lets talk low cost heater

just wondering if any of yaw fab.people or welders have thought of making a heater off of our exhaust pipes or muffler.That could be ducted back in side with a fan .Seem like it would be low cost an high out put ,heat right away idling or wide open.May be we could get Chris C thoughts on this too

All you need is a computer fan, they are 12 volt, cut hole in dog house and mount with direction blowing in the cab, in summer flip it so it blows cab air across the motor.

Yep, I would recommend finding a water resistant motor for it. Check out Boat bilge compartment fans. Ebay has lots of them. Most are small blowers though.

You posted this as if you have already installed one, If you have can you post a pic for us to see.

Also wondering how noisy that would make the cab?
