I thought the expansion tank indicated a closed system. If I was wrong, I apologize. For what it's worth, I have just over 4% additional capacity for expansion, calculated by gallons. The heating supply store locally was helpful, but online was where I found that answer. The standard sizing is based on Btus/hr, which won't work with pressurized storage.
Is it a closed system (which mine is and I love not having to check or add water, etc.). Did my previous boiler to tank explanation make sense?
