Workshop heating

[Jeff Fleisher]

I know this topic has been addressed before, but does anyone have any experience with permenant mounted kerosene heaters vs propane? I am looking at a Monitor 2400 kerosene heater for my workshop. It is a 20' x 30' shop with 10' ceilings. I also plan on insulating the garage door. The walls and ceiling are already insulated. I understand this type of heater is very efficient and is double vented (intake and exhaust to the outside). Anyone have one and can comment?
thanks,
Jeff
