garage heater recommendations

[Bob Sawyer]

I have the 5,000 box heater in my fully insulated 24' X 24' and it keeps it toasty.

LOL I moved to the knoxville, tn area

OK, then two space heaters.

I have an old forced air furnace that came with my house over 16 years ago and still works great in the upper left rear corner of the garage. I keep it at 50 all winter long and bump it up to about 62-65 or so when I go out to
Work on something. It's nice to go out even when you just need a screw driver and all the objects aren't ice cold out there also. The older I get the more I want to get some sort of low cost central a/c for out there in the summer. All brick garage with glass block windows for security so I can't do a window unit.

nice setup!I call those unit heaters,gas or electric!a mini split would be perfect to add ac easy install with just lines through the wall and would likely run cheaper than the unit heater unless it's on nat. gas!you could maintain temp with the split and boost quickly if needed with the unit!

GREAT LOOKING GARAGE.....
My concern would be combustible fumes and vapors that may come from the vehicles or from any repair chemicals (body fillers, aerosol sprays, paint, etc). Unit heaters get their combustion air from the surroundings, making them vulnerable. Perhaps the owner should consider a furnace with a sealed combustion system, which sources it's combustion air from outside or consider a condensing type furnace or a heat pump system that could be an A/C system as well.
B4 proceeding, the owner should investigate the local building codes to see what may be needed or required and definitely with his insurance provider. Usually, but not always, a fire suppression system MAY be required. In this instance, ignorance is not bliss and the "its easier to ask for forgiveness rather than permission" rule may not be applicable. If, in the event of a catastrophe, insurance may not cover the losses. Just my opinion of course.

Mini-Split air conditioner costs though.

Mini-Split air conditioner costs though.

I see ads for 15K/btu-heatpumps complete with line set everyday on ebay under $700-$1000 that would do that room nicely!

15000 BTU heating or cooling is not very much but the biggest factor to be considered is the square footage or qubic volume of the space to be conditioned (either heated or cooled) and to what desired temperature is to achieved and maintained. In addition, building's materials of construction, number of openings, etc.factor into the systems requirments. True, cost is a consideration but, if, what ever is installed, does not satisfy the owners expectations, then its money waisted. Talk with a person that does HVAC systems rather than just guessing or installing second hand system. Just my opinion of course.

I have two 3 ton mini split units in my shop. they work perfect are quiet and not hard on the power bill

the op is in tenn. that's got to be a good area for heat pump, no extremes!yes, keeping the doors closed is important, I don't think you need be an hvac engineer to know that! I'm in -30c winter temps. some days, I would need the unit heater as backup!
I've heated my house with heatpump for 30yrs. and operated 192,000 sq. ft. casino/hotel hvac so I've a little experience!
I would have suggested a chiller and cooling tower but he did say on the cheap!
