Just looking for some advice, hope its not a problem if I ask in this section. I am trying to decided if a diesel, kerosene or propane heater is the way to go for my garage. I have lived in warm climates most of my life so am not very familiar with the pluses and minuses of the 3. I am looking to heat an area about 10 foot high, 12 foot wide and 20 foot long. The place is a rental so I am looking for something like a cunstruction site "bullet" heater. I am figuring I will need somewhere between 75,000 and 125,000 BTU's. So please help school the new guy so my wrenches are no longer freezing to my hands.
I just have one of those little forced air heaters that hooks up to a propane bottle. I don't remember what the BTU's was but last winter in the garage I had that was similar to size of your's I could start it up about a half hour before I wanted to work and open the overhead door about 6 inches for ventilation and when I went back out to work I could take my coat off and be fairly warm yet. It is very portable and the propane seems to last a long time. For me, I didn't want diesel gelling up when I wanted to use it. Also, I noticed that the diesel/kerosene ones seemed to be more expensive for the amount of BTU's compared to a propane one.
One man's opinion. And any heat is better than no heat!!!!
