Pros

  • Among the cheapest R290 units with a published COP above 4.8
  • Pro series carries a 7-year tank warranty, 8 if you register it
  • Two magnesium anodes on the Pro tank
  • Widely stocked, so quotes are easy to compare
  • Runs on the heat pump alone down to -7C

Cons

  • Manufacturing location is not published
  • Not on the Solar Victoria locally made list, so it earns the lower Victorian rebate tier
  • The Select series drops to a 5-year tank and 2-year labour warranty
  • Emerald quotes 39 to 40 dB from 3 metres on its web pages while the data sheets show 49 to 50 dB at 1 metre, so compare it with other brands at 1 metre

Emerald hot water heat pump FAQ

How much is a Emerald hot water heat pump installed in 2026?

A Emerald hot water heat pump costs $2,750 - $3,750 fully installed in Australia before rebates. The cheapest model (Emerald All-In-One Pro 220L, 220L) starts at $2,750; the largest (Emerald All-In-One Pro 320L, 320L) tops out around $3,750. After stacking federal STCs (worth $640-$640 depending on the model and your climate zone) and state-based rebates, most households pay $710-$2,610 out of pocket.

Is Emerald a good heat pump brand?

Emerald Energy is an Australian company that has sold hot water heat pumps here since 2006, and its All-In-One range is now one of the most widely stocked propane (R290) units in the country. The Pro series is the flagship: an enamel tank with two magnesium anodes, a published coefficient of performance between 4.8 and 5.2, and operation down to -7C on the heat pump alone. The Select series sits below it on both efficiency and warranty. Emerald describes itself as Australian and does not publish where the units are built. Emerald is best suited to households wanting a high published efficiency and a long tank warranty without paying split-system prices.

What rebates can I claim on a Emerald heat pump?

Every Emerald model attracts federal Small-scale Technology Certificates (STCs) worth $640-$640 at point of sale. On top of STCs, Victorian households can stack the Solar Victoria Hot Water Rebate ($1,000-$1,400) and Victorian Energy Upgrades discount ($500-$2,000) to reach up to $2,700 in rebates. NSW (Energy Savings Scheme), SA (REPS), and ACT (Sustainable Household Scheme) have their own state-level top-ups. Most of it is automatic: STCs, Victorian Energy Upgrades and the NSW Energy Savings Scheme are already inside the price your installer quotes. Solar Victoria's rebate is the one worth going after on top, and your installer drives it. They lodge it with your quote, you add ID and proof of income, and it comes off your invoice on approval.

What is the warranty on a Emerald heat pump?

Emerald backs its tanks with a 7-year warranty and the compressor with 5 years. Workmanship cover for the install itself comes from your installer separately and should be at least 12 months. Warranty claims require the system to have been installed by a licensed plumber and serviced according to the manual.

How efficient is a Emerald heat pump?

The Emerald All-In-One Pro 220L runs at COP 4.9 (every 1 kWh of electricity input produces 4.9 kWh of heat output). Annual running cost is around $242 for a 2-3 person household, compared to roughly $700/year for gas storage and $900/year for old-school electric resistive storage.

How long does a Emerald heat pump last?

Modern hot water heat pumps last 12-15 years on average in Australian conditions. Tank life depends on water hardness (sacrificial anode replacement every 5 years extends life). Compressor life is the limiting factor and typically matches or exceeds the warranty period when the unit is correctly sized and serviced.

Emerald vs other brands: which should I pick?

Emerald sits at the budget end of the Australian market. It strikes a balance between quality and price. See the side-by-side comparisons below for direct head-to-head specs.

How loud is an Emerald heat pump really?

Emerald's data sheets rate the All-In-One Pro at 49 dB(A) and the Select at 50 dB(A), both measured one metre from the unit. The 39 to 40 dB figures on Emerald's web pages are measured from three metres, which is a different test. Sound falls with distance, so both can be true at once. When you compare brands, check the distance each figure was measured at, because most makers publish a one metre figure.
