Emerald All-in-One Pro Heat Pump

If I could give a zero I would!!! they don’t call back or even reply we have had the machine broken and won’t give us a day to repair ‍ not hot water no showers in a week and it pours out with water. Cheap Chinese crap beware do not purchase this product … only buy Australia made . Never ever again will I buy Chinese crap. Stick with brands you know and you can’t go wrong. Show details

I decided to replace my reliable instant gas hot water system with an Emerald 320L heat pump system to utilise the large solar system I just got installed. I used Australian Energy Upgrades to do the purchase and installation, which it appears that they got Trigger Group Plumbing to do the work. The installation was done last Tuesday and the job… Read more

looked fairly decent, but the installers let me know once they had completed the job that there was an E09 error that they could not fix, but they assured me that the installation was complete and that I would get a call back to organise what next. We got a call back from a plumber who told me someone was going to try and get out to my place on Wednesday but if they did not have enough time it would be Thursday for sure. They also told me that they are going to replace the PCB board which commonly fixes the issue. Cold showers for the household on Tuesday, the 21st of July, in the middle of winter. Wednesday came and went with no plumber coming, more cold showers. Plumber came on Thursday, he arrived at 6:45pm, replaced the PCB board and was done by around 8:15pm. Error E09 remained, the plumber told me that if it was not the PCB board it is likely the communication cable which is really hard to get to. He told me that someone would get back to me on Friday. Hats off to the plumber, appreciate the hard work and dedication, I think they worked for Avenue Plumbing and Drainage. More cold showers on Thursday. On Friday (today) we contacted AEU around 10am and they had no update and were getting in touch with Emerald. I sent another email asking for further details around lunch, which they replied to but more of nothing. My partner directly called Emerald around 3pm to try and get some details, which they said they were following up. We got a call back from the installers (not sure who as my partner chatted to them) around 4pm, they let us know that they were going to come out Monday and try and fix the communication cable, and if that repair fails they will have a backup unit that they will install. Friday, Saturday and Sunday, more cold showers. I do understand that unfortunate things happen and no one really wants them to happen. But I also don’t understand how they have no quality control of inventory coming from the factory floor. I would have thought a quick diagnoses test would reveal that this unit has an issue, saving the installers time and money to install a dud unit, and then all the extra time spent by everyone involved. I also find it hard to understand how there have been 2 business days this week where nothing has happened, surely it would be a great idea to look after a customer who got a unit dead on arrival. I am going to exercise my rights under sections 260 and 263 of the Australian Consumer Law, a non-functional unit upon installation where a PCB replacement has failed constitutes a major failure. Under section 263, the choice of the remedy sits with the consumer, and I am formally requesting a full replacement unit. Also under Australian Consumer Law a replacement product is legally treated as a brand-new purchase. Which automatically gets full statutory consumer rights on the new unit starting from the day it is installed. I hope this review helps other consumers and Emerald in the long term. I will add an update on Monday and let you know how it went. Thanks

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 ·  1

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

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
