On an indirect system, where should the connections be made for the hot and cold supplies to a shower mixer?

Explanation:
In an indirect system, the shower mixer needs two separate supplies: cold from the cold water storage cistern and hot from the hot water cylinder. The cold feed is stored and delivered by gravity, while the hot feed comes from a heated cylinder, allowing the mixer to blend to the desired temperature. This pairing keeps the cold supply independent of mains pressure and provides a reliable hot supply. Connecting both feeds to mains would be a direct mains setup, and using only the hot cylinder or only a mains cold feeder would not provide the proper indirect arrangement.
