The Best Water Heater Expansion Tanks

Is it really difficult to give a longer life to your water heater tank? To be honest, at my end it was until I came to know about the water heater expansion tanks for the tanked water heaters.

The problem with water heater with tank is that while heating, they put stress on the plumbing pipes. The mechanism works like:

  • When your heater is turned on and water starts heating, water expands due to thermal expansion.
  • Due to this extra volume of water is created.
  • For example, standard 50 gallon will expand to approximately 52 gallons and thus the extra 2 gallons puts pressure on plumbing pipes.

To solve these issues we have water heater expansion tanks at our disposal.
