Fresh Water Tanks

[Bob Lawrence]

I mounted a propane Precision Temp tankless hot water heater in the
side of our coach. Its use of propane equates to 12,000btu per hour.
Since there are 92,000btus in a gallon on propane, we only fill our 5
(4)gallon external propane tank about every 6 weeks.
This gives us unlimited hot water. Limited only by your holding tanks.
My 15 minute showers (continuous)are great!!
It fits in the size of the 10 gallon Atwood tank.
I cut out the side of the bus and mounted it. See pics under photos.
This is our second one. The previous one was mounted in our 26ft GMC.
We now only use the electric as a backup. Haven't used it in 5 years,
tho.
