Apricus Apartment Solar Hot Water System

The Apricus Apartment Solar Hot Water System is a project specific, complete solar hot water system for multi-residential buildings and apartments.  Delivering sustainable, low energy, environmentally friendly hot water for residents with a centralised system.  Gain high Greenstar and Homestar points for NZGBC assessments.

The Apricus System provides guaranteed hot water, whatever the weather, using back-up energy sources when required. This system is compact enough to fit on the smallest of roofs, delivering a sustainable solution for an increasing building type.

  • Anodised aluminium frame — flat to roof or angled
  • Mounting system — for all roof materials
  • Live online monitoring, reporting, and integration with BMS
  • Complete system specification and design
  • Performance modelling using Polysun software
