Upgrade Your Hot Water. Upgrade Your Home. Upgrade Your Efficiency.
Smarter Way to Heat Water: The 2in1 Upgrade for Kiwi Homes
Across Christchurch and the rest of Aotearoa, many homes are still running outdated systems that waste energy, take up valuable indoor space, and deliver poor performance.
Warmth NZ’s 2-in-1 Heat Pump Hot Water Cylinder is designed to solve these everyday frustrations with one smart, efficient, and future-proof solution.
1. Your Current Hot Water System Might Be Letting You Down
✔ Rising Energy Bills
Gas, LPG, diesel, and older electric systems use 3–4 times more energy than today’s heat pump technology. That means higher monthly bills and long-term inefficiency.
✔ Weak Showers & Inconsistent Pressure
Older systems often produce dribbly showers, fluctuating temperatures, and unreliable pressure.
✔ Space-Hungry, Indoor Cylinders
Many traditional systems require large indoor cupboards, reducing usable storage space, especially in modern homes where every square metre matters.
✔ High Carbon Footprint
Gas and diesel water heaters contribute heavily to household emissions. As sustainability becomes a priority for Kiwi families, these systems fall short.
✔ Reliability Issues & Outdated Technology
Older heaters are slow to warm, struggle in cool temperatures, and break down more frequently, making maintenance costly and inconvenient.
If these issues sound familiar, it’s time to consider a better way forward.
