thermosyphoning solid fuel circuit

[texasholden]

Generally you're told to follow the rule that all feeds must rise and all returns must fall to encourage thermosyphoning.

Is there any reason why you should deviate from this?

I'm thinking if there is only a small vertical distance between the flow /return connections on the stove, isn't there a chance the heated water will attempt to flow up the return - especially as there is more of the return pipework being directly heated through radiation from the stove?

When you want to discourage thermosyphoning!

No! Hot water rises within the heat collector and will continue to rise so long as there is somewhere to rise to.
From the place where it has risen to as it loses its heat it will always return to its starting point, whether this be down the same pipe that it came up or finds another way to return.
