With a high efficiency gas burner and a stainless steel tank, the Aquamax 390L Stainless Steel Natural Gas Hot Water Storage System is an impressive and safer hot water solution for the family home, backed by a ten year cylinder warranty.

Key Features
  • Boasting a five star energy rating, the Aquamax 390L Stainless Steel Natural Gas Hot Water Storage System offers superior energy savings when compared to lower rated gas hot water systems.
  • Designed for external/outdoor installation.
  • Built-in mixing valve with the option for a twin temperature delivery installation. This allows you to set up, for example; 65°C hot water in the kitchen and laundry while only providing a safer 50°C (or lower) water to bathrooms.
  • Capable of delivering 205L of 60°C water in the first hour and 185L per hour after that (based on ambient temperatures of 15°C).
  • Australian made for Australian conditions; this hot water storage system from Aquamax naturally protects itself from corrosion without the use of a heavy sacrificial anode.
