“An absolute pleasure to deal with.”
Thank you for all your assistance. Truly appreciate your support — hope we can do more business again soon.
“Great service and much appreciated.”
There has been plenty of hot water for showers, and the insulation on the unit is excellent. I’m very impressed with your follow-up service!
“A great investment.”
I purchased an Aquarian five years ago and it has been a great investment. My old indoor water heater failed, and the Aquarian heat pump system was the perfect solution. Installation was quick and efficient, and I never ran out of hot water — even with two bathrooms. The environmental benefits and reduced costs are an added bonus. Highly recommended.
“Simple to install, effortless to run.”
Our plumber found it simple to install. The unit just does its thing — we’ve never run out of hot water, and our bills are lower than before.
“Great customer service.”
Thanks so much — very much appreciated!
Waiheke High School — Solar Installation
Waiheke High School engaged Energy Alternatives after a competitive tender process. EA recommended a Solar Study, allowing us to compare proposals fairly and make an informed decision. The Board approved the project based on its financial and environmental benefits, and for the learning opportunities it would provide for students.
The installed system is a large 75kWp array with 200 panels. EA made installation straightforward, honoured their contract pricing, and provided ongoing support. We are very happy to recommend Dana and the Energy Alternatives team for their professionalism and commitment.
“A local company that truly wants to make a positive difference.”
“We’re very happy with it.”
The Aquarian unit has performed well — the casing has faded a little, but the system continues to work reliably. Next step is adding solar PV and batteries for load shifting.
“Paid for itself within a few years.”
After installing our Aquarian heat pump in 2015, our power bill dropped by $50 in the first month. For a two-person home, the system paid for itself quickly — larger households would save even more. Highly recommended.
“Saving $80–$100 per month.”
We are very happy with our new all-in-one Aquarian heat pump water system!
“Hot water and great service.”
The AQ275LE tank is running perfectly with strong hot water pressure. Lance was excellent to work with. Looking forward to stage two — solar installation next year.
“Excellent energy saver.”
We absolutely recommend the Aquarian heat pump water heater (AQ170L). It has reduced our power use by 15–20% and the whole family is happy.
