Hot Water Boiler Expansion Tanks - HVAC Hydronics

The hot water heating system needs an expansion tank to work properly and maintain proper pressure. As the hydronic heating system heats the water in the loop, the water needs a cushion storage tank. That is for the increased pressure and volume of water. The system pressurizes, and the expansion of the water needs a place to go.
