Why Choose Kowhai Heat?

PERFECT FOR MULTI-STOREY BUILDINGS

A unique cable-based system (no pipes) minimises heat loss and offers a more cost-effective installation.

FLEXIBLE INSTALLATION

Install the solar panels at any distance from your hot water cylinder (HWC) for ultimate design freedom.

EXTREME DURABILITY | SIMPLE DESIGN

No moving parts like pumps means nothing to wear out or break. Built for long-term reliability.

LOW MAINTENANCE & NO UPGRADES

Forget routine servicing. It works with your HWC's standard existing elements—no costly replacements needed.

EASY & SAFE ROOF TOP INSTALLATION

Only lightweight panels go on the roof—NO heavy, bulky tanks to lift, secure, or maintain.

AUTOMATIC POWER CONTROL

The smart Kowhai Heat Controller manages power input—no need to manually cover panels in summer.

DUAL-POWER RELIABILITY | ALWAYS ON

Seamlessly operates between free solar power or utility power according to the timer settings.

COST-SAVING & GRID-SAFE

Eliminates the need for an expensive inverter. Crucially, it DOES NOT feed power back into the grid.
