I have a Little Cod in the forepeak of my 33ft cutter. Installed a low power draw 12v fan that blows hot air back into the main saloon. Works well. Swivels and serves as a cooling fan during hot weather. Need to be sure don't create low pressure zone and draw CO from stove. B
I installed the lil cod in my formosa 51'. I took an SS double hot water coil from an antarctic and installed it in the lil cod also. I run water through the stove to three heater fans through out the boat. Water temps stay around 90 degrees. I have a 5" galvanized stove pipe wrapped around the 4" SS chimney pipe. The shroud is about 36" long and is ducted to one of the heater fans. Hot air from the pipe is blown threw the heater fan into a lower cabin......nice!
