    Any direct vent propane unit heaters?

    For dusty areas, you may want to consider a tube heater. No fan to kick up dust. More efficient also. There's a collar on the burner box as standard if you want to hook-up flex duct for fresh air intake. Here's an example: http://www.h-mac.com/detroit-radiant-ld-20-40.html

    Replace overhead Modine heater w/ something quieter

    waste oil heater

    If you have the waste oil, great, it's typically a 2-3 year payback. If you need to purchase the waste oil, it's probably not a good investment. People often complain that they are not reliable. They definitely require more maintenance then most other types of heaters. If you follow the...
