If you place the hot water cylinder side-by-side - (do you mean standing
on the same platform with their bases at the same level?) - then the
hot-water cylinder will only fill to the level of the upper-surface of
the cold water tank. Water doesn't 'fall' up-hill.

Siphon?

Peter; your point is?

Water in a "siphon" does _not_ fall up-hill. Siphonic action only results in
fluid from a pipe being discharged at a lower level (height aka head) than
the source , The pipe may or may not take a path which 'goes' up hill (being
pushed by the differential (air) pressure between the source and discharge
points,,,, but the fluid will go only go 'down-hill'.

Perhaps you need to retake Siphons 101 along with Sarcasm 101.
