How about a waste oil heater.  I've seen some large
automive shops heat their shops just from waste oil.
DO a google search on waste oil heaters.

 What is the groups suggestion for heating a 40x50 insulated hanger. It
 doesn't have to be hot I just want to raise the temp about 15-20 degrees
 when it is 30-40 outside.
 Here's the rub. No natural gas available plenty of electric though including
 an unused 220 connection.
 To see the hanger visit www.peoamerica.net/N601WR look in the contact me
