At a Glance: Emerald Energy All-in-One Solar Choice Heat Pumps Score Card
$$ Price
Efficiency:
- Emerald Energy disclosed a coefficient of performance (COP) of 4.6 to 4.9 for their all-in-one heat pumps in standard mode. This is at testing conditions of 20ºC and heating water from 15ºC to 55ºC. We estimate COP ranges based on a 20°C ambient water temperature, an inlet water temp of 15°C and target output temperature of 60°C. Thus this scores 4 out of 5 points for efficiency.
Warranty Offer
- Emerald Energy’s all-in-one unit offers a warranty of 5 years on tank for parts and 2 years labour. They offer 2 year parts and labour warranty for the heat pump components and electronics. This is notably shorter than many of the heat pump options on the market for labour and for the heat pump components. Score: 2 points.
Customer Reviews
- The average customer review score for the Emerald Energy all in one heat pumps is 4.7, with the main issue seemingly with the wifi/app setup. Most reviews indicate a high level of customer satisfaction. This scores 5 points based on real user experiences.
Functionality
- Emerald Energy heat pumps are equipped with features like Wi-Fi control, optional built-in electric heater,and a low Global Warming Potential (GWP) refrigerant (R290). There is no LCD, and the heating element is 1.6 kW and not 1.5kW. Additionally, the standard noise level is relatively high at 49 dB. As a result of these features, it scores 3 points for functionality.

Emerald Energy All-In-One Systems
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.

Pros and Cons of Emerald Energy Heat Pumps
Pros
- High Efficiency: The heat pumps have a high COP ranging from 4.6 to 4.9 , making them highly efficient in converting electricity into heat.
- Range of Tank Sizes: With a 220L, 270L and a 320L option the Emerald Energy heat pumps come in sizes to suit all residential applications. Many heat pumps don’t have an option with a 300L+ tank.
- Environmentally Friendly: Uses R290 refrigerant with a low Global Warming Potential (GWP) of 3.
Cons
- Noise Level: With a normal rating of 49DB and an option to decrease this to 45DB in ‘silent mode’ which heats water at a slower rate, the unit is one of the noisier options on the market. Best to keep this away from entertaining areas and open windows.
- Shorter Warranty: The warranty is shorter than competitors for the heat pump and electrical components and for labour on the tank.

Reviews from Australians who have installed Emerald Energy Heat Pumps
Very good so far and easy to control via phone app.
Works really well. The app provides lots of useful information. The size recommended is more than adequate for our family.
Happy with system
The system looks modern and neat.
I purchased this one cos it was the largest affordable one l could get - 320l with the electric backup. Even though l am single l do have a 4 bedroom house and wanted to future proof myself in case l get more guests staying with me. The unit looks really nice and modern unlike those round ones. I had the installer set to its max of 60degrees and the tempering valve opened (or is it closed) to maximize hot water output to house. The water is nice and HOT!! Only had it for less than a day. So it early to tell. The install was finished by 3pm and was left on boost mode till evening. l had a really nice hot shower by 9pm. It was warmer than l thought. I actually had to turn on the cold water to temper down the hot water. My only and biggest gripe is that the App connection to the unit dropped out within a few hours into the evening and wouldn't reconnect. All day today it keeps stating that it is low on "hot water" After Speaking with Chris, it seems to be a regular issue with this brand - losing wifi connection. So now l need to go outside and set up a timer on the unit itself to operate between 10am to 3pm Kind of defeats the purpose of having and promoting an app - that doesn't work. Its 2024, it should work of the bat. Lost 1 star for that
