You have to compile the .dll, not just placing the mod folder as it is on Github. I don't have the knowledge for that unfortunately...
EDIT: I compiled the .dll using Xamarin Studio, it works fine for me. I had some problems before with ductwork not working, but once I changed the mod load order and disabled some mods I don't use anymore, it fully works now. Here's the link: https://www.dropbox.com/s/jt81t9uxqcuu21b/RimWorld-RedistHeat-master.rar?dl=0 I hope it helps while the mod is officially updated.
