My wife and I are building a new house and we are going to have the
plumber install two hot water heaters both in our crawl space which is
spacious. One of the heaters will be under the kitchen and service
the kitchen and the adjoining utility room. The other heater will be
at the other end of the house under the master bath room and it will
also supply the guest bath room. My question is this. Can this be
plumbed in a way that will allow the two heaters to feed off each
other and thereby double the capacity of water available at each end?
I can understand how you could put two heaters side by side and
connect them in series and have all of the hot water serviced from the
2nd heater in the series. However, I can't figure out how you can
accomplish the same thing with two heaters that are located at each
end of a house.

They could be plumbed in parallel, rather than series.
Not a good arrangement IMHO. Unless you also install
a wasteful circulating loop(s), the cold water in the
line between the heaters will always be introduced
into the Hot supply for one end of the house or the
other.
