Whangarei - Calitec Hot Water Systems: Leading the Charge in Energy Efficiency
==========================================================================
Calitec Hot Water Systems, an innovative Northland-based company, is making waves across Aotearoa with its high-performance, energy-efficient heat pump hot water systems for residential use. Our mission is to help New Zealanders save on energy bills while creating more sustainable homes.
Supporting Local Initiatives
----------------------------
We proudly support local sustainable initiatives. One such event is the upcoming Electrify Te Tai Tokerau on 13 August in Whangārei. This community event aims to educate Kiwi families on how to lower their energy bills while making sustainable choices. We believe that New Zealand’s goal of full electrification is both realistic and achievable.
“Everyone’s talking about solar and electric vehicles, and they’re great for energy saving,” says Peter Ras, manager of Calitec. “But many Kiwis don’t realise that water heating is one of the biggest energy users in their family home. Replacing an old electric or gas cylinder with a heat pump water heater can reduce water heating energy costs by up to 75%. It’s a perfect solution, especially for larger households. Even if your existing system still works well, it’s good to start your research beforehand. When it’s time for replacement, you’ll know the benefits of efficiency and can make smart, future-proof decisions.”
The Shift Towards Renewable Energy
-----------------------------------
The New Zealand Government is committed to a renewable energy future. They are strongly encouraging electrification and energy efficiency. Fossil fuels and natural gas are being phased out. With firm policies and incentives expected, heat pump water heating is rapidly climbing to the top of the national energy agenda.
Calitec has been selected as a supplier for EECA’s (Energy Efficiency and Conservation Authority) Heat Pump Water Heater Product Demonstration. This government-backed initiative monitors systems nationwide. This unique opportunity puts Calitec’s locally designed split system to the test in real Kiwi homes, across different climates and household types. Results are expected in 2026.
Quality and Local Design
------------------------
Calitec has become a recognised name in the industry. Established seven years ago, we are supported by a growing nationwide network of independent installers. We provide our own premium stainless steel split systems, designed specifically for New Zealand’s unique conditions. Unlike off-the-shelf imports, these systems are purpose-built for local climates and Kiwi homes, making them a smart long-term investment for homeowners.
The Future is Electric
----------------------
Calitec supports the upcoming Electrify Te Tai Tokerau event: The Future is Electric. This free community event will feature Mike Casey, the founder of New Zealand’s first fully electric, zero-emissions orchard. He will speak about our electric future and his own journey, inspiring others to take action.
Calitec will be on-site with an information table. We welcome the community to stop by, ask questions, and learn how switching to heat pump water heating can benefit both household budgets and the environment.
