Heatwell - Underfloor Heating Experts
Electric underfloor heating, designed for New Zealand homes.
Heatwell has over 20 years' experience in the heating industry. We design our own range of underfloor heating cable and thermostats — built for New Zealand conditions and compliant with New Zealand regulations. We're not reselling someone else's product.
We Install
Professional installation across greater Auckland, from Rodney to Franklin.
Tiny homes, townhouses, lifestyle blocks, apartment complexes, retirement villages — new builds and renovations. We've been doing this since 2000.
We install using the Heatwell Best Practice system, developed over two decades to protect the cable during the build. It's why our installations withstand regular foot traffic and heavy furniture, and it's why we're able to guarantee our installation work for up to 25 years.*
Heatwell specialises in electric underfloor heating. We do not install in-concrete or water-based systems.
All we need to quote is your floor plan or the square meters.
* Our installation guarantee covers our workmanship. The cable carries its own manufacturer's warranty.
We Replace
Underfloor heating stopped working? It's usually the thermostat.
Controllers fail over time, the way any electrical appliance does. The cable underneath is almost always fine.
Our thermostats are designed to replace most pre-existing thermostats in New Zealand — including Siemens, Aube, Honeywell, and Warmup. In most cases we can use your existing floor probe and the same wall mount, so there's no lifting your floor and no new holes in your wall.
In Auckland? We'll replace it for you.
Outside Auckland? Buy the thermostat and any registered electrician can fit it. We'll talk them through it if they need a hand.
We Sell
Underfloor heating cable and thermostats, delivered NZ-wide.
Whether you're a professional installer or doing it yourself, we sell everything individually or as a complete kit — cable, thermostat, floor probes, tape and adhesive.
Two cable ranges: Pro Series is a twin core cable, Gold Series is the traditional single core cable. NZ Supplier Declaration of Conformity available for both.

Benefits of Underfloor Heating
Absolutely Quiet
Radiant underfloor heating operates in silence. No noise is generated from running underfloor heating. Nor is there light pollution. It's the perfect solution for those who are sensitive.
Radiant
Heat
Unlike most other forms of heating, underfloor heating warms the entire floor, allowing heat to rise evenly throughout the space. This method is significantly more efficient than traditional air heating systems.
Takes Very Little Space
Underfloor heating seamlessly integrates into your home, adding only 4-5mm to your floor height. There's no need for additional wall or floor space, and no outside unit is required.
Great for Allergies
Underfloor heating provides radiant heat, with no air being blown around. This means no dust, pollen, or other pollutants are circulated, creating a cleaner and healthier environment.
Pets LOVE Heated Floors
Transform your entire floor into a pet-loving heater! Add something soft, and you might even keep your furry friends off the furniture.
Cost
Effective
100W of power consumption is equivalent to an old-style lightbulb. Under one square meter of tiles, only 150W is required. Underfloor heating is more affordable than many people think.
