Being the DA that I am, I didn't put a heater in my garage when I built it 2 years ago, didn't even wire it for one. But after the Middle Tennessee recent single digit temps for 4 days and my dogs being in the garage I'm wishing I would have thought of this before. Anyway, now I am looking to install a heater in my 24*32 garage. Nothing major just something to knock the chill of in the winter. Anyone got any ideas that are reasonably priced? Thanks

If your garage is insulated, you shouldn't need any heat in your warm climate. Up here it has been -20 to -30 at night for the last 5 weeks, and 0 to -10 in the daytime. My well insulated garage with no heat is maintaining itself at +20.
You should be easily able to keep your garage at +40 to +50 degrees with no heat if you have it well insulated.

Like Gary mentioned, insulation ? Any thing you put out there is going to be about worthless without insulation.

If it is insulated, I'd suggest an electric oil filled radiator. It should be reasonably safe with the dogs out there.

Yes it's insulated but it is always cool out there. I have a small one of those radiators from home depot but it don't heat it very good.

I was just looking into exactly the same question... have a 25x25 attached, insulated garage.. been thinking of just getting a thermostatically controlled plug-in heater so it will be ~40-50 degrees in the morning. Not a huge deal but it would be nice to keep it a little warmed over for the daily drivers. Only a concern during these super cold spells that we've had recently... last winter I barely had to wear a jacket.

Every year I say I am going to grab one of the many reznor gas heaters of cl that I see...needless to say I don't have one yet. I still use my kerosene bullet. This year has been particularly cold in northern RI. Anyone have one of these gas units that hang from the ceiling. What size do you have for what space. I have an attached 2 car which is 30x30.

I have a G37 and its o.k. What helped the most was sectioning off the shop.
I am in the process of insulating 2/3rd of my shop. I'm not done but already its amazing how fast that little heater can add 10-15 degrees.

That heater sure doesn't look to be sealed. I personally do not like heaters of this kind for the garage. I think it could be hazardous with gasoline and/or any other combustible item in the garage. Just saying....

All the moisture from those heaters goes right in the building too. I would avoid it for long duty cycles.

Do you have easy access to natural gas line or the ability to install a propane tank outside?

If not look at the Dayton G73 I have one in my 20x20 garage with an uninsulated door. It will heat the garage up nice on the coldest of days. I just had it running out there in the -30 weather we were having to keep the batteries from freezing.

Great little unit, if you can grab the external themostat, much easier the climbing the damn ladder all the time to change the temp!

My nat gas reznor 60k is my favorite thing in the garage 6 months out of the year! I keep it at 58° and turn it up to 64° when I'm working out there. R13 in the walls and R30 in the ceiling. Think I've got a total of about $900 invested in it, and it was worth every dime!

I just installed one of these:

It has been very good so far. Take a little while to get the entire garage up to a good temp, says it will handle up to 600 square feet. Cost me $90 plus $20 to wire it in. Worth the money the last few day when it was 6 degrees here in Maryland.......

That's what I want. Where did you get that one and for how much. I will tap into my gas line so I don't have to worry about filling anything. Looks smaller than some of the reznors I have seen on cl. Very nice location. Mine will be in the same spot.

I am not a big fan of electric heat, but TN has pretty low electric rates.
I would look into high mounted electric IR heater.
You can aim them to where your need the most and it will spread to the rest of the room.

Yup. Those are the worst variety of heater to use in a garage or any building you actually plan to spend a decent amount of time in. Theyll rust the **** out of your tools and Ive ever seen folks have issues with mold bc of them.

I just bought a Beacon-Morris 45k btu vented gas heater for my garage. 11% off at Menards for buying a gift card then another 11% off for buying the heater last week. Im into it for <$350, but admittedly I still need the vent stack. Simultaneous to installing the heater tho, Im also pulling 220 out to the garage and adding a subpanel to power everything independent of the house.

Soon enough I will have plenty of power and a roasty-toasty 70F+ garage to play with my machine tools and toys in.

The Dayton G73 is the exact same unit at the Fahrenheat FUH54. The company Marley makes them both but just slaps a Dayton sticker on it for Grainger. I just installed one in my shop 2 weeks ago and it works just fine. I paid $229 for it at Farm and Fleet. I wired it with 10 gauge wire on a 30A 240 breaker.

Those ventless propane heaters ****. I have tried two different units. They stink really bad. If I worked in garage 3 or more hours I would get headache and wierd feeling. I would crack window for vent and used a CM alarm. Replaced it with a electric furnace that I bought from a HVAC business that removed it from a condo. When the AC units go bad the whole system needs replaced. Furnace was $100 and duct was $60. My brother and I hung it from ceiling in 4 hours. Bought a garage thermostat from Menards that I set at 35 degrees and it does not freeze.

Ditto. Quick and easy installation provided you have 240v available. I use the Farenheat FUH54 to heat approx. 1500 sq ft that's well insulated and it works great on the low setting. Keeps it 60 degrees 24/7.

Don't use a ventless for 24/7 heat! Your dogs are alive and I'm sure you want to keep it that way.

I bought a 220 volt electric portable heater from Northern that works well if you have a 30A plug out there. Mine heats a 12X24 section of my shop no problem on it's low setting for about ten bucks per month. We just had some freezing weather with lows around minus thirty degrees and it still kept things at fifty to sixty easily.

5000w electric as a minimum would be my thinking. Search for the G73 Dayton type posts.
^^^^^^^^^^^^^^^^^^^
This, But the Fahrenheat is the same thing for less money.

EDIT

I've got one of the ventless propane heaters in my shop, 30x40 insulated and it does well. Haven't had any mold issues or rust issues either. And the winter air is always drier then the summer air so the added moisture that they do put out keep your skin from drying out. IF you have moisture issues you can always run a de-humidifier.

I really like electric heat, given the requirements meet your needs. It is clean, quiet, easy to install (assuming you have the necessary service), and total cost of ownership (unit price, install price, operation, etc.) is not too bad. Of course, if you spend lots of time in your garage, electric might not make as much sense from an operational expense standpoint.

My old garage, 18x24, R13 in walls and just OSB in rafters I had an electric heater with built in thermostat. Just sat on the floor next to the 220 plug. When I needed to use the 220 welder, would just unplug. I only had 30 amp service out there, so I could not run both at once. Two settings, I think 3200 watts and 5600 if I remember correctly. Worked great! Have any temp I wanted out there any time of the year. When not in the garage I would dial it back to 40 or so to keep it above freezing.

I have one of the ventless blue flame heaters in my basement. Works great with no moisture issues. I'm planning on getting one for my garage.

I bought a small propane torpedo. It works but is loud.

Also I would recommend the Dayton electric heaters they work great. We had them at work. No issues they were on all winter long. Even with high ceilings the heat was great.

I just ordered a 30K-60K forced-air propane heater for my 24x48. Supposed to heat up to 1250 SF. We'll see. Most of my garage is insulated-enough to notice it's colder in there when it gets warm outside and vice-versa. But in order to finish it, or work out in it, I need some heat. This was the best option for now until I decide I want something permanent in there. Most have said they heat a garage like mine within a half-hour or so, and then you can turn them down to low, or even off, depending on how long you want to be in there. One thing for sure-they're a ***** to find right now.
