I am considering various heating options for my new garage, but I have one big stumbling block. I work 12 hr days, so I will be away from the house 14ish hours at a day on workdays.
If I want to keep the garage at a minimum of 5degC, I need infloor (not possible, concrete is poured), electric, propane or oil fired, right?.
I'm thinking on a small oil fired furnace (possibly from a mini-home), or maybe one of the roof suspended units. Anyone use either of these for their garage? Anyone have any general thoughts on the matter? How about legalities in NS?

I was under the impression that heat pumps are a poor fit for garages, since they are inherently lossy to begin with when it comes to heat.

Is the garage insulated? ASHPs are 3 to 4 times more efficient than electric baseboards. In my current office (15'x 28') in part of a 100+ year old building on piers, I have R-40 in the attic, 3 walls have R-12 (at best) and the front wall has 0 insulation and has a large single pane window (6'x 5') and a door. The underside of the floor was sprayed with foam (only about an inch) but still has air leakage along one outside wall. A 9000 BTU heat pump provides my heating and cooling.

It is actually in the process of being built. Builder is leaving the garage unwired and uninsulated/unfinished on the inside to keep my initial cost down. My friend is an electrician, and I will be insulating it myself. 26x30, vaulted ceiling with 15' inside peak. Full 4' frost walls were poured with the pad, since it is large enough it had to be engineer approved.

A mini home furnace is my next heating solution once I get more space. Or if I can get 220 out to my garage I will be going to hanging heater like creepy has. I have a kersosense/diesel heater now 125,000 btu, the thing is insane but it's smelly and I have to run the sucker fan to exhaust the fumes. I can get my 320sq foot shop to 40 degress in 20 minutes lol.

I'd go hanging overhead electric with digital t-stat to control, or mini-split heat pump. There is a big heating thread a few pages back in the shop and equipment forum. Here's my overhead unit thread: Can't beat the price. shop stays above freezing when I'm not home, and I work at about 15deg. Takes about an hour to get warmed up. nsjc.proboards.com/thread/35106/cheap-easy-heatNow that I have some heat pump experience, I think they would work in the shop environment. bonus to have the digital controls and timers built in. Set it at 5deg for your shifts, turn it up an hour before you go out to the shop.

I know guys that have mini splits in their garages but they don't seem very practical to me. Heat pumps are even heat, not quick heat, and if I understand correctly, the minimum setting is something like 15-16°C, not what you are looking for.
To burn oil your tank will have to be approved by your insurance company, and if you want warranty on the tank the cheapest install is going to be $1000 or close to it. Ask your insurance broker how much more oil will cost than other sources of heat. You lose quite a bit of space for furnace clearances too.
Wood stove is an option with electric backup. You still lose space, have to deal with the insurance company, have a chimney, and have to process and store wood. A couple of used electric baseboard heaters, a thermostat and a breaker and you're good to go for quick heat while the stove warms up.
Electric thermal storage may work well for you, ETS. It's electric that heats up at night and lets the heat out when you need it. Rates are 1/2 price at night, but 4 cents more than the normal rate at peak times of day in the winter. It wouldn't work well for a shift worker who was home through the day, but would for a day worker. After 11 at night, weekends and holidays are 1/2 price. Basically, except for a few months in the winter, your rates are normal or 1/2 price. All of your grinding, welding compressor etc would be 1/2 price on weekends and holidays. Not sure if they would allow an install in a garage.

I didn't know of the min. setting on the heat pumps, that's a deal breaker for a shop.

A heatpump can be geared up to do... whatever you want. I had a look at your other thread and, with all the ground water, you have an IDEAL situation for geothermal. They make small (I'm talking real small, like 2' x 3' x 12") geothermal units which you could hook up to your garage, get yourself a heat ex changer (part inside that blows air around) and you'd be set.
Go talk to a real HVAC outfit (not someone who installs mini-splits on the side after watching a bunch of youtube videos)
The temperature limitation above is a function of the built in thermostat on some units. With a real thermostat you can run them much lower.
