Pretoria Residential House Project


  • This client wanted to save electricity by installing solar water heating on the residence
  • There are 4 family members living here as well as a nanny and gardener residing on site.
  • Due to limited option to install the solar water heaters and long distances from the application a ring-main was installed here to ensure hot water on demand.


  • 2x300litre solar geysers should supply enough hot water for usage as well as energy losses in the ring main.
  • The roof is flat.
