Could people share their opinions and advice? Is an open
flame heater dangerous? What type of heating do you use?
Any recommendations to heat my shop: it's about 20x20
with a 12 foot ceiling.

Thanks,
Dave.

I use propane. I'd use natural gas if it was available. Electric is
expensive to run, but more of a cost of running enough power to get enough
heat. A 1500 watt heater is only 5118 Btu. I need at least 30,000 in my
detached garage. When the temperature gets very low, say 20 degrees or less,
I don't even try to heat the shop.

What is best for you? Depends on many factors. Insulation? Coldest
outdoor temperature? Fuel availability?
