I used a propane torpedo heater in a well insulated garage an it gave me a headache that lasted 24 hours. I was effectively giving myself carbon monoxide poisoning. The same heater in a poorly insulated garage could be run for hours and no ill effect.
I decided I was tired of headaches. So I installed a wood burning stove. Takes 30 minutes to get the garage to 70 from 30. It's a large two car garage and is well insulated.
