How Does the Whole-Home System Work?

In a new build, a network of pipes is laid within the concrete foundation. An air-to-water heat pump heats water, which is circulated through these pipes—turning your floor slab into a giant, low-temperature radiator. This provides gentle, even warmth from the ground up.

The same heat pump also can deliver high-pressure hot water for your taps and showers, efficiently supplying your home’s daily needs.

A balanced ventilation system runs quietly in the background, bringing in fresh filtered air and extracting stale air-while recovering heat to reduce energy loss. It helps manage moisture, reduce pollutants, and maintain a healthier indoor environment.

Together, these systems work cohesively, each complementing the others, to create a low-maintenance, energy-efficient home with consistent warmth, fresh air, and reliable hot water.

Helping kiwi families to optimally heat their whole home with set-and-forget comfort

In this system, a heat pump heats water that flows through pipes in your concrete foundation—turning it into a gentle, giant radiator—while a balanced ventilation system keeps fresh air circulating throughout your home.

The result is set-and-forget comfort with exceptionally low running costs—steady warmth from the floor and fresh, filtered air in every room.
