Homemade workshop heater

[23putts]

Would someone please post pictures of a homemade heat exchange that could be used in a workshop. I have heard of people rigging a car radiator and sitting a box fan behind them to disperse the heat.

I will be heating a 300 square feet barn that is well insulated.

Any help would be appreciated.

You could just go with one of these. I am in the process of finishing building my garage and have decided to install one. All I have to do is install another pump and a run of water lines and voilla heat!
