Econergy Heat Pumps — Proven Innovation, Built for New Zealand
The Econergy heat pump was developed using patented technology introduced in 2008, enabling hot water to be delivered more reliably and efficiently to the top of a hot water cylinder. This precise control technology significantly improved performance and efficiency, setting Econergy apart from other heat pumps available at the time.
When Econergy was first introduced, most heat pump water heaters on the New Zealand market were imported systems designed for different climates—primarily Australia—and typically relied on combined outdoor heat pump and cylinder units. In contrast, the New Zealand-manufactured Econergy system was specifically engineered to suit local climatic conditions and could be installed with either indoor or outdoor hot water cylinders.
A key advantage of the Econergy heat pump is its ability to be retrofitted to existing hot water cylinders. This allows homeowners to benefit from substantially lower running costs without the added expense of replacing their cylinder. The compact, separate heat pump design also offers far greater installation flexibility, avoiding the space constraints associated with large, combined units.
In 2017, Hot Water Heat Pumps Ltd—an Auckland based manufacturer with over 40 years of experience in water heating heat pump design, manufacturing, and servicing—acquired the Econergy brand and its patented technology. Recognising the innovation and long-term potential of Econergy, we are committed to supporting the brand with our industry-leading service and continuing to refine and advance the technology for the future.
