Why do some hot water heaters need thermal expansion tanks and others do not?
I believe that the larger the hot water tank, the greater is the need for an expansion tank. Water expands as it is heated. This is why all hydronic heating systems require an expansion tank. A water heater would need expansion tank when a backflow preventer or check valve is installed in domestic cold water line directly after water meter. Some areas require backflow prevention, but not all. Have to check with local plumbing authority about that.

Does a water heater require an expansion tank?
In some cases, a water heater may require an expansion tank to help regulate pressure and prevent damage to the system.
How do you hook up two water heaters in line?
you want your cold line coming tying into both inlets on the water heaters and the hot lines tied onto the outlet side of the water heaters evenly (so they get even draw and one water heater doesen't have to work harder tnan the other). your recirc line coming in ties into the cold line in beetween the two water heaters with a circ pump going twards the cold line and the other end of the circ line tying into the hot line on the furthest fixture. on the cold line coming in you need a ball valve, check valve and expansion tank before it ties into any of the heaters. NOTE: The solution above is for tanks in parallel not in series.

Lowes, Home Depot and many Sears sell water heaters. You can also get them from plumbing supply shops.
