Do you have a single tank or two?...what are they made from?
How is the pressure maintained?
If I have your question correct you are asking if I have 1 or 2 hot water tanks
...I have only 1 and it is a 12 gal round unit similar to what you would have in your home only plumbed with aditional coils for warming by the engine cooling
We could keep it presurized all the time but we do not just incase some thing springs a leak and we are on deck
..But every time we turn on the water
pump the whole system pressures up to 20 psi..It is plumbed in a branch style system just like most houses are and I even have a small accumulator to help with hammer and constant flow issues...much like a deep well system in a home would have...One of my intended upgrades will be to install pump control switches for the pump at the galley
sink and in each head
as now we have to go the the panel or if you forget yell at someone to turn on the pump if you forget.
...It only takes the pump about 6 or 7 seconds to pressure every thing up from a dead rest position say you have been gone from the boat a week.
We get hot water in about 30 to 45 min engine
running time and the water will go from cold to well into almost to hot for a shower
with out adding cold water from the mixing valve..I have not heated from shore power
or the gen set yet but @ only 120v and 1200 Watts it may take at least that long or longer to heat I dont know.
We have 180 gal water on board in three tanks
which are all individually valved but all connected to the one sure-flow pump...and with 4 women in my life I could use more..
but its a huge improvement from our old boat which only had 40...but then they are ALL teenagers now..
As far as what we do to get hot water to the shower head
..nothing ..we just collect that water to use for teeth washing
water or in the galley
dish rinsing or whatever...or dad goes first which if its hot and sticky I dont use hot water anyway..but we do make a parade with showers once we start everyone showers so it helps cut that down...and yes we can all get a very quick shower with one tank..ya just have to have the push stop shower heads and holler at the girls to not use a lot of soap in their hair...the rule
is the worst offender or water hog goes last next time...
I hope that helps.
