Move to Tucson Arizona!!!!!!!!!!

 

Picked up an electric unit that hangs in the corner at Home Depot about $200 I think. Heats a 3 car with no problem but garage is fully insulated + dry wall. Warm enough to work in T-shirt.

 

I have in floor heat and working on getting it all hooked up within the week.

 

Hell Toyrider I thought you had that puppy up on line already
Once it goes on line you will enjoy working on the cocncrete,
Best heating system out there for comfort

 

I use a little radiant heater. It is a sealed unit with oil inside. It's not a full time heating source. I use it for a few hours at a time. It is safe and effective as it has an auto shutoff function if it gets knocked over. You can buy them at Target or Wal-mart or under $100.00.

 

Oil furnace running on kerosene. I super-insulated the garage (and it's partly below grade) so it doesn't drop below about 49° even if the wind's howling and it's 0°F outside. I don't run the furnace unless it's below 60° and last winter I used less than 175 gallons of kerosene for the whole winter. Usually I'm in the garage a couple of hours every evening and most of the day on Saturday and Sunday and I'm never cold. It's a 1500 sq. ft. garage. This is near Pittsburgh, PA.

Insulation is the secret. I have 2 x 6 walls stuffed with fiberglass, and about two feet of fiberglass in the ceiling (less of course near the eaves).

 

A great sorce of quick and hot heat is Propane. Get a 20gal tank and a 3burner top heater. We use them in houses we remodel in the winter. you can use just 1 burner or 2 or 3 for different heat levels.Arround $120 bucks counting the tank. Also can be used in your home as a back up sorce of heat should electric power go out.
If she is afraid of gas take her to almost any car repair shop/garage and they are heated with natural gas ceiling heaters. maybe that will help

 

move your garage to southern Florida, she won't mind give her a pool.

 

When I built my house I took into consideration my hobbies, cars an motorcycles. I built a 3 bay attached garage with heat and AC. My garage stays almost the same temp as it does inside the house. It sure makes it nice to work on my toys!!

 

I have no idea where you are, so
As far as where I live, in AZ, I would see about running tubing through the floor and using solar water heating panels to warm the floor with. The heat will rise.
I also agree that insulation is a key element, professor.
You choice on what you would use for any additional heat. When I lived in the mountains here in AZ we would use wood burning stoves, cause there's plenty of wood and it smells pretty good. It does get a bit dirty sometimes, but I like to listen to the fire crackle and drink coffeewhen I'm watchin' the snow fly Family in town uses the solar water heaters even in winter in the mountains, so if it's not too cold where you live you may get by with the solar water heating panels. Use of a heat exchanger above the slab would probably do all you needed it to, at least where I live now it would for me. A solar panel or two to run the fan and I'm in business.
