I have been looking for a heating unit too. Have two bay garage. Want to use a convection kerosene unit that puts out 23-25,000 btu. Is that too small a unit? Would it take the "chill off the area"? Do they take hours to warm the area? Cold winter temps here are 20's to 30's most of the time. Garage is attached with rooms over it.

Propane burns cleaner with less odor IMHO but you still have to look out for CO.

I'm using the 4800W electric construction heater but it doesn't get the garage warm at all (uninsulated, 20' X 40'). It's good enough to make it O.K. to work in though.
I stayed away from a combustion type heater because of the combustion products. I don't see how any unvented kerosene or propane heater can be safe in a garage because of build-up of CO2 and depletion of oxygen. If anyone knows why they might be safe in a confined space, I'd like to know how.

I have the big sister to this. Believe me. It's worth the PITA to run the natural gas!

Heats the garage up in about 30 minutes. It's off the floor ( no open ignition sources on the floor IMHO, too easy to ignite those gasoline fumes

My garage is an attached 24 x 31. On the colder Virginia winter days I use two 22,000 Btu kerosene heaters to warm it up. Once warm I turn one off and the other unit does fine. I start the heaters outside and turn them off outside to minimize the odor.

I have a heater that hooks into my hot water heater uses the hot water to heat the air, cost about 300 US. added $20.00/month to my gas bill but works great.

Do they still make those used oil fueled heaters???

I love the Kerosene fired reddy heaters. They get things nice and warm in a hurry if in an enclosed and somewhat insulated garage. Here in Oklahoma, we very rarely see sub zero temps... usually in the teens overnight and 40's during the day in winter. The last reddy heater I used would run you out of the garage with heat in a half an hour.

They smell cool too... kinda like being at the airport.

Desi,

I used to use the construction type heater in my 24 x 24 insulalted garage. It will do the trick for what you want. I finally went with a wall mount gas furnance, cause I spend alot of time in there and wanted a fully heated garage.

I have my used construction heater, and you can have it. It needs a male plug on the end, I cut it off and used the plug for something else, I don't even remember what for.

I have a Modine Hot Dawg heater in my 2 1/2 car garage. It runs on a thermostat. Does a great job and very satisfied with it.

A wood stove is a great idea for cheap heat and if you only need to use it sporadically.
The only draw backs are:
1)The need to chop wood into smaller junks
2)It's dirty

I want my garage above freezing all winter.
I have isolated it to two options.
1)In floor water radiation
2)On floor big azz radiators.
My house has hot water radiation heat, so I can either tap into that system or just buy another hot water radiation furnace for the garage. This way I can connect the garage and house systems with a tap valve and have a back up both ways.
Those hot water radiators are good, but I am unsure as to the amount of sweating through the unheated cement floor that might take place, which is not good for car chassis's

I've got one of those hanging electric heaters in my 2 1/2 car attached garage. It has a pretty good blower and thermostat. It mounts up high on the wall and works best if I turn it on about 30 minutes before I want to work out there. I usually use it when I'm washing or waxing in the winter. It works great for what your talking about. I wouldn't recommend it if you wanted to heat all the time, propane would be cheaper for me.

I use a 240VAC, 5KW electric heater in my garage. My garage is a small 2 car attached and pretty well insulated. I can keep it 70 inside in 25 degree weather. Since your garage is attached I would stick with electric or a natural gas furnace type of unit or the smell and fumes may get to you. One of the better garages I have seen is a guy that uses a pellet stove to heat his. They are cheap to run and can put out a ton of BTU's when needed, and no chopping wood. Just pour in the pellets.

I have a construction heater like the one in the picture you posted. It heated my old garage up enough so you'd be in your t-shirt... this was only a 12' x 25' garage. As long as you have 220V available in your garage you should be fine. turn it on and hour before you go out and you'll be fine.

My new garage I'm going to run ducts from my furnace into the garage. I just have to find air tight dampers that open and close with the furnace fan turning on and off. Idon't want the fumes and smoke getting to the house.

ive been using a kerosene salamander to heat my 16x28 insulated garage ,but now that i upgraded to a 200 amp service for the house im installing 4 -8 foot electric baseboard heaters.My whole house is electric(everything) ,so why not add them out in the garage too.I use programable thermostats in every room and my highest bill so far is ony 194.With the salamander it gets too 95 degrees in the garage.

I have a 40,000 propane heater that uses a bbq tank. Have had it for years - heats up my 24 X 24 attached garage (insulated) in about 30 mins. Its a Coleman, bought at Canadian Tire for around $250. Works like a charm - I live in St. Catharines, Ont. and it does get chilly here. Heater takes the garage from about 40 degrees to 65-70 in about 20-25 mins and its cheap to run. I have a CO detector in the garage and its never gone off but my doors aren't insulated and there are a couple small leaks around the edges of the doors. IMHO it's the best way to go - cheap and efficient.
