Best way to heat garage
I have a 24' x 36' x 11' high insulated garage that I would like to install a heating system in. For years I just turned on a small propane heater to get the chill out but would like to find something cleaner to run. I'm not looking to keep heated all the time just something strong enough to quickly get the chill out. I was thinking of a suspended propane or electric unit.
Thank you. Peter |
I have a smaller garage than you do, but I have found the oil filled electric radiators to be decent. Not sure if it would heat your space though. But they are clean and safe.

My shop is about the size of yours. I have a 75K BTU Mr. Heater (propane) suspended from the ceiling. It's the 2nd best investment in my shop. The 1st is my lift. There is nothing like working in a warm garage when it's crappy outside.

I have a pellet stove with automatic thermostat keep it 55 all winter long and turn it up when I am working out in it.

I went with a ventless LP heater as I did not want the hassle of putting a vent pipe. My garage is smaller than your's at 22x22. The heater that I got can be either free standing or hung on the wall. The hose is long enough that I could move it to where ever I am working on something but it does such a good job even in really cold weather that I just leave it where it is and turn it up when I plan on working in the garage. I have left it on all the time when I planned on working in the garage and, at the lowest setting, it keep the garage at 50-55 even in the coldest weather that we have had the past couple of years. When I have turned it down to just the pilot and then turned it up for ad hoc work, it was warm in less than 30 minutes.
Right now I have the unit in free standing mode but will probably wall mount it in the near future just to gain some floor space. |
I had a 24' x 28' - 2 story garage, that was insulated. I found a used furnace from a house for $200. I had a heating/cooling person switch it to propane for $100. I ran the gas line, and ran one vent line for downstairs and one for upstairs. Downstairs I just had 3 T fittings dumping the air from the ceiling, funning between the floor joists. Upstairs I ran vents like in a house. I kept the thermostat at about 50 degrees all of the time, and when I went out to work in the garage, I would raise it a bit. Normally it cost me around $300 a year to heat the garage.
I sure miss that garage! |
anybody ever use a 220v heater? i'm looking to heat the shop also.

Keep in mind that exhausting hydrocarbons inside your shop also adds moisture. Depending on your climate this may or maynot be a problem.

In the floor heat
I blew it when I built my garage. Radiant Floor heat is the way to go if you are going to heat it all the time. Nothing like laying on a warm floor. I have been looking at electical mats that will keep my feet warm but I don't know if they will do the job in New England. I guess a propane space heater is the way.
If you have ever been over to the Garage Joural there is alot of good information on that site.http://www.garagejournal.com/forum/index.php |
I have a 24 x 30 garage with a office upstairs and heat it with 220 electric ceiling mounted heater. It's set at 45 all the time and when I want to work in the shop I just turn the heater up a couple of hours ahead of time.

Move it to Florida...

Lift the hood of your Cobra and let it idle for 5 minutes.... works every time. (But make sure its well ventilated) :3DSMILE:

A TIG welder on thick aluminum is a good heater but the Modine style ceiling mounted seem to work pretty well and be good for not hogging valuable shop space. Like John I blew it also knowing I should have gone radiant in the floor. Trouble with that is it takes a while to come up to temperature. You have to run it kind of consistent and a little low. I finished up with a trailer hot air gun tucked in one corner of the shop. It does a reasonable job.

I already have 220 wired to my garage so my electrician is looking into an electric ceiling mounted heater. Did a search on garage heaters and found many people happy with this set up.

I first heated with the same style electric heater in the above post and still have for a backup. It is however extremely expensive to operate here in New England.
My pellet stove goes thru roughly 2 1/2 tons per year and my Garage is 24X26 and two stories. So it costs roughly $800 for the year to heat. My monthly Electric bill in the winter when using the electric heater in Garage was anywhere from $350 to $400.:eek: The heater depending on temps would easily add $150 to $200 per month to the bill. Electric is not the way to go in New England in my opinion. Marc |
A 75k btu gas heater would work best for you. They heat the space up very fast. Electric heaters dont have nearly as good a recovery rate. Radiant heat is the best but it doesnt have as good recovery rate as the forced air. So a hanging 75,000btu(minimum)gas heater is probably your best choice.
|
My heater is suspended from the ceiling as well and my garage is about the size of yours but my ceilings are taller. I use a 45,000 btu natural gas Reverber-Ray infared heater. Works great and I keep mine set on 50 deg until I need it but I never have it above 65degrees and my additional heating cost is negligable. Great investiment and I bought it used for $100 at building materials recycle shop.

I went with a counter-flow house furnace. it blows heated air across the floor first and then recirculates very easily. unless you can move volumes of air easily, alot of the heated air hugs the ceiling. I'm usually pretty close to the floor. once the floor gets warm, it stays that way for a pretty good while. Takes care of the snow that drops off the cars!
