Project Type: Solar Power | Ducted Heat Pump | Hot Water Heat Pump | Gas Conversion
Customer: Sam Clayton | Location: Petone, Lower Hutt | Property Type: Residential
⚡️ The Challenge
Sam’s home was previously reliant on gas for heating, cooking and hot water, with an old fireplace and a traditional electric hot water system. The goal? A warm, efficient, and fully electric home with lower energy bills and a reduced carbon footprint. But like many customers, the upfront cost and long-term return on investment were a big consideration.
💡 The Solution
Lite Energy designed and installed a full-stack energy system to achieve energy independence and year-round comfort:
Rinnai 14kW Ducted Heat Pump System – Whole-home climate control for heating and cooling
Rinnai HydraHeat Hot Water Heat Pump – Efficient hot water heating with ultra-low energy draw
14kW 32 Panel Solar PV System – Matched with 10kW inverting capacity and;
16kWh Battery Storage – For peak-time backup and energy independence
💸 Financial Breakdown
Before Installation:
- Winter Bills: $350–$450 (gas & electricity)
Summer Bills: $200–$300
Installation Costs:
- Heat Pump + HWHP: $31,500
Solar + Battery: $34,000
After Installation:
- Summer months: $200–$400 credit
Winter months: Not yet measured, but net-zero power bills expected
Estimated Monthly Savings: $300–$500
Solar ROI: ~5 years with an annualised ROI around 20%
“The HWHP’s low power use pairs beautifully with our battery system, meaning we can run everything without draining solar gains from earlier in the day.”
🔧 Installation Challenges
With a tight ceiling cavity that would have made even a seasoned caver nervous and a switchboard at the opposite end of the house from the inverter location, this install wasn’t straightforward. Our team navigated tricky duct routes and long cable runs, completing the install with zero compromises on performance or aesthetics.

Smart control via app for ease of use
Summer power bills turned into energy credits
Significant improvement in sustainability, cost reductions and household carbon reduction
