For those of you that have tables outside your house like say a garage or a building how do you heat it. My Son has looked into propane but it seems quite costly getting started. He is still working on finishing up the inside with insulation and walls. He has been running a oil filled radiator heater but it seems to not do as well of the evening when temp drops. I hate Kerosene as it gives me a headache and hate the smell it they do heat really good. I read you can put a pan of water on top to kill the smell. Just looking for some ideas and the best route for heat for the building. It is a 16x24. I did not want the pool table to smell like Kerosene either lol.
