I have a 75 gal 140Kbtu water heater serving a 12-flat. It seems to be
enough. When it comes time to replace it, would it be wise to use three
40 gal 34Kbtu units? They're a lot cheaper and they'll fit in the space.
You're not even close. I used the free sizing software at Bradfordwhite.com
to determine that you will need approx 100 gallons of storage and, even more
important, 200,000 BTU input for a fast recovery.
I'm surprised that your tenants are not complaining with the minimal heater
that you have now.
If you're heating water for four apartments, go ahead and place a
separate water heater in each apartment and let your tenants pay to
heat their water.
Personally, I think I would size up one of those on-demand systems and
have the manufacturer size the thing for me. I've installed on-demand
systems in restaurants that need 180-degree water (and lots of it) for
their dishwashers. On-demand units are a great space-saver and they
also save energy (saves ya money). The lady who owns the restaurant
with the on-demand unit told me that her energy savings were
significant enough to pay for the unit and the installation costs in
less than three years.
