Hot water is needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing).

  • Page 13: For Your Information

    As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water. The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the...
