What is a bladder expansion tank? - AskingLot

A bladder expansion tank is a system which is used for heating and cooling purposes by absorbing the expansion force.It uses compressed air to adjust with the pressure changes by eliminating or accepting the water volume changes as it expands or contracts due to heating and cooling.Why expansion tanks need to be understood ContractorThe first expansion tanks on the old gravity systems were nothing more than copper-lined,open-top tanks located above the highest part of the heating system.As the water expanded,it filled the tank in the attic with the expanding fluid.If the tank overflowed because of excessive fill,the excess water spilled into the gutter of the attic.
