    Single feed cylinders have an arrangement internally which provides the cold water feed and expansion for the Primary system. Advantage is it does away with the need for a separate Feed and Expansion cistern, but one major drawback, inhibitor cannot be added to the primary system in case it mixed with the secondary water.

    Google 'Single Feed' or Primatic' cylinders if you need more.
