🔥 Why OneEnergy.nz’s Solar Electric Hot Water System Is a Game-Changer for Kiwi Homes

At Green Heat, we’re always on the lookout for innovations that make sustainable living more practical, affordable, and impactful. That’s why we’re excited to spotlight OneEnergy.nz’s fully installed solar electric water heating system—a game-changer for Kiwi households to future-proof your home, ready to cut costs and carbon.

OneEnergy.nz offers one of the smartest energy upgrades available today: a fully installed solar electric hot water system that turns your existing hot water cylinder into a giant energy-saving battery.

💧 Hot Water Is the Hidden Energy Hog

Did you know that water heating can account for up to 50% of your household’s electricity use? That’s up to $1,500 a year for an average-sized home. OneEnergy.nz’s solution directly tackles this by using solar power to heat your water during the day—while topping up with mains electricity only when needed.

☀️ How It Works: Smart, Simple, and Seamless

OneEnergy.nz’s system is designed for maximum efficiency and minimal hassle:

• Solar PV panels feed energy directly into your existing hot water cylinder

• Sol.Flare Controller (built for NZ conditions) manages temperature and usage with smart scheduling (Manufactured in Europe and specifically adapted for New Zealand’s unique climate and energy needs.)

• WiFi-enabled monitoring lets you track performance from your phone or computer

• Grid-boosted backup ensures you always have hot water, even on cloudy days

• No plumbing, no pumps, no moving parts—just clean, quiet, zero- maintenance tech

📱 Real-Time Control, Real Savings

The Sol.Flare Controller doesn’t just automate your hot water—it puts you in control. You can:

• Set temperature targets

• Schedule heating to match free power hours from your retailer

• Monitor usage and savings instantly

This means smaller households can eliminate nearly all mains energy consumption for hot water, while larger households can dramatically reduce it.

🔄 Retrofit-Friendly and Expandable

Already have an electric hot water cylinder? Perfect. OneEnergy.nz’s system retrofits easily into most NZ homes. And if you’re thinking long-term, the system is expandable:

• Add more panels for winter performance

• Upgrade to a grid-tied system later

• Add batteries when prices drop

It’s a modular approach that grows with your needs.

📊 Proven Performance, Fast Payback

With a typical setup of 2.7kW (6 panels), households can expect a payback period of 4–5 years. And thanks to NZ’s solar conditions, even winter months deliver meaningful savings.

For those wanting more, the system can scale up to 10 panels—or transition into a full grid-tied setup with diverters and batteries.

🔄 Better Than Heat Pumps

Compared to heat pump water heaters, OneEnergy’s solar electric system wins on:

🧠 Why Focus on Hot Water?

OneEnergy.nz’s philosophy is simple: right-size your solar investment to maximise return. By using your hot water cylinder as a storage device, you avoid the pitfalls of selling excess solar back to the grid at low tariffs—and instead use every drop of energy you produce.
