We have an old AO Smith 40 gallon gas water heater which seems to have
some leakage issues.

We have been anticipating replacing it for some time now but I need
some advice.

There are five of us in the house (including my 15 year old daughter,
who takes very extended showers!)

The current unit seems to poop out after 2 or 3 showers and we will not
run the dishwasher or washing machine in anticipation of showering.

For a new unit, should we go with a larger unit (75 gallon) or are we
better off with a smaller 50 or 65 gallon with a faster recovery time?
What about the "instant," tankless water heaters?

What gives the best performance, balancing efficiency and hot water
availability?

Michael,

How do you heat your house? Have you looked into adding a unit to the
heating systme for heating your hot water? For instance, adding an
indirect water heater or booster tank? If your heating system is old
you may want to look at the overall picture of both heat and ho****er.
Also, you may want to consult your local heating contractor for
reccomendations.
