If you remember, I have a AHS Coalgun S130 that I'm going to use to heat my 1000'-sqft. barn. I've been looking around for a used Modine unit but a decent one hasn't come along. I work in a body shop and we happen to have a F450 diesel ambulance that hit a deer. The intercooler is slightly bent and we're replacing it. I got looking at it and it sure would make a nice heater unit. It's about 2'x2' and has two large ports I can weld female pipe fittings into. I can build a box around the back of it and mount a thermostat-controlled fan inside. Hang it from the ceiling, run a couple pipes and Bob's yer uncle. What say ye? Dumb idea or not?
