Hydronic Heating System: discover affordable comfort with Warmth NZ

Using advanced hot water heat pump technology and the natural heat-retaining properties of concrete, our hydronic underfloor heating system ensures the lowest possible running costs for whole-home heating.

What exactly is hydronic underfloor heating and how does it work?

The process is simple with air-to-water heat pumps

During construction, pipes are installed within the foundation of your home before the concrete is poured. Once construction is complete, water is circulated through these pipes and heated by an air-to-water heat pump system. This advanced home heating solution efficiently transfers heat into the concrete, creating a natural thermal mass that delivers comfortable and consistent underfloor heating. It's an ideal way of warming your house—especially during chilly South Island winters—offering both energy efficiency and year-round comfort for Kiwi homes.

The result is a warm, comfortable and energy-efficient home.
