Does an expansion tank sound like the solution?


Yes, with the PRV installed you need an expansion tank.
I'd also recommend a check valve on the cold water inlet of the water
heater to eliminate the cold system as part of the expansion area and to
ensure there's no backflow from the heater into the cold system.
