I have a 24x30 insulated garage that I'm getting ready to look at heaters,I have a budget of about 1000 to do the job,I can do the install myself.I was all ready to get a mr. heater tube heater 10ft I would have to run propane as my fuel source.But I hear that they really use a lot of propane to run?I live in the northeast and it can get in the 20s though out the winter months.Can anyone that runs one of these give me some input or some other choices of heaters that you have had luck with,there just so many choices I want to make the right one...Thanks..ED
