Unlike some of our competitors, Envirosun collectors are designed to meet stringent performance criteria – not a price point. In fact, the solar collectors are so energy efficient, that they are up to twice as energy efficient as some other collectors currently on the market. Each black chrome collector is copper to copper, providing much better heat transfer. The internal components are made entirely from black-chromed copper, which is encased in low iron glass and extruded Anodised Aluminium framing. All of this ensures that the system can stand up to everything that the Australian environment can throw at it, including coastal environments! And while mounted on our aluminium frame this will allow maintenance free hot water for years to come.
