I can't comment on the stoves, but I recently installed a 40D forced air furnace and it has worked flawlessly so far. I ran it continuously for a week, 24 hours a day during the recent cold weather and it kept the boat nice and warm. Scanmarine was very helpful and friendly when I called for assistance with the install and when I went in to their store they spent a great deal of time with me suggesting different ways of doing things. I was very impressed and I love the furnace.
