Minisplit, propane, pellet stove options

Ok I am wrestling with this one and would be interested in some opinions. Here is the deal. I have a newly built 28 x 36 detached garage (T1-11), 2x6 construction, 12 foot walls with walk up loft area above that has knee walls on sides so open access on both sides at the end of the trusses. No insulation yet but will be bat insulating walls and roof and then closing walls off with shiplap or barn board. No plumbing unfortunately. First floor cars and tractor storage and mechanical work, second floor woodshop. Hobby use, weekend and occasional after hours use mainly. Location in northeast so heat is primary concern, but cooling and limiting humidity in the summer (and falls like this one) would be a plus.

Here are the options I was kicking around

1) Pellet stove - mainly because I have one in my main house and another in a second home, buy pellets in bulk and am very familiar with the stoves. Cost probably $2500-3500 might make it the most expensive up front and loading a bag of pellets each day might be a drag although I probably would end up only heating when needed.

2) LP Propane furnace - no NG in my area so I wasn't thinking about this until a neighbor offered me a next to new 120k BTU Comfortaire furnace that he used a temporary solution (less than a year) while his home was being built with geo-thermal. That size seems like it would be overkill for my application but it got me looking at other small options like Modine Hot Dawgs. Seems relatively inexpensive although I would have to get a larger propane tank.

3) Mini splits - I didn't know much about these but you don't have to spend a lot of time on this site to see they are popular. Having AC would be nice and they are probably the least noisy option which is also a bonus, but seems heat (my primary need) is not their strongpoint.

So given my situation and those options (or others), let's hear some opinions.

When I first built my barn I put a wood stove in it, it does a pretty good job heating and I don't mind messing with it and can get firewood, it just takes time to warm up initially. I just finished off about a 500 sq ft section of my barn, I put a mini split inside that area and it works great, its currently 88*-90* outside and nice and cool inside. I spent about a $1000 on my wood stove and piping and right at $1000 on my mini split. I did just order a wifi dongle where I can turn the mini split on, adjust temp ect from my phone, where it can be comfortable when I get there (or when the boss gets there) I'll see how the mini split does on the utility bill, I have really just fired it up yesterday. AC is nice.

Same dilemma for me as well. I have a pellet stove I can put out there but it won't heat up fast and with oil/gas being low I have a hard time buying pellets as it seems the price has leveled at 250 a ton. Mine only lasts for 12 hours on a bag so think I'm going with propane and some kind of ceiling heater that I can kick on and have it warm in a short time.
I have a minisplit in my house and love it. These last few days have been bad for humidity and I can run this in a noncooling mode that just ***** moisture out. Looks like it's ******* outside. I also really like the quiet cooling. Hope to put one in the shop at some point

2x6 walls should yield you like an R-19 in the walls and that is decent for a shop and your shop is not overly huge. Once it's insulated, it will hold the heat nicely if you maintain it and keep the concrete warm.

I have a wood stove and burn a fire 2 out of three days during the Winter and it doesn't go much below 50 during the off day till I can get it started again.

What would it take, 5 minutes to dump a bag of pellets before you go to work in the morning? Small price to pay for a comfortably warm shop in the Winter.

Mini split may do the job, depends on where you are i n Northeast. In Maine there will be days that it won't. Southern New England there will be less days that it won't. Trying to keep it 50 or at 65 will be a factor also.

Hmmm...maybe a mini split in combination with a pellet stove would be ideal. Sounds like I can at least eliminate the LP furnace. Especially the 120k BTU unit my neighbor offered up. Way overkill.

That is exactly what I was going to recommend.
A mini split will take a long time to warm the place up if you only use it on occasion, and on super cold days, it won't work well at all. But during three seasons, you'll love it. A/C in the summer, and it'll be great for heat when it's still above freezing out.
I would look for a used pellet stove, as they are far cheaper than new, and you won't be using it full time anyway.

I put in a full split heat pump system with the understanding that if it doesn't heat well enough (i plan on running and extra 1500 watt electric heater when I am out there once week) I can/will add a pellet stove for next winter.
