Mark,
Thanks, excellent info! Sounds like you installed yours about how/where I would do mine.
Reading about the features of the more sophisticated Wallases, they do sound like great units, but... I question whether I need one of them, wonderful or not. I'm used to heating with a wood stove, so with the fire cranking if you get too hot... move away or open the door

Sounds like I could just keep those habits with the 1300.
The one thing I could see the "better" Wallases having the advantage in would be running a duct to the v-berth. I don't like it warm for sleeping, so that's not a factor, but I can imagine where i might be nice for circulating air/heat and drying things out up there. But..... I have fans.
So all in all, and since I don't always boat in a heating climate, the 1300 is sounding really appealing. And the "real world" info for our boats is great.
On my "plus" list for the Wallas is being able to, essentially, stockpile heat. With propane, I would be limited to only the amount of fuel I could carry in tanks in the dedicated locker (which, even if I modify the locker is only probably two 10# tanks at best), and it's not always that easy to refill propane tanks underway. With the Wallas, if I were doing a long/cold trip (say the Inside Passage or similar), I could "stock up" on extra gallons of Kleen Heat for that one time and carry them aboard. Likewise when not actively using the heater, I would only have to carry the small, "built in" tank and not give up my port lazarette (which I always had earmarked for a future propane locker, but which now of course I've started using for all manner of things and would really miss).
Course like anything on a boat, it's always a matter of balancing the inevitable compromises - sure glad it's fun
