I have a radiant nat. gas heater , about 10x 20'' roughly , laying on the shelf, if some one is interested in it . It will give u headaches in a small low ceiling garage tho-----------
Mine is a fan powered tube heater...never any fumes. But a std. radiant works fine in the right area. I' ve been inside countless ag buildings where they are in use....high ceilings is the key
