Product Description

The Solahart BT series is a roof mounted, closed circuit system specifically designed to provide higher efficiency for use in low to medium solar gain areas. The higher efficiency with its selective coating blue spouted collector surface maximises the absorption of solar energy while the closed circuit design makes it suitable to frost prone climates.

The Solarhart Streamline is an open or a closed circuit system with roof mounted slimline collectors and a ground mounted storage tank. The system is equipped with an electric or a gas booster and controller which senses when boosting is required to ensure constant supply of hot water.

Solahart GreenGlo Series is the most predominant one for large solar applications. The GreenGlo cylinder is a mains pressure with multiple coils and is pre-configured to be plumbed into multiple heat sources, including solar, wet-back, electricity or gas. This allows flexibility of design and ease to upgrade, modify the system whenever desired. The GreenGlo tank has a mainring port, it is high temperature rated and come in nine sizes up to 1,000 litre.

Technical and Environmental Benefits

Depending on the location and the system installed, a SolarHart hot water system can potentially save up to 75% of your hot water bill and simultaneously reduces the amount of fossil fuel energy or electricity required to heat water. The performance figures can be used in the Energy Model for Green Star NZ projects and can assist in obtaining points. All insulation materials and anti-freeze products contained within the system have an Ozone Depleting potential of Zero in their manufacture and composition. The products are manufactured under ISO 9001 certified Quality management Systems. The products are compliant with AS/NZS 4234 and MEPS NZS 4692.1:2005. 5 to 10 year warranty depending on details of system installed. Using this product may assist in reducing energy demand in a building and can be factored into the Energy Modelling results for Green Star NZ projects.
