Because it likes a place to expand and contract
Yes, an expansion tank can be hooked up to a hot water line. This is commonly done in the case of hot water home heating systems.
The purpose of an expansion tank in a hot water heater system is to accommodate the expansion of water as it heats up, preventing pressure buildup and potential damage to the system.

To allow for the expansion of heated thot water
The recommended pressure for a hot water expansion tank is typically between 40 to 60 psi (pounds per square inch).
The purpose of a hot water expansion tank in a residential plumbing system is to accommodate the expansion of water when it is heated, preventing pressure buildup and potential damage to the plumbing system.
A hot water heater needs an expansion tank to accommodate the increase in water volume that occurs when water is heated, preventing pressure buildup and potential damage to the system.
Many hot water heating systems with radiators need an expansion tank to operate efficiently. The fact you are in Concord NH is irrelevant.
The purpose of a hot water tank expansion tank is to absorb excess pressure and volume of water that occurs when water heats up and expands in a closed system. This helps prevent damage to the hot water tank and plumbing system, maintaining efficiency and safety by reducing the risk of leaks, bursts, and other issues.
Its a thermal expansion tank to absorb the pressure when the cold water heats in a hot water tank.
The necessary steps for hot water heater expansion tank installation are as follows: Turn off the power and water supply to the water heater. Drain the water from the water heater. Locate the cold water supply line and install a tee fitting. Connect the expansion tank to the tee fitting. Secure the expansion tank in place. Turn the water supply back on and check for leaks. Turn the power back on and test the water heater.
An expansion tank is used in a water heating system to accommodate the expansion of water when it is heated, preventing pressure buildup and potential damage to the system. It should be installed on the hot side of the water heating system.
