Garage Heating Solution

[Maximum404]

I have a ~600sqft garage that is insulated on 2 sides. The other boarders a bedroom/bathroom with a 10,000BTU PTAC installed in the bedroom (~220sqft) for Heat and A/C. It is below the master suite. Two car door with one side entrance and a set of stairs to the main house.

I have read a lot about a 120V solutions being inadequate for 600sqft, but my panel is maxed out at the moment so running another 240 line would be a rather large pain (new panel).

Assuming I go with the 120V option, would I be better off with a 1500W infrared vice ceramic? I plan on setting it to 60 and just forgetting about it. Recommendations? I was planning on picking up one of the following two models tomorrow:

Side note, this is really just to help the PTAC heat up the space since I leave the door open and all the plumbing for the master above is not insulated to the garage (also working on that).

Another option would be to install an LP heater and run a new line to my tank, although it is a rather small residential tank. I currently fill it every 3-4 months.

I think the propane would be the best option, not sure what your budget is, but get some unistrut, some 2" venting, and hang a small 90+ gas furnace on the ceiling somewhere, you need minimal duct work if any.

You can get a 55K btu furnace for $500ish, I can install one on a ceiling in less than 3 hours all done, I have done it many many times, right between the two garage doors, I make a small supply plenom that blows 45-90 degrees downward depending on the layout and let the rurtn pick up off the ceiling, just a grill grate and .99cent 1" blue fiber filter...

2" vent to the outside, 3/4" gas tite or trac pipe, 18-2 for the thermostat, and 12-2 for the power supply 110-120v.... a 10 fet piece of unstrut cut in half, some threaded rod and the rod vipers (it accepts 3/8" rod on one side and the other side drills right into your joist) I run 4 and they hold perfectly...


I like them ofver the hotdog, mr heater type hanging units, because they are more straightforward, easier to repair, dont break as much, much more efficient, easier to vent, etc etc etc...

Sounds perfect, but do you mean an actual home furnace such as this?

Yes. They are pretty small. Really just need an intake filter to keep the heat exchanger somewhat clean. Perhaps a short exit duct to keep stuff out of the heater and direct the air to where you want it.

What are you doing in your garage?

There are also forced air units at big box places and online:

"hot dawg" or "Big Maxx" or similar.

They all need an external vent though. Combustion air needs to go outside (along with the moisture from it).

Nice thing about the "household" heaters is you can get 95%+ efficiency. Those garage heaters are probably 80% efficient on a good day.

They all have jet kits to convert from NG to LP and back.
