o Split SWH

Storage tank inside not on top of the roof
 
Split systems use a pump and controller to circulate water between your geyser (tucked inside your roof) and the manifold directly coupled above the collector bank of Evacuated tubes.
From an aesthetic perspective estates, clusters and townhouse complexes often insist that residents install split systems like the one shown here.

Advantages:
  • more aesthetically pleasing to some
  • they often have slightly higher heat outputs than indirect close-coupled systems
  • Lighter load on roof
Disdavantages:
  • have mechanical and electronic componentry to circulate, rather than relying on natural convection and available watersupply pressure
  • no additional hot water storage capacity
