Inquiry (采购产品): sizing question I have a 22x35 building with 18ft ceilings that I will be using for a wood working shop. The floor is concrete and it has a large (16ft) overhead door (non insulated) on one end. The walls and ceiling are insulated low to average. I live just south of the Minnesota border in Northwood, IA. I would use the building evenings and weekends. I would plan on propane-based heat source and was looking at infrared heaters. What size/models should I look at and what would the costs be? How does infrared heating compare to traditional forced air? I have a portable kerosene based torpedo style 150,000 BTU heater that I can use to provide rapid heat up, as I understand infrared is slow to heat. My calculations indicate I would need about 150,000 BTU to heat the space. **** Hidden Message ***** Jeff Gorball 1377 430th St. Northwood, IA 50459 USA Company: Kingland Systems E-mail: gorballj@iname.com **** Hidden Message ***** gorballj@iname.com
