I need to replace my 50 Gal. gas water heater.
I've been living alone in a house and never run out of hot water. I
always take showers, never baths, and my overall hot water use is
exceptionally low.
I'm wondering about two things.
Would a 40 Gal. tank meet my needs and would I realize a noticeable
savings by going with a smaller tank?
BTW, I rent the tank.
Thanks!

You mean by a 40 gallon gas heater? Or a 40 gallon electric heater?
If comparing electric versus gas do a cost comparison of the two
fuels, for your area.

As long as it provides sufficient hot water each time you use it is
doubtful that you would save very much, if anything noticeabl;e by
installing a smaller tank.
the amount of heat lost from a well insulated tank/heater being very
small. Note:
Also the heat 'lost' from the heater helps, in winter anyway, to warm
the house!
Note. The difference in surface area of a 40 gallon compared to a 50
gallon tank will be approx. of the order of 22% (very roughly). So the
slight difference in loss of heat from the hot water inside a well
insulated tank to the ambient air temperature of whatever room in
which it is installed will be very slight!
My electric company says that my hot water costs, typically, less
than 20% of my total electricity bill. In my case as a single person
less than that. So even if that could be reduced by one quarter the
reduction in cost each month would hardly be significant. maybe 30
cents per day; at best?

Look another way. 30cents a day adds up to 30x30=9$ a month. It may not be
much, but it's a decent lunch a month when eating out, or 2 at many a fast
food place.

That's right. If I could save $9 a month and not notice any hot
water shortage, I'd go for it.

i doubt the savings will be that much, ands check the first hour
rating of the old and perspective new water heater. not all are the
same
