Key Features

The SP series features the Australian designed Envelope solar collector, offering the latest in styling and all weather durability, and with five patents pending has been designed to meet or exceed Australian and International Standards in areas of strength and durability.

The SP Series features Solahart’s revolutionary multi-flow collector to extract the maximum amount of energy from the sun. This is used to heat the Hartgard fluid in the collector which rises into the heat exchanger where the heat is transferred to the water inside of the tank. The ceramic lined tank has a protective anode and the SP Free Heat series features additional protection.

The tank is equipped with an electric booster, alternatively an in-line gas booster is available.

How Roof Top Solar Systems Work

Solar Operation

The 302SP solar system has its vitreous enamel lined solar storage tank installed on the roof directly coupled to the solar collectors. In the Closed Circuit Series, heat is absorbed by the collector and passed to the ‘Hartgard’ heat transfer liquid inside the collector. As the temperature of the ‘Hartgard’ increases, the hot fluid rises up through the collector by the Natural Thermosiphon Principle, into the heat exchanger jacket around the potable water storage tank. Here, the heat is transferred to the potable water, cooling the ‘Hartgard’ fluid. The cooler fluid is then forced back down into the collectors through the displacement action of further hot fluid rising up into the heat exchanger jacket.
