Expansion - HVAC Tanks. W essels manufactures three expansion tank designs: Compression, Bladder and Diaphragm.Each tank style has models that are either ASME or Non-ASME coded. Tanks range in size from 2 to 10,000 gallons. Most of Wessels pressure vessels are designed using a pre-pressurized vessel with an internal bladder or diaphragm to manage fluids under pressure.
An expansion tank has two parts which are divided by a rubber diaphragm. The top portion of the tank is connected to the hot water system and is filled with water. The bottom portion is filled with air set at approximately 12 psi. As the hot water system is turned on or off, pressure increases.
In older hot water heating boiler expansion tanks that do not have an internal bladder to keep air and water separate, over time air in the expansion tank may become absorbed into the heating water. Air may also find its way via the heating water to other air bleeders or vents in the system.
Hot Water Boiler Expansion Tanks - There are two types of expansion tanks used on hot water boiler systems. The steel expansion tank and the bladder type expansion tank. These expansion tanks are used to provide a cushion for the expansion of water when it is heated.

Sizing expansion tanks for water heaters can be a complex engineering challenge, but residential expansion tank sizing has been simplified through the use of calculators. New or larger expansion tanks may be needed due to pressure reducing valves, check valves and backflow preventers added to the community's water system.
Sizing expansion tanks. Hot water heater expansion tanks are small, but there available in several sizes. There are two important considerations to make when sizing an expansion tank; the incoming or supply water pressure and the volume of the storage tank.

A properly sized Expansion Tank eliminates these problems, by giving water a place to go when thermal expansion occurs.When a water heating cycle ends, or when any fixture is opened within the system, the impact of thermal expansion is reduced, and water drains out of the expansion tank …
