    Description

    What Is Thermal Expansion?
    With modern plumbing codes mandating backflow prevention, thermal expansion can cause pressure buildup in domestic water systems. With the installation of a backflow preventer, check valve or pressure reducing valve on the supply line, the water heater and the system piping form a closed plumbing system under pressure. As the water is heated, thermal expansion occurs. Pressure increases until the relief valve opens and the expanded water "spills" from the water heater. This "spillage" results in wasted BTU's and shortened water heater life.
    The WiseWater Expansion Tank is designed to eliminate this problem by providing control of maximum pressures at a level below the relief valve setting. It also provides an additional space in the system to accommodate the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded.
    About the products:
    WiseWater Thermal Expansion Tank with a replaceable membrane. This pump is ideal for every modern installation and can be applied to any type of pump. The real volume of the pressure vessel is much greater then normal tanks of the same dimension. A compressor is not necessary since an air cushion, separated from the water by the membrane, maintains a constant pressure in the tank. These tanks can also be provided with stainless steel flanges.
    These tanks suitable for water booster system, pumps, potable water storage
    , domestic hot water systems.
    Expansion Tank on Potable Water Home and Commercial application.
