Hot water heat pumps are the most efficient way to heat domestic hot water — using up to 70% less electricity than a traditional electric cylinder. They extract heat from the outside air and transfer it into your hot water tank, even on cold Wellington mornings.
Why this works
Up to 70% Lower Power Bills
Heat pump technology delivers 3–4kW of hot water heating for every 1kW of electricity used.
Lower Carbon Footprint
Less electricity used means lower emissions — a meaningful step toward a greener home.
Retrofit Compatible
Replaces most existing electric cylinders. We handle the swap-over end-to-end.
Works With Solar
Integrates beautifully with rooftop solar — store excess generation as hot water.
Smart Controls
Schedule heating windows around off-peak rates and household routines.
Long-Lasting
Modern systems are designed for 15+ years of reliable service.
Switching from an old electric cylinder to a hot water heat pump is one of the highest-return energy upgrades available. Contact us for a free assessment.

Most households save $300–$700 per year on hot water power bills, depending on usage and existing system.
Yes — modern hot water heat pumps operate efficiently down to -7°C or lower. Even on the coldest morning they'll outperform a resistive electric cylinder.
Often we replace the cylinder as part of the install for best efficiency, but some setups allow retrofitting around existing tanks. We'll assess on-site.
Subsidies and rebates change over time — we'll let you know what's currently available during the consultation.
