FAQ:

Q: What does an expansion tank do on a water heater?

A: The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure. If water pressure gets to high it can damage valves in plumbing fixtures, joints in supply pipes and the water heater itself.

Q: What is the purpose of an expansion tank on a water heater?

A: A water heater expansion tank is another small tank that is attached to the water supply pipe of the water heater. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure.

Q: How long does it take a 50 gallon gas water heater to heat up?

A: A 50-gallon hot water heater with 5,500-watt elements set to 120 degrees takes about 1 hour and 20 minutes to heat water coming in to the unit at 60 degrees. Conversely, when the water entering this same tank is 40 degrees, it takes 1 hours, 47 minutes to heat it up.

Q: Is a water heater expansion tank really needed?

A: An expansion tank is required if your plumbing system is closed i.e the block flow between the house and main water supply is blocked. Since there is no way for the pressure to go, it can put a lot of stress on your water heater and thus you end up needing an expansion tank for your water heater.
