Save energy, reduce costs, and embrace sustainable heating without a full hot water cylinder replacement.
Upgrade your existing hot water cylinder and retrofit it with a hot water heat pump in NZ today.
Not sure if you need a straightforward fix, a smart upgrade, or a full replacement? Here’s how to tell which one fits your situation:
| Your situation | What's actually going on | The right move |
|---|---|---|
| Cylinder's stopped working properly | A specific fault, like a failed element or thermostat, but the tank itself is sound, mains pressure, and under 8 years old | This is a fix, but it's the moment to go for a hot water cylinder upgrade rather than repair like-for-like. You're already paying for someone to open the cylinder, so swap the old element for a heat pump instead of putting the same inefficient part back in |
| Cylinder's working fine, but the power bill remains high | No fault at all, tank's still sound, mains pressure, under 8 years old | This is a straight hot water cylinder upgrade. Retrofit a heat pump onto your existing tank for the running cost savings, no repair needed |
| Cylinder's old, low pressure, or the tank itself is damaged | Over 8 years old, low pressure, or showing rust or leaks in the tank itself | This calls for a full hot water cylinder replacement. There's no sound tank left to retrofit onto, so a new system is the only real option |
If you've landed in that last row, the right replacement is a proper hot water heat pump system rather than a like-for-like cylinder swap, either an integrated system or a split system, depending on your home's layout. And if you're still not sure which row you're even in, our guide on the 9 signs your hot water cylinder is ready to retire walks through exactly what to look for.
Typically, a retrofit system costs between $7,500 and $11,000, including GST. This is roughly the same as an integrated system, and can save you significant money compared to a full split system replacement.
That price gets you access to premium technology like Panasonic or Rinnai, without writing off a cylinder that's still doing its job. You're investing in the heating component itself while extending the life and value of infrastructure you've already paid for, rather than starting again from scratch.
And because running costs drop by up to 75%, the system pays for itself through lower monthly power bills over time.

Yes, with some caveats, your cylinder will need to be mains pressure and under 8 years old. If it qualifies, you get to keep your functional cylinder and simply swap the inefficient heating element for a heat pump, rather than replacing the whole system.
Most modern mains pressure tanks are suitable, making retrofitting a cost-effective alternative to a full system replacement, and reusing your current cylinder cuts waste while bringing it up to modern efficiency standards.
Yes, our systems use advanced R744 (CO₂) and R290 refrigerants. These are specifically proven for NZ winters and are engineered to perform in freezing temperatures without relying on expensive backup elements.
Unlike older models, these refrigerants allow the system to extract heat from the air even in sub-zero conditions. Panasonic’s CO₂ system performs reliably down to low ambient temperatures while remaining exceptionally quiet at 37dB. Rinnai HydraHeat Split is specifically designed for NZ outdoor conditions to ensure fast recovery and high efficiency during the coldest months.
