Hot Water Requirements

21 guest suites with a hot water load of 2,400L over a 1 hour peak demand period. The Southern Ocean Lodge is 80% powered by two Cummins M11 diesel Gen Sets and 20% PV solar and an efficient means of hot water generation was required.

  • 1 x Rheem 613315 Commercial Electric water heater as back up
  • 1 x Rheem 613315 Commercial gas water heater on LPG to handle ring main losses.
