In most cases, the engineered expansion tank size will be smaller than the 10% of the water heater volume, but, for budgeting/planning purposes, this estimate will get you in the right ballpark. Regular Price: $122. One more thing to keep in mind when sizing your tank: as a rule of thumb, it should typically be 1/3 full when cold and about 1/2 full when hot. A waterlogged tank is an expansion tank that no longer has an air cushion large enough to allow all the expanded water from the system to enter the tank without exceeding the maximum system pressure. The additional cost and space will likely be small. Department of Energy and current edition of ASHRAE/IES 90. Calculate expansion loops 14. sure change is a function of the size of the tank and the change in fluid tempera-ture.
