 North West IA/western AZ | If you like the 150° air coming out of your oil fired unit, you will not get that with the Geothermal. It may be closer to 90°, but it will keep you warm much cheaper than the oil burner so you can afford to turn it up. You do use the same ducts as a modern oil burner. If you have an old coal burner converted to oil, you may need new ducts too. | |
