We wanted a quiet, vented, use no power furnace
. in 1996 I found a used one of these units and installed it in my fiberglass Toyota/Chinook motorhome. Some people call these HYDAR FLAME furnaces a "POT type furnace".
I have been updating my 1970 Campster
with a new floor plan, LEDs and re designing the micky mouse pop top. I will post photographs of the Furnace
I have attached a photo of the Installed HYDRA FLAME.
