I do like oil heat. Lots of moisture. My system is just hot air and without a humidifier or two it get's damn dry. Down to 10% often. Shuffle your feet across the carpet and spark a 1/2" long blue spark onto the light switch plate screws. LOL
I’m not sure I understand that. All forced hot air systems create the same dry air regardless of fuel type. The burner is separated from the heat exchanger that the recirculated air moves through so fuel type is irrelevant.
Maybe you meant a different type of system than forced hot air?
