We have a new build and I was going to purchase a hot water heat pump. I wasn’t aware of solar-electric hot water and stumbled upon this through a friend. The One Energy approach makes so much sense and I’m super pleased with how it performs. The guys have supported me with my queries from time to time and couldn’t be more pleased with my choice.

I had my 6 panels installed within 10 days of the order and the impact was immediate. I’m tracking the savings daily on my app and what I really like is the extra heat storage we get into our cylinder. Our tank now heats up to 72 degrees on the cloudless days and we’re loving the extra hot water

I didn’t realise what a drain hot water was on my power bill, until I looked into the One Energy approach. And now, I can’t believe I waited this long to get their system. It just works and I don’t even know it’s there working away for me. It has my recommendation.

Once I saw how much of our bill was just heating water, switching made sense. I’d looked at older systems, but they felt dated. The One Energy setup is modern, fully electronic, and easy to manage. The team were great to deal with — straight-up and helpful. Since installing, the app makes it simple to let solar do the heavy lifting, and the savings are clear. I’d highly recommend One Energy for smart tech and outstanding service.

Over the last eight months, we’ve clocked an average 33% decrease in our monthly kWh power usage. Seeing those numbers and the related cost drop while our comfort stays the same is a great feeling. A smart bit of kit installed by a One Energy team that takes genuine care and responds if there are any issues.

Our family loves taking long showers and so our electricity bills have always been high. Adding OneEnergy’s solar hot water heating has made a big difference to our power bills, especially in sunnier months. Installation was quick and simple, and the online dashboard clearly shows how and when we are saving money. Thanks, OneEnergy!
