Closed-Circuit Technology: Built for Extremes

Unlike standard systems, the SP Series utilises a “closed-circuit” design. Instead of heating your household water directly in the collectors, it heats a specialised Hartgard fluid. This fluid then circulates through a heat exchanger to transfer its energy to your water.

This indirect process is a game-changer for regional properties, as it protects the system from freezing in winter and prevents mineral build-up in areas with hard or harsh water. Combined with our world-class Envelope collectors, the SP Series extracts the maximum amount of energy from the sun while remaining shielded from the elements.

Product Benefits at a Glance

  • Frost & Harsh Water Protection: The closed-circuit design and Hartgard heat-transfer fluid act as a “shield,” preventing the system from freezing or suffering damage from poor water quality.
  • Revolutionary Envelope Collectors: Features Australian designed and manufactured collectors with multi-flow technology to extract the maximum amount of solar energy even on cooler days.
  • Durable Ceramic Lined Tank: The roof-mounted storage tank is ceramic-lined and includes a protective sacrificial anode to improve the life of the system.
  • Significant Energy Reductions: Harness the sun’s power to provide a major portion of your home’s hot water needs, drastically reducing your reliance on expensive grid electricity.

Frequently Asked Questions

What makes "Closed-Circuit" different?

It works like a car’s radiator. The solar fluid circulates in a loop to collect heat, which is then transferred to your water. This ensures your household water never enters the solar collectors, protecting them from frost and scale.

Does it have a backup for cloudy days?

Yes. Every SP system is equipped with an internal electric booster, or it can be paired with an in-line gas booster to ensure you have steaming hot water 24/7, regardless of the weather.

What rebates are available for the SP Series?

As a high-efficiency solar water heater, the SP Series is eligible for significant federal STCs and Solar Victoria rebates. Our local team handles the entire application process to ensure you get the best possible price.
