    Abstract - (Show below) - (Hide below)

    Requirements for direct, double feed indirect and single feed indirect types of units having hot water storage capacities of between 65 litres and 180 litres.

    Scope - (Show below) - (Hide below)

    This British Standard specifies requirements for direct, double feed indirect and single feed indirect types of combination hot water storage units having hot water storage capacities in a series of ranges between 65 litres and 210 litres, in which, when water is drawn off from the hot water storage vessel, there is automatically:

    1. replacement of water withdrawn by that from a cold water feed cistern incorporated in the unit and adjacent to the hot water vessel; and
    2. controlled replacement of the water in the cold water feed cistern from the water supply by means of a float operated valve.

    NOTE The preferred hot water storage capacities are 85, 115, 130, 140, 150, 180 and 210 litres.
