Duplex Hot Water Tank - Long Service Life

When people talk about heat pump efficiency, they almost always focus on the heat pump unit itself and its published SCOP (Seasonal Coefficient of Performance) rating. Product brochures, energy labels and marketing materials all highlight the heat pump’s laboratory-tested efficiency figures, creating the impression that the compressor alone determines how much a system will cost to run.
But real-world field monitoring across thousands of European and Australian installations tells a different story: the storage tank has a surprisingly large impact on actual system efficiency — and on your monthly energy bill over 15+ years of operation. A heat pump system is only as efficient as its weakest component, and for far too many installations, the tank is that weak link.
A cheap, poorly insulated tank with an undersized, low-efficiency heat exchanger can easily knock 10–15% off the system’s overall SCOP, turning a premium high-efficiency heat pump into a mediocre performer. The reverse is also true: a well-engineered stainless steel tank can help a heat pump deliver far closer to its laboratory-rated efficiency, saving thousands in energy costs over its full service life. The difference is not in the compressor — it is in how the tank stores, transfers and preserves the heat that the compressor produces.
In this article, we break down six specific ways that a properly designed stainless steel storage tank improves real-world heat pump efficiency, reduces running costs and preserves system performance for decades.

Australia is accelerating its transition toward more energy-efficient homes and renewable heating solutions.

Among the initiatives supporting this transformation, the Victorian Energy Upgrades (VEU) program has become an important driver for energy-saving technologies, especially in the residential hot water market.

As households and installers look for ways to reduce energy consumption and operating costs, heat pump hot water systems are gaining increasing attention.
