Envirosun HP Plus Heat Pump

There are not a lot of reviews for this heat pump and we knew this due to our extensive research prior to purchasing. In the end, we decided to go with the recommendation of the installer and relied on their good reputation that this heat pump would be suitable. It is not suitable for our needs despite the fact that it should do what we need it to… Read more

when we need it to do so. We are a family of 2 adults and 2 young children. Generally, the adults shower in the morning and the kids shower in the evening. When the install was complete we were handed the details to download the app and adapt the heat pump settings to suit our family. We need the heat pump to heat during the day when electricity is both cheapest and solar is highest 9am-4pm, and then a top up heat is required overnight. We programmed the heat pump to come on at 1am-5am so that we are using the off peak electricity rates and guarantee a morning hot shower. We programmed the heat pump to do exactly that. For the most part this worked HOWEVER, it did not work consistently and you should not have to check the water temperature before every shower. Some mornings there would be no hot water and some evenings there would be no hot water. We called the installer and after a $254 visit (this is within 6 weeks of install) they told us that because I had set the timer to "random times" this was not considered a heat pump fault. They reset the heat pump to eco mode and that was that. Eco mode means the heat pump is heating during the day which is of course ideal until you have 2 showers happening at 5-7pm. We need that 2nd overnight top up heat cycle. So i reset the time to suit our needs as it suggests we should do in the instructions. Again, it worked for the most part but would randomly not reheat. Having received the bill for the first visit I was very reluctant to be charged again and the installer recommended I speak directly with the Envirosun company. We spoke to a man at the company and he was really helpful in troubleshooting what was going on and totally understood why we need the 2 heating cycles. None of his troubleshooting or suggestions fixed the problem and our own troubleshooting determined that power cuts no matter how short, were interrupting the settings so a reset was required each time we have a power cut. We now know that power cuts require a reset however the problem continued even without power cuts. 20 degree showers at 630am and 28degree showers at 5pm. The heat pump is now set to AUTO which means it inevitably ends up heating during peak hour in the mornings and evenings. After extensive research, this is EXACTLY what i wanted to avoid. The AUTO function of course means that we have hot water but it is not taking advantage of the warmer midday times and that becomes a big problem in winter when we are trying to reduce our electricity bill. Absolutely would not recommend this heat pump at all. We were going to go for the top of the range but just could not justify the cost as is was more than double what we paid for this heat pump. Sadly, you absolutely get what you paid for on this model and we would not suggest going down this route. The 3rd party app is not great and gives no heat pump performance data, just the water temperature. We would go back to instant gas hot water in a heart beat and the cost savings for water heating are just not there. This was not a good decision in retrospect and we are extremely disappointed. We live in Adelaide.

The unit has been installed for a week. The hot water is flowing and fills my wife's bath. The unit is a lot quieter then the previous heat pump, which is unexpected bonus. Show details
