Hello tiny house wannabes! Westin posted a simple question which requires a complex answer.
Hope these may be useful:
http://www.resilience.org/stories/2016-03-18/ultimate-tiny-house-design
which describes two gravity feed thermosiphoning systems, one system which uses separate tanks (one for hot water to the taps and the other for thermal mass heating) and the other system shares one common hot water tank.
the above is a follow up article to
http://www.resilience.org/stories/2016-02-16/plumbing-the-tiny-house
which describes the manner by which water is pumped from the rainwater tank to the header tank and thereafter distributed to the taps and hot water cylinder.
the reason the blueprints don't match between the two articles is because this is a design still in evolution.
