Metlund Hot Shot Thermal Expansion Tanks
Without a Dual Port Thermal Expansion Tank a closed hot water system will quickly over-pressurize resulting in added stress to the various system components. Problems include: safety valves can fail or wear out quickly, wasted BTUs, and shortened water heater life.
Metlund expansion tanks are self cleaning and designed for the protection of potable hot water systems and as a reservoir to buffer "cold water sandwich" effects from tankless hot water heaters. The water is contained in a food grade polypropylene reservoir separating the expanded water from the air cushion which acts as a water hammer arrestor.
