New Moto Guzzi Door Mats Available Now
I use one of the oil radiator type heaters for my garage. It will not make it warm but will keep it from getting below freezing. I keep it on high 24/7. Really does not cost much to buy or run. We are in the low 30's with highs in the low 50's. Just a light jacket in the AM to stay comfortable.
For safety reason's I would avoid anything with flame.
Not if it's done correctly... The National Electrical code is quite clear on this, at least for commercial garages....Anything that may produce sparks must be 18 inches or higher off the finished floor....To include all electrical outlets, lighting fixtures and motors... Other codes say the same about heating devices....This rule should be followed for a residential garage.... A hanging gas fired unit heater or gas fired radient heat is safe and what you see in commercial garages...
Exactly, I had a hanging gas fired unit for years and it produced no smell and was completely safe and efficient. And it's way cheaper than using an electric heating unit.
I'm in New England and my garage is about the same size. I have a gas line in the garage and I got an estimate for around $700 to put in a gas heater, but decided to just try an 240v infrared space heater first. I ordered this one from Amazon for about $120 and it does the job. Small and efficient.https://www.amazon.com/gp/product/B003XOZN7A/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
Proof positive that you can learn new things..I always thought the fumes would collect at the ceiling; thank heavens I never tested my obviously wrong theory.
I heat my garage with a natural gas over head furnace. Fan is a bit noisy when it kicks on but it warms the room up guick. Just turn on the thermostat, nice and easy.
Modine Hotdawg model HD30AS0111 NG heater or if you want to KISS a $50 kerosene heater off of CL.
Now that is a work space I could hang out in.
