The decision where to locate the water heater(s) is only partially independent of the decision of a tanked vs. tankless water heater , or the choice ...
An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure.

Radiator reflector panels being installed behind a domestic radiator. A radiator reflector is a thin sheet or foil applied to the wall behind, and closely spaced from, a domestic heating radiator.
Microcirculation on the left: Heated water is rising into the pipe on top of the hot water tank, cooling off on the sides of the pipe and thence circulating back into the tank. Right: Circulation of hot water is inhibited by the loop in the pipe. Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters.
