I understand that but the rate your mentioning is when the hot water tap only is fully open. Actually the water may not even last that long. Depends on what your pump puts out, unless you use the city connection. I don't know what the gpm would be.
Off the top of my head I think my pump is 1.2 gpm or 1.5 gpm somewhere around there.
So let's go with the 1.5 gpm (easier numbers) if you turn the hot a 1/3 of a turn and the cold 2/3 of a turn your hot should last 12 mins. Now if you turn both the hot and cold down some more your hot water should last even longer.
Now before everyone jumps on the band-wagon and crucifixes me here this is not scientific, I only used what brain cells I have left, after which I will be having a nap.
Right or wrong and assuming everything else is working properly this theory of mine seems to work just fine for us two.
You get yourself a better shower head e.g. Oxygenics and do the Navy thing as a couple have mentioned your hot water should last quite a while 6 gal or 10gal.
