Emerald All-in-One Pro Heat Pump

I was recently convinced to convert to heat pump technology as it would use less energy than my twin element 305litre Rheem system, which has been now proven to be correct. We purchased the Emerald system through Carbonsavers Melbourne because of the good reviews we saw on both Carbon Savers and Emerald on Product Review and other sites… Read more ·  1

highlighting the high quality of the product, the backup service and the standard of the installation. This too proved to be correct, starting with Ella from Carbon Savers who oversaw the purchase and planning and Martin also of Carbon Savers who ensured that the installation complied with all specifications. This was followed by the installation team of Brady and Ryan who were punctual, knowledgeable, efficient and obviously took pride in their work. Seventy minutes after their arrival the only obvious sign of their visit was a new 320 heap pump heating our water. Thank you team

I can't believe how efficient it is to run & provided us enough hot water all the time, no hot water fluctuation while using it Savings of a hundred dollar, than using gas water heating Show details

The unit work as it designed to do, very happy with it to date. The only negative I have is the unit should have a better designed with the cable location. Show details ·  1

It’s been a few weeks since I got my Emerald heat pump. From the first time dealing with Carbon Savers I was very impressed with the professionalism from start to finish. Everything went smoothly with the installation and there was no hidden extras as they did a very thorough quote. Very happy. Show details ·  1

It's a great unit. Works very well, it's quite when it's on. Temperature is good and so far haven't run out of hot water. Show details ·  1

I recently purchased the Emerald All‑in‑One Heat Pump 270L, and while the experience began with significant issues, it ended with a result I am very happy with. The company I originally paid for both the sale and installation — Australian Green Solution (AGS) at Springvale Office & Warehouse — failed to deliver a properly functioning system. The… Read more ·  1

tank was not operating correctly from the start, and instead of taking responsibility, AGS repeatedly delayed, avoided action, and shifted blame. As a customer, this was extremely disappointing. Fortunately, the Emerald team stepped in and took ownership of the situation. Their support was outstanding. They arranged for a troubleshooting technician to inspect the system, organised a replacement tank, and coordinated a proper re‑installation. Their communication, professionalism, and willingness to resolve the issue made all the difference. Now that the new tank is installed, the system works perfectly. It runs very quietly, heats water efficiently, and performs exactly as advertised. The mobile app is simple to use and provides helpful monitoring of water temperature and tank status. The Boost function is especially convenient — one tap in the app gives a fast heat‑up when needed. I am genuinely grateful for Emerald’s product warranty and the technical support they provided during a difficult time. Without their intervention, I would not have received the working product I paid for. Their commitment to customer care deserves recognition. Overall, the Emerald 270L heat pump is an excellent unit, and the Emerald team has proven they stand behind their product.

I am very happy with my Emerald hot water heat pump, which operates as expected and is very economical to run. The installation went smoothly and the installation team was very efficient and professional. After installation, I had some WiFi connectivity issues with the controller and contacted the Emerald customer service. Their response was very… Read more ·  1

prompt and a replacement controller was delivered within a couple of days after the initial call, my unit is now working fine.

The 220 ltr unit has excellent quick / direct hot water supply, no lag experienced. The functionality of the App needs improvement, could be more user friendly. Replaced an existing Gas hot water unit. Show details ·  1

Easy to operate and extremely efficient. Love the app lets me utilise my Solar Panels Show details ·  1

Slow recovery rate, app "smart actions" is confusing, why dont they just have a "sun out mode" which is peak solar times 10am-4pm. Could do with larger compressor and a faster recovery time. Show details ·  1

Keep getting High pressure e05 fault, installed in November 2025 and got fault as below 2026 Jan , Feb, Mar , April, May Every month running out of hot water, see attached proof Show details

Only had the heat pump for two months. I only have 2 people in the house but we often have family visiting from overseas, hence, getting the 320l model. First day after installation, I suspected it was already a bit slower than expected, took a total of 7 to 8 hours to heat up to 60 degrees. Specially it was in the middle of summer. I have setup… Read more

schedule it to turn on at 10am and off at 5pm to utilize solar. Then the next day, after 2 person worth of usage, the temperature dropped to 48 degrees. It took more than 3 hours to get it back 60 degrees. Not sure if this is normal. The performance isnt ideal but manageable. After about month, it starts to take the whole day to get back to 60 degrees. Three weeks ago, I need to keep it in boost mode to get to 60 degrees. Two weeks ago, I could barely get to 50 degrees with boost active the whole day and I only manage to let my wife having shower. I contacted my installer and he advised to contact Emerald directly. It was on a Friday after lunch when I sent email to Emerald. Didn't get feedback until Monday which is fine. So I called their support number provided by my installer. Staff was polite but response time isn't the best. Staff is difficult to reach and I specifically requested for a call back many many many times, only received email for updates. During troubleshooting, I was told to take a video of a list of diagnostic parameters (just a list of 36 numbers) and send to Emerald for investigation. As an engineer, I am interested in knowing what each parameters mean. Therefore, I asked for descriptions of the parameters but was told they are internal use only. After confirming it being a compressor fault under warranty, I have asked to see if there is a way for me to upgrade to the model with heating element so that there can be a second way to heat up water even if compressor is faulty again. I know it won't fix the problem, but at least I can have some warm water while waiting for repair. My request is rejected even if I offer to pay for price difference.... Which is very disappointing. I don't have too much faith in the product. I got the unit replaced within 7 days after initial contact, the installation was a bit of messy job, I need to level the soil around the unit after the installation. It took 5 hours to heat to 60 degrees this time. This is 3 hours faster than the first unit. This suggested to me that I have been living with a faulty unit for 2 months. Hence, I have been spending more than double amount of energy to keep it running. I have requested Emerald to have my warranty reset since it is unfair to waste 2 months of warranty on a faulty unit. Emerald has also rejected this request. Asking to talk to their manager now. No feedback yet. I have no confidence in the heat pump at this point in time and I don't know when it will fail again.

Furthermore, the Wi-Fi is by far the weakest comparing to everything else I got at home. The app is simple to use but very limited in functionality. it would be good if we can setup scheduler with more logical conditions. I.e. activating boost mode if temperature is below a certain point during a particular time of the day.

P.S. I didn't have shower for a total of 7 days and I was very frustrated the whole time. On the days waiting for a warranty replacement, the water couldn't get above 30 degrees regardless of boost mode or not.

Update: at first, they have rejected my request the restart of my warranty. After requesting to speak to a manager, they have agreed to restart the warranty, which I believe is the least they can do.

Looks smart, all-in-one design. Maintains the heat very well and only runs for a couple of hours each day to provide sufficiently for a large house. Only slight negative is the wifi connection isnt strong, possibly a weak antenna design, as several other friends have reported the same with their Emerald units. Show details ·  1
