Have a gas fired vertical tank hot water heater for the house. Relatively
Question: if wife takes one of her infinitely long showers, are these units
(typically) supposed to have the heating ability to keep the flowing water
at the set point temperature as the hot water flows out, and the new cold
water flows in ?
Or, must one typically just stop using water to give the tank a chance "to
catch up" ?
generally . no , they dont have the btu's necessary to keep up,
a long shower or several huge laundry loads , could deplete it , and catch up
time would be neccessary .
Tankless water heaters on the other hand , can keep up with demand as they are
designed for this ,
pros, you dont have 40 -50 gallons of water being kept hot all the time,
you always have alll the hot water you need ,
you will realize enrgy savings !!
cons , about twice the cost of normal tank water heaters
they need to be mounted on an outside wall . for purpose of venting

so you have a regular gas hot water tank, how many BTUs is it. they
vary from under 30 thousand to over 75 thousand BTUs. larger 75 gallon
tank with 75K BTU costs a bit more but is money well spent
while some crow about tankless they often introduce more troubles than
they solve. slow arrival of hot water upon turn on, unit must detect
water being used, turn on burner and get hot before you get any hot
water, no hot water in low flow like valve open just a little to wash
hands, cool hot water in areas where incoming water is cold in winter,
no hot water at all during power failures, need upgraded gas lines and
possibly flue for proper operation, and standby losses of regular tank
are really lost during heating season they help heat your home,
although during AC use they can add to the heat load some. plus the
energy you save will never exceed the higher initial cost of the
tankless, espically considering they need regular service.
normal tanks are very reliable and tend to not have technical troubles
till they leak.
so whats up with your install
Depends on the flow rate of the shower head. You can reach a point where it
will not keep up. Depends also on the water incoming temperature also. If
you have a Weltrol tank with water at 68 degrees, it will heat faster than
water from the ground at 50 or winter city water at 45. The good side is
that once she finds the maximum time she'll tend to take shorter showers and
save on both the water and gas bills.
