ceiling. I keep the thermostat set at 45 deg. Turn it up when I working, take less that 15 min to be up to temp I want.

Re: Temp Heat in Garage
I used one of those jet kerosene heaters for years (until upgrading to a natural gas Hot Dawg). I was worried about CO2, but plugged in one of those CO2 detectors and it never went off...................
Of course what they said about anything flammable being close by is true. |

Re: Temp Heat in Garage
I have a ventless 35,000 BTU wall mounted propane heater in my shop, which is 30 X 40 with 14 ft ceilings and is insulated. I installed it because I wanted something cheap and easy to keep the chill off in the fall and spring. I am in north central Minnesota, but I usually winter in Florida, so I don't need anything very robust for the winter. This winter, courtesy of Hurricane Irma, I am stuck in Minnesota, so I have been using my heater almost daily. I am amazed at how well it works. I usually go to town in the morning to get the mail and stop by my shop (which is 3 miles from my home) on the way back and start the heater. I then return home, do whatever needs to be done, and go back up to my shop. By that time, the temperature is around 60 degrees, which is plenty comfortable if you're working. After it gets to 63 or so, it shuts itself off (it is thermostatically controlled) and cycles from then on. I have two 20 lb propane bottles connected together by a hose gizmo I got off Amazon. I go to the shop 5-or 6 days a week for 4 to 5 hours at a time. With this pattern of use, the 40 lbs of propane lasts about two weeks. The last two 20 pounders cost me $36.05 to fill. I also have a large ceiling fan that is on all the time, blowing downwards. All in all, I am extremely happy with this setup. I have had no problems with excess moisture or smells. I do have a quality carbon monoxide and gas detector installed. I highly recommend this kind of heater, especially to someone looking for something temporary. When you decide to go to something permanent, you will probably be able to sell a unit like this for almost what you paid for it.
There is one other factor that comes into play. My shop is in a storage complex and as such, is not free-standing. The unit on my right is not heated during the winter, but the one on my left is owned by a friend who keeps it at 45 degrees. I'm sure this makes heating my unit easier, how much I don't know, because the common walls are also insulated. Here is a link to the type of heater I have. I couldn't find my exact unit (which is 35,000 BTU and black), but this is close. BTW, these units can be switched from propane to natural gas with a turn of a valve with no extra parts needed. https://www.menards.com/main/heating...277994&ipos=19 |

Re: Temp Heat in Garage
Just watch it as most fire codes are pretty strict in regards to garages, gasoline and heat/flames. When I built my shop my insurance company wouldn't let me install any wood burning furnace or stove. You surly don't want to have your insurance company deny a claim for a totaled shop and car because of code violations.
In my shop I was able to install a high efficiency LP furnace just off the floor as it has a sealed combustion chamber and draws outside air for combustion. At the time, here in MN a regular furnace (or any source of flames) would have to be a minimum of 4' above the floor in a garage. |

Re: Temp Heat in Garage
I've often thought of making a solar panel for heating my garage (Lots of youtube videos are out there). How much heat they produce is impressive.But usually they only work when you don't need them.I'd like to build one anyway. Free heat.

Re: Temp Heat in Garage
I considered many options and ended up with an overhead heater, propane powered. Very happy with it. good insulation in walls and overhead help a lot to keep the operational costs down.

Re: Temp Heat in Garage
Strange that no one here has mentioned getting a heater from an old mobile home ? Does not require much room and should take the chill out of a shop. My basement is a constant 60 degrees and plenty warm for anytime I am down there.

Re: Temp Heat in Garage
In my old shop at the farm I had a vent less wall hanging propane heater which did a great job in my 36X30 with 8 foot ceiling room that I fabricated chassis in. I was skeptical about the vent less feature but used it 15 years with no problems. It just hung on the wall on one end of the shop. It was very economical. In my new 30X40 shop with 12 ft ceiling I have a hanging Hot Dawg vented overhead heater. I does a great job and burns very little propane.

Re: Temp Heat in Garage
My 32x40 shop is heated with a Hot Dawg and works great, but if I need something in my 3 car garage I use a jet propane heater. You can turn it on and point it in the direction where you need the heat to be.

Re: Temp Heat in Garage
I heat and cool my 26 x 36 garage with a mini split. I keep it at 50 during the week and bump it up to 60 or so on the weekends. Heat cost me about $3 a day.
In the summer I set it on the drying mode and it keeps it cool and dry or I can switch to full AC. Both the heat and AC are whisper quiet. I also have a 12KW ceiling hung electric heater for back up. I'm very pleased with the whole set up. |

Re: Temp Heat in Garage
Guys, some of you are getting waaaay of the subject, which was "Temp Heat". He's not looking for a furnace or wood stove; as a matter of fact, he specifically mentioned propane as his desired fuel. One of the nice things about some of these propane heaters is that they are fairly easy to sell when you are done with them. I sold a propane garage heater on Craig's List. Being careful, I wanted to make the exchange in a public place. The buyer suggested the parking lot at Home Depot, which is fairly centrally located. I thought it was kind of ironic, since I had bought it there a couple of years earlier for about $20 more than he paid. He did save sales tax, and it was properly broken in.

Re: Temp Heat in Garage
For those of you guys that are getting ready to pour floor in the shop or build a shop I highly recommend hot water in the floor of the shop I have an electric boiler which takes up no room as it is hung on the wall my shop will maintain Heat with no problem my thermostat is set on 65 and it stays that way the year round no maintenance no Flame and that warm floor is a greatest thing to work on there ever was. When I built the shop I spend my whole life working in shops with either heaters in the ceiling or the turbo diesel and propane heaters and freezing my feet off at all time again I would highly recommend the N for heat

Re: Temp Heat in Garage
Or was he looking for an alternate heat source, that would have limited use, that didn't require the high expense of the natural gas line?
Either way lots of good suggestions. |

Re: Temp Heat in Garage
I use one very similar to this. At full blast it will throw you out of the garage within a few minutes. I just used it in my 2 car very leaky garage on a 32 degree day pulling an engine out. Mine is a Coleman power mate , 80,000 to 2000,000 btu's and despite opening the doors three times in an hour it kept us warm. Bought it about ten years ago and has worked great ever since, although some years I didn't use it at all.

Re: Temp Heat in Garage
"Construction Heaters" (such as shown in Post #33 above) can be quite dangerous. I had one and I was working in my shop, about 4 feet from the heater with my back to it. I had blue jeans on and they had a small, frayed, hole in the back of my calf. All of a sudden, I felt extreme heat on the back if my leg, and found my pants were on fire. Frayed cotton is one of the most flammable materials there is (Boy Scouts use it with their "flint and steel" fire starters). The end result is that the back of my leg was badly burned and it took two months and a skin graft to recover. I never used that heater again and sold it shortly thereafter. Because of their very nature, these thing throw a tremendous amount of heat and can start anything close on fire. I wouldn't have one (obviously).

Re: Temp Heat in Garage
Are you looking to keep your hands warm or preserve your Ford? If it's the latter, you don't need heat, just control humidity. Dry atmosphere = dry and not rusty car. If it's the former, well the previous posts have all the information you need

Re: Temp Heat in Garage
This all Reminds me, many years ago in the Army, I was overseas and had purchased an old ex police Harley Davidson. Many foreign countries used Harley’s in the 50’s to 70’s.
It was winter and I didn’t want it in plain view in the motor pool while I worked on it. So I put it in the small boiler room behind the shop and started the restoration. It was very cramped, but nice and warm. |

Re: Temp Heat in Garage
I have used the jet type job heaters, big draw back is that they are very loud, kerosene really stinks, propane isn't that smelly but will get to you after 8 hours. Barrel stoves are cheap to set up and use if you have a good wood supply but on windy days you can get smoke fumes coming in. I have used one of those infrared overhead heaters but they must be used in a well insulated room to work good.

Re: Temp Heat in Garage
FYI: Another thing to consider. Burning one gallon of LP or nat gas produces almost 1 gallon of water vapor. If you are using a vent-less heater you are adding a lot of moisture into the building.

Re: Temp Heat in Garage
I really take exception to them being "dangerous'. If you were standing four feet from the unit there's no way your pants can catch fire. If I'm a foot away from the unit I can't feel any direct heat from the unit My unit is about 12 inches from the side of the garage and the side does not get hot at all. There is no flame other then inside the unit.

Re: Temp Heat in Garage
Since I'm stuck in Minnesota for the winter, I decided to buy a 17,000 BTU infrared electric heater to quickly warm my work area. It does this quite well and was not too expensive ($109.95). It does have some disadvantages; first, it needs a 30 AMP 220 volt outlet. Luckily, I have one of those for my welder. The second problem will probably make itself evident when I get my first electric bill. The knock on electric heat has always been the cost; I'm sure I'm in for a dose of reality soon. Oh well, hopefully it's only for this one year.

Re: Temp Heat in Garage
I used a $10 infrared lamp in $9 reflector socket over my workbench and a pair of coveralls. Keeps your hands/front and small workbench area warm and provides extra light. I also moved it around for working in the cab or under the car.

Re: Temp Heat in Garage
Electric heat source always the most expensive. Kerosene, even K-1, does not burn completely and deposits an invisible soot in the space (I know this well).
Don't use anything that obtains combustion air from the garage itself. Compared to other gases, gasoline and LP gas fumes are heavier than air and settle to floor level which is why most building codes require a garage attached to to house have its floor level at least 18 inches below the floor level of the house. |

Re: Temp Heat in Garage
After what "DrBrown" said, I will add again that I have a Carbon Monoxide/Gas Fume detector that plugs into a convenient outlet. It's cheap insurance (though they can be annoying if you want to do "just a short test run" of your car).

Re: Temp Heat in Garage
If you have the electricity for it they do make small electric hanging furnaces. You would want insulation though. I use a hot dawg hanging but have natural gas since in town. To late for in floor heat but next time, I do remember froze toes.

Re: Temp Heat in Garage
Having experienced it several times, I will agree with the assessment that in floor heat is the best way to go. However, it is about the farthest thing you can get when discussing "temp heat".

100 feet of gas line trench dug 18” deep..... Pipe in and held pressure for a week... Air return plenum built...filters ordered.... Furnace mounted,ready to get the sheet metal guy out here on Monday... Last winter it was no fun trying to get anything done when the shop was 36 degrees ....

Re: Temp Heat in Garage
I cut a hole in the heater ducting and put in closable vent. Works great in winter and summer for a 4 car garage.

Re: Temp Heat in Garage
Some low(er) heat/power consumption ideas:
If one has a hot water circulating home heating system it could be relatively easy to extend a supply and return piping to a garage area, incorporating shut-off and diverter/balancing valves .... however don't allow the water in the pipes to freeze. Hot water heating systems normally have a 15 lb or adjustable water pressure reducer at the boiler. This would work well with a ceiling suspended heating unit with electric fan and thermo control. Design your own device .... Got an old car radiator and electric fan ? Not as good .... with a ducted home heating system a supply air duct might be extended to a garage, with shut off/volume control damper, but one would NOT want a return air duct as that could return contaminate air circulating inside the home. Best idea .... put an old semi-worn-out but functioning flatie or diesel outside next to the garage with a small fuel tank. Use some steam hosing (sold by the foot) to connect it to its/a radiator inside the garage, and place a portable 24' box fan to blow air thru the radiator. Fill the flatie with antifreeze. Listen to its music as you work. Tell the wife to wear ear muffs. Idling the engine not good but its like putting a race horse out to pasture. Last edited by Drbrown; 12-16-2017 at 11:42 PM. |

Re: Temp Heat in Garage
I have an old oil furnace from a home in the shop where I work on stuff. It can get the temp up well into the workable range for me. I don't use it a lot. I have to be pretty inspired to get out there some days when its in the minus 20s outside. Also got a space heater. One of those "rocket" deals that burns anything from kerosene to tractor fuel. I'll use it in the big , well ventilated machine shed some. In a smaller, less ventilated shed it produces enough exhaust to make your throat burn after a while. They tell me kerosene burns a little cleaner.

To gain more heat, bolt on an automatic transmission, lock the output shaft, and put it in drive. Run the cooler lines inside to a trans cooler. Run the engine about a 1,000 RPM. The shearing action of the fluid in the torque converter makes a lot of heat. Since we're cutting holes in the wall, add two more and pipe the exhaust inside, through a large muffler, and out again. Use the hottest thermostat you can find. You can even add an engine oil cooler and get back even more from the gas you're burning. How close to 100% efficient would this be??! No heat lost up a chimney! Apply for off road use of fuel and get the hiway tax ($.20/gal. or more) credit. |

Re: Temp Heat in Garage
Personally, I wouldn't use anything that has an open flame. Gas/lacquer thinner, etc vapors can and do get into places you can't put your hand. If I had a propane or NG furnace I would box it in outside the building and duct only the heat in.
I have an in wall electric furnace (fits between studs) in the heated part of my pole building. The heating element is about 7' above the floor and the hot air comes out floor level. I know that isn't temporary but please be careful of anything with a flame. |

Re: Temp Heat in Garage
I have a Pellet Stove that I got last year. It works really well, uses outside air for combustion & exhaust. In use it costs about 5 bucks a day to operate (all day)
Shop is 24 X 32, fully insulated, except for the (2) 10' doors. Takes about an hour to make it a comfortable 65 degrees. |

There are some pretty nice jet heaters out there - just find what's your cheapest fuel to heat with, get the place warm with that than maintain it with the other. Nothing about this hobby is cheap I can tell you that but it's our passion ... (chuckling) .... |

Re: Temp Heat in Garage
One advantage to working in the 10 degree temp in my shed yesterday was that I hardly felt any pain when I hit my hand with a hammer yesterday. Typing a little slow today though. :-(
