We have a number of options if you wish to do some heating with propane.  We have Patron heaters that put out 40,000, 80,000 or 195,000 BTUs of heat.  These are very efficient and can be used inside a jobsite.  We have a range of different sunflower burners.  We have larger 350,000 BTU construction heaters and a number of other heaters between sizes.  We rent out propane bottles that go out full and that the customer refills before returning.
