As you probably know from my previous thread, I have just built a garage for the bike. I need to get heat in it soon but haven't decided what to use yet. I initially was going to run gas to the garage and use a small gas furnace but started thinking about open flames, vents, etc. and am looking into an electric furnace with an A-coil to allow for A/C in the future.

What are you other guys using?

 

There are a lot of direct vent stoves that have no open flame,some of the bros here could guide you.We have propane stove as a backup to heat our home,they work great.

 

Hang the Furnave on the ceiling and no worries about gas fumes as they are heavier than air.

 

vermont castings wood burning stove, direct vent when working on flamables. Looks like there are plenty of trees around you. Remember that your light bulbs and electrical outlets are open source of sparks.

 

+1 on the ceiling setup, you can get them with AC too later if you want it.

In floor heat is the best but its a little late for that.

I use a propane heater and it works great, nothing fancy but my garage is not nearly as nice as the ones that thread....

 

You could always run a pellet stove, they work great and are a great price compared to others.

 

i have a small electric heater i got from northern tool supply that attaches to the wall up high, heats a 20x20 real easy

 

Electric baseboard for heat, and a window (or sleeve it in a wall) AC unit would be the least expensive and just as inefficient as a central electric furnace. Unless you want to spend even more and do a heat pump. Some good features with baseboard units is they put the heat down on the floor, they are quiet, no flame, no blowing air, and are easy to individually control. But locating them on open walls in a garage can be difficult and you want to have a lot of insulation above and seal that garage door really well.
In my last motorcycle room/garage, which was actually two rooms totaling 24'x36', I installed a small window AC and left it on 75-76 degrees, auto-energy saving mode, all summer. Worked like a charm keeping the humidity down too.

 

I run an electric heater with fan that runs on 220V. It does the job and keeps the cave nice and toasty. It hangs from my ceiling and is noticeable on the attached pic.

 

I went with Propane. External tank outside the garage, so it can be filled with the truck just pulling up about once a year.
