If filling a hot water hydronic system serving a two-story building with a boiler on the lowest level of the building, the expansion tank must be sized to limit the pressure increase to ensure the relief valve is not used except in an emergency situation.
Because of this, the boiler is generally placed immediately upstream of the expansion tank, which controls system pressure and is the point where pressure remains relatively constant.
We don't believe the makeup water/ expansion tank should be connected to the cross-tie loop (the loop facilitating the use of any pump to serve any chiller).
