Expansion Tanks

An expansion tank is not a water heater by itself but it is an important asset to consider if you use a tank water heater. This device is attached to the main water heater to provide an outlet for pressure and water buildup.

The thing is that when the water is heater, it undergoes thermal expansion, which enlarges the volume of water thus increasing the pressure against the walls of the tank. With the expansion tank your water heater will have more space within the system and helps the pressure to circulate more evenly.
