Have a closer look inside the demo HOT WATER CYLINDER of one of our heat pump hot water systems. To show the quality, durability, and simplicity behind every Calitec system.

All Calitec split systems are built using robust stainless steel casing, combined with high-quality components and materials.

The inner cylinder is made from high-grade 2205 duplex stainless steel, offering strong corrosion resistance. We use polyurethane insulation for optimal efficiency and heat retention.

In this video, filmed at a tradeshow, you can see the heat exchanger coil, the emergency back-up heater, as well as the magnesium anode, which helps protect the system from rust and corrosion over time.

Built to perform. Built to last.

Looking at the real cost of hot water over time?

Upfront cost is only part of the story. When you compare systems over 10 years, the total cost of running your hot water becomes much more important.

As this data shows, heat pump hot water systems stand out with significantly lower running costs, making them one of the most cost-effective options in the long run.

At Calitec, we see more Kiwi households making the switch for exactly this reason: lower energy bills, better efficiency, and long-term savings.

Thinking long-term? Heat pump water heating a smart move.
