Installed outsite, the horizontal tank forms an integrated system with the flat plate collector. The fluid, which is hotter, hence lighter, in the collector than in the tank, naturally rises to the tank. This is the thermosiphon effect.
This system is integrated: the tank and the flat plate collector are fixed together on a bracket. Different configurations of brackets are available.
