This weekend will be the big test of my Tankless HW heater in our '15 31FS. I have a full hookup site, so running the water to figure it out won't be a problem. There are tons of good "tricks" out there to get it to work (including on this thread), so I'm staying glass half full for now, and I've already set expectations with the DW to give me some time to figure it out
. I did run across this video (now 3 years old), of a service guy giving a
The interesting thing he says is that you never add cold water, but adjust the temp of the hot water by adjusting the pressure of the hot water. Higher pressure = Cooler, Lower pressure = Hotter. Makes sense, but not sure how practical that is. He also says that the heater gives a 40* rise in temp. I'll report back next week on my "test drive" of the system goes. Wish me luck!
