Something to think about, when water is heated it expands. So where dose that expanded water in the heater go when the faucets are closed?  This is where an water heater expansion tank comes into play.

The Components Of A Water Expansion Tank

  • Inlet water connection 
  • Sealed tank
  • Water chamber
  • Pressurized air chamber
  • Flexible diaphragm 
  • Air pressure valve 

So in simple terms the tank is made to have an enclosed sealed space of a few gallons approximate 2.5 that provides a safe place for expansion and contraction. This will relive any stress on the water heater and it’s heating elements. By reducing this stress with a water heater expansion tank, the life of your water heater is greatly increased.

50 Gallons Expands To 52 When Heated

If you are to take room temperature water at let’s say 72 degrees and heat it to 125 degrees. That heated water now ill will expand to 52 gallons putting extra pressure on your homes water system.
