i have been searching fora couple of days and i cant seem to find info on the harmon sf1500 furnace. it seems to be what i want but i dont even know how much it cost or reliablity of the unit. it seems to me that no company post there prices on the internet which makes it hard for me to pick a single unit out from another since i am in iraq and i wont be home untill mid november. i have 2500 set aside for this project and i dont even want to spend that much. my current setup is an oil fired boiler that feeds old iron radiators with steam. i am thinking i want forced air because i know i can run air ducts fairly easily. what i also like about the sf1500 is that it can run on wood or coal. any info or suggestions will be greatly appreciated.
