Aroha Apartments

Stiebel Eltron has been at the forefront of energy-efficient hot water systems for years, and its partnership with Collins Plumbing has resulted in the successful implementation of an air source heat pump hot water plant system in the Aroha apartment complex in Auckland.

This innovative system provides energy-efficient hot water to all 117 apartments from a centralised point on the site, creating efficiencies in both space and power. By using three air source heat pumps with a total of 96 kilowatt output, the system is incredibly efficient, boasting a 300% better energy performance than a typical electrical hot water cylinder. This results in a third of the running costs of an electrical cylinder, making it an excellent choice for both the environment and your wallet. Furthermore, the centralised system eliminates the need for a hot water cupboard in each apartment, saving between half a square metre to one square metre of space per apartment, allowing for more efficient use of space.

But that's not all - the system is also compatible with solar PV. This means that you can save even more money on energy bills while reducing your carbon footprint even further. With the ability to integrate solar PV into the system, the payback period on the initial system cost is shorter than ever before, making it an excellent investment for any multi-residential development.

Stiebel Eltron has monitored the power costs of the first four Ockham multi-residential apartments they provided an air source heat pump hot water system for and found that hot water bills for a 50-70 sqm apartment with two to three people living in it are only about $11-13 per month. That's a fraction of what you'd pay for a typical hot water system, making it an excellent choice for anyone who wants to save money while still enjoying all the benefits of a reliable hot water system. With Collins Plumbing's installation and maintenance of the system, the Aroha apartment complex showcases the effectiveness of a centralised hot water plant system in multi-residential developments, offering a sustainable and cost-effective solution for developers and tenants alike.
