Heat Pump Review: Is It Worth the Investment Emerald for Australian Homes?

 





At Solar National, we speak with Australian homeowners every week who are weighing up their hot water options. Heat pump hot water systems have moved from a niche product to a mainstream upgrade and the Emerald Energy heat pump is one of the brands that comes up in these conversations more than almost any other. So we decided to put together an honest, detailed look at what the Emerald range actually delivers, who it suits, and where it has room to improve. If you’re shopping for an energy-efficient hot water system and want real information rather than marketing speak, this Emerald heat pump review is for you.

Hot water can account for up to 30% of your household’s total electricity bill. With grid prices continuing to climb, switching to a heat pump hot water system is one of the highest-return efficiency upgrades an Australian homeowner can make. The Emerald heat pump hot water system sits in the mid-range of the market but does it deliver on its efficiency promises? Read on.

Who Is Emerald Energy?

Emerald Energy is an Australian-owned business that has been operating since 2006. While manufacturing takes place in China consistent with the vast majority of heat pump brands sold in Australia the systems are designed and engineered locally. Beyond hot water heat pumps, Emerald also sells air conditioning units and smart home energy technology, which speaks to their long-term commitment to the Australian energy efficiency market.

At Solar National, we consider brand longevity an important factor in the heat pump hot water space. A company that has traded in Australia for nearly two decades is far more likely to honour warranty claims and provide ongoing parts support than a brand that appeared in the last couple of years. On this measure, Emerald holds up well.

Emerald Heat Pump Models Available in Australia

The Emerald hot water range is split into two categories: all-in-one units and split systems. Both use R290 propane refrigerant and DC inverter technology, though the features differ between the two.

All-in-One Heat Pump (EE-HWS-A1 Series)

This is the model most commonly installed across Australia. The all-in-one design combines the heat pump and the tank into a single upright unit with a clean rectangular profile a step away from the bulky cylindrical shape most people associate with older hot water systems. Available tank sizes are:

  • 220 litres — recommended for households of 3 to 4 people
  • 270 litres — suitable for 4 to 5 person households
  • 320 litres — designed for larger families of 5 to 8 people

Each all-in-one model includes built-in Wi-Fi and can be managed via the Emerald smartphone app. An optional 1.6kW electric boost element is available across all sizes, which steps in automatically during periods of high demand or cold weather. The Solar National team installs all three sizes across metropolitan and regional areas, and in our experience, the 270L is the most popular choice for the average Australian family.
