A single large tank would be most thermally efficient. Multiple 50 gallon tanks in series could be an option with solar thermal heating on both of them and a normal electrical tank operation in the poland transformer tank heat pump circulation system size
Circulation continues as long as usable energy is available. When the circulation pump stops, the collector fluid drains by gravity to a drain-back tank. If the system is pressurized, the tank also serves as an expansion tank when the system is operating; in this case, it must be protected with temperature and pressure relief valves.
