Kerosene heats well but I can't stand the stink and hassle of buying kerosene.
I like those portable radiant units they heat up my 2 car garage fast. I looked at gas fired furnaces but decided I wasn't crazy about having an open flame in the garage. :flam: The super safe garage furnaces are way too pricey for me.
A buddy of mine uses those
oil filled heaters(that look like old home radiators on wheels) to keep the garage temp from dropping too low then uses the radiant heater to warm it up all the way when he's working.
I think I'll pick up one of those oil filled heaters too to help keep my Bonnie warm on those cold Colorado nights.
