Honeywell Expansion Tanks
Honeywell expansion tanks are responsible for absorbing hot water within closed heating systems. With the help of butyl diaphragms, they separate the air from the system water. When pre-pressurized, the tank maintains minimum pressure to allow fluids to circulate. Honeywell recommends installing their expansion tanks by screwing them into the 1/2 in. connection on the bottom of a Honeywell Air Eliminator or air purger.
