SUNZ active solar hot water heating systems eliminate maintenance and maximize efficiency. By pumping water from your hot water cylinder through the solar panels on your roof no energy is lost through heat exchangers.

SUNZ solar water heating systems were ranked as the top two performing units in an independent performance report for the EECA $1000 grant scheme, and can supply up to 90% of your hot water needs, reducing your annual electricity bills by as much as 35%! (Source EECA)

Based on the report findings, and calculated at today?s electricity prices (May 2013), for the hot water needs of a family of 4-5 people that equates to an annual saving of $789 per year.
