Why?
Let's do the math:
Say you have an efficient Oxygenics low flow showerhead. That puts out 1.5 gallons per minute. If you have a the showerhead that came standard with the travel trailer, then it probably is putting out 2.5 gallons per minute.
Oxygenics: 1.5 x 15 = 21 gallons used during a 15 minute shower.
Standard: 2.5 x 15 = 37 gallons used during a 15 minute shower.
So the hot water usage during a 15 minute shower would be:
Oxygenics: 21 x 0.75 = 15.75 gallons
Standard: 37 x 0.75 = 27.75 gallons
These are just my suggestions. You and your spouse are of course, free to shower how ever you want.
Just wanted to bump this thread because you put so much work into the math. :)
Original Poster: Can the 15 minute shower. Even if everything is working, you'll run out of hot water in 5 mins.
If you want to be in the shower for 15 minutes - turn off the water.
If you want to be in the shower for 15 mins, with hot water running - then buy a tankless water heater.
