Can these be used to heat a 30x40 insulated shed?

IMOP yes but the propane will be pricey! Do you have NG?

No we do not have NG. Our options for heater are elctric or Propane. Minnesota winter can be cold

I'm not an "appliance" guy but a lot of heaters, clothes dryers, ranges, etc. that are usually factory shipped for NG, but can be converted to LP with a nozzle change. You might be able to contact the manufacturer to see if they sell a conversion kit. Sometimes this information is on a lable of the unit. You might get lucky and give this the due dilligance that the seller did not. THis seems like a good price, just keep in mind that most "construction heaters" require venting and are not recomended for closed spaces.
