Hot Water Tank Expansion Tank

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering.

Hot water tank expansion tank. It is used to absorb excess water pressure. When water is heated or a hot water faucet is turned off abruptly pressure builds from expanding water molecules. What are expansion tanks. It is designed to handle that excess water that builds up.

A hot water expansion tank is a small metal tank usually 2 5 gallons that s installed just downstream of the cold water inlet valve that feeds your residential water heater. A properly sized tank will accommodate the expansion of the system fluid during the heating or cooling cycle without allowing the system to exceed critical pressure limits. We offer a range of expansion tanks for potable and non potable applications. The expansion tank s purpose is to protect your house s hot water system from excessive pressure which can cause damage to fixtures your water heater lines and or fittings.

Temperature pressure relief valve and thermal expansion the temperature pressure relief valve is a safety feature designed to operate as an emergency relief control and not as a constant thermal expansion control. A hot water heater expansion tank is the cost effective solution to thermal expansion and high water pressure. The tank is partially filled with air whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion. Expansion tanks when water is heated it expands due to a phenomenon known as thermal expansion.

The expansion tank serves as a backup system to prevent overworking your plumbing. The hot water expansion tank is a two gallon tank that hangs off of your hot water system or your boiler. This ultimately protects it from damage. The excess water volume instead of causing too much pressure on the plumbing rushes into the expansion tank and lowers the pressure in the water heater to safer levels.

Since water expands when it is heated due to thermal expansion the water heater creates extra water volume every time it heats water. An expansion tank or expansion vessel is a small tank used to protect closed not open to atmospheric pressure water heating systems and domestic hot water systems from excessive pressure. Expansion tanks are required in a closed loop heating or chilled water hvac system to absorb the expanding fluid and limit the pressure within a heating or cooling system. Portable hot water heater thermal expansion pressure tank.
