The factual accuracy of this diagram or the file name is disputed.
Reason: This is a fabrication by an editor unfamiliar with plumbing.
  • Firstly, there needs to be a clarification that this is a hot water supply system, rather than space heating by hot water. The delivery is to handbasins, not radiators.
  • Secondly, rainwater harvesting and other grey water systems do not deliver water for immediate use, for health reasons. Once again, this editor is letting their enthusiasm for "green" alternatives overflow beyond practice, practicality and relevance to the topic the diagram is supposed to be illustrating.
  • Finally the issue for this "thermosyphon circulation" system: water delivery is done by simple pressure to an open tap, there's no circulation as such, there's certainly no need to drive this non-existent circulation by a thermosyphon. This diagram is just sheer flight of fantasy.
As a further point, a thermosyphon circulation system (surely the essential point of this drawing, else it has no purpose) relies on two thing: heating water low down, removing that heat higher up. Even for a system drawn like this with circulation and a low heater, we have to then assume heat loss in the upper reaches of the pipe. So this is a hot water delivery system that can only work if it lets the delivered water get cold on the way!
There are some hot water systems that circulate. They are rare and obscure - they don't do this for delivery, but to speed up the delivery of instant hot water. Any discussion of such a sophisticated system needs to be rather more sophisticated than shown here, in particular it needs to discuss the important issue of relative pipe sizes (this matters) and the crude boiler/storage tank drawn here is inappropriately crude.

Summary

Description
English: A schematic of a thermosiphon water distribution system, used for radiators. The radiators reduce the heat of the water causing a change in temperature which keeps the thermosyphon system working optimally. The schematic was based on an image found at http://www.chilipepperapp.com/images/siphon.gif, but was modified (original picture worked on water pressure aswell). Ideally, the water heater in the schematic would work on electricity.
