At a Glance: Emerald Energy All-in-One EE-HWS-A1-270L

Scoring is based on our heat pump scorecard which is consistently applied to each brand and heat pump on the Australian market.

$ Price: The Emerald All-In-One heat pump is priced under $2,500, positioning it as one of the most cost-effective units available, especially when factoring in available rebates.

• Company Backing and Trustworthiness: Emerald has a physical office in Truganina, VIC and has been operating in Australia since 2006. The brand is also diversified beyond heat pumps, offering smart meters, EV chargers and air conditioning solutions. Based on our scoring system, Emerald receives 4 points in this category.
• Warranty Offer: Emerald provides a 5-year system warranty and 2 years labour and service coverage. While this warranty meets industry standards, it falls short of the extended tank or parts coverage offered by some competitors. We score this warranty offer 3 points.
• Customer Reviews: Based on verified reviews through Solar Choice’s independent platform, Emerald heat pumps have received very positive customer feedback including 25+ five-star reviews. This earns them 5 points.
• Functionality: Emerald includes Wi-Fi control, an LCD display, and 3 programmable on/off timer schedules. The heat output exceeds 10W per litre in all models, meeting our performance criteria. However, the units operate at 49 decibels in standard mode which is slightly louder than our <45 dBA benchmark. This earns them 4 points.

Emerald Energy – Company Background

Emerald has positioned itself as a heat pump leader in environmental abatement, with a vision to reduce greenhouse emissions through smart technology.

Emerald Energy Heat Pump Model and Ranges

Emerald Energy offers both all-in-one heat pump systems and split heat pump systems. This difference is whether the heat pump compressor is located above the tank or as part of a separate unit – read more here.

Deciding between these options is partly dependent on the preference of the appearance, and there are some key differences in the performance and capabilities of the units described below.

Emerald Energy Split Systems

The split systems come with a quite small tank option of 200 litres and a quite large tank of 300 litres. The 200L option will typically suit 2-3 person households, while the 300L option could cater to 5-6 persons.

Key Features of Split Systems:

• Energy-Efficient Design: Microchannel heat exchanger in the tank for improved efficiency.
• Optional Built-In Electric Heater: Available for faster heating and continuous hot water supply in cold weather.
• Blue Diamond Enamel Tank: Smooth material surface, reducing dust adhesion.
• Anti-Legionella Function: Provides automatic or manual disinfection modes.
• Split System Design: Allows the water tank to be placed close to the usage point, with the outdoor unit positioned away from living areas to minimise noise impact.

Emerald Energy All-In-One Systems

The all-in-one Emerald EE-HWS-A1 heat pumps come with a 220 litre or a 270 litre option. The 220 litre unit will typically cover 3-4 people while the larger 270 litre option can typically cater to 4-5 person households.

Emerald Energy All In One Heat Pump Key Features

• DC Inverter Technology: Inverter technology is more efficient at heating water than the alternative induction approach which is used by many other heat pumps on the market.
• Wi-Fi Enabled: The heat pump can be controlled and configured via the Emerald app.
• Eco-Friendly Refrigerant: Uses R290 (Propane) refrigerant with a low Global Warming Potential (GWP) of 3. This is much better than some cheaper models on the market which use R134A refrigerant with a GWP 1,430.
• Silent Mode: The normal operation of the heat pump is rated at 49DB making it one of the noisiest heat pumps on the market. They do feature a ‘silent model’ where the heat pump will heat water slower to reduce the sound. At a rating of 45DB it will remain far from silent.
• Modern Design: Compact and stylish design that fits into contemporary home environments.

How much do Emerald Energy All In One Heat Pumps Cost?

The retail price for Emerald heat pumps typically cost less than $2,500. Remember, this excludes shipping and installation costs.. Australian consumers may find that prices can fluctuate due to the brand changing product costs, installation requirements and additional functionality requirements.

Emerald Energy Heat Pump Warranty Terms

Emerald Energy’s warranty offer is notably shorter for both labour and the heat pump unit components when compared to other brands in the market. This may make the units less attractive for consumers seeking longer-term assurance and reliability. That said, customer reviews don’t show many issues with the warranty terms or maintenance but this should be considered when making your final purchase decision. 

All-In-One Systems:

• Tank Parts: 5 years
• Other System Parts: 5 years (includes the heat pump unit, compressor, control board/electronics, fan motor, and magnesium anode)

Split Systems:

• Tank Parts: 7 years
• Other System Parts: 5 years (includes the heat pump unit, compressor, control board/electronics, fan motor, and magnesium anode)

Labour Warranty:

• All Models: 2 years of labour warranty for both the tank and other system parts

Pros and Cons of Emerald All-In-One Heat Pump

Pros

• Affordable upfront cost
  Emerald’s models are priced under $2,500, making them one of the more budget-friendly heat pumps that still qualify for federal and state rebates.
• All-in-one design simplifies installation
  Because the tank and compressor are integrated into one unit, installation can be faster and less complex than split systems — especially where space or access is limited.
• Built-in Wi-Fi and LCD control
  All models come with smart control via the Emerald app, plus an on-unit LCD display. You can monitor or adjust the system remotely and set schedules.
• 3 programmable timers
  Offers flexibility to schedule heating around your solar output or off-peak tariffs — a useful feature not found in all budget systems.
• R290 refrigerant
  Uses a low-GWP refrigerant (GWP = 3), aligning with current environmental standards and future regulatory trends.
• Available in 220L, 270L, and 320L sizes
  Covers a wide range of household sizes (from 1–6+ people), with optional electric boosters for colder climates or higher demand.

Cons

• Above-average noise rating
  All models are rated at 49 dBA, which is higher than some quieter alternatives. This may be noticeable if installed near bedrooms, living areas, or windows.
• Mid-tier warranty coverage
  The system comes with 5 years warranty on parts and 2 years on labour. While standard, this is shorter than the 7–10 years offered by some premium brands, and no breakdown is provided for individual components like the compressor or tank.
• No split system available
  Buyers who prefer to separate the compressor and tank — often for indoor installation flexibility or quieter operation — won’t find that option in Emerald’s range.
• Lower heating performance in larger models
  Heating power per litre drops in the 320L unit (~8.4 W/L), which may mean slower recovery times compared to the smaller 220L and 270L models.
• Lack of extended component protection
  Unlike some competitors, Emerald doesn’t publish extended tank or compressor warranties, which may concern buyers looking for long-term assurance.

Are Emerald Energy All In One Heat Pumps Worth It?

As one of the more affordable heat pump water heaters on the Australian market, Emerald’s all-in-one models present a viable option for homeowners looking to reduce energy use without a large upfront cost. The inclusion of built-in Wi-Fi, smart scheduling, and compatibility with major rebate schemes adds to their practical value.

The main considerations for buyers relate to the system’s 49 dBA noise level — which may not suit every installation location — and the warranty coverage, which is standard (5 years on parts, 2 years on labour) but not among the longest in the market. Component-level warranty details are also not publicly broken out.

That said, Emerald has operated in Australia since 2006 and offers a range of energy-related products, indicating some business stability and experience in the sector. For many buyers, the balance of price, smart features, and rebate eligibility may make Emerald’s system a reasonable choice.
