Watts 0067371 Water Expansion Tank PLT-12

The Watts 0067371 Water Expansion Tank PLT-12 is an essential part for closed hydronic heating systems. This allows additional water volume within the entire system as the fluid warms up with the addition of a space in the structure. Water is the commodities, when it is heated, its volume increases. Lacking an expansion tank, this expansion can cause high pressures within the system and this can lead to leakage, bursting of pipes or even total failure of the system. The tank stores this high volume of water while ensuring that the operating pressures in the system are kept safe.
