How exactly does it work?

An air-to-water heat pump heats water, which is circulated through a network of plastic pipes laid in a home’s concrete slab foundation. These are joined together and controlled by a manifold placed inside the house. The overall temperature control is set by a thermostat placed in a neutral heat zone in the house.

Discover the Warmth.nz difference

Save money from day one

Warmth.nz’s Hydronic Underfloor Heating system literally amplifies energy. For every 1KW of power used, 4KW of warmth goes into your home. That means real savings, real fast: the money you save on heating is likely to be greater than the cost of installation on your mortgage.

Sublime, steady, all-over warmth

Unlike forced air, Warmth.nz’s hydronic heating system warms everything else in your home too: people, pets, furniture, walls, windows, even the toilet seat. It’s a quiet, enduring heat that feels more satisfying and keeps your home safer by helping to eliminate mould, condensation and draughts.

Year-round climate perfection

Make chilly winters a thing of the past with the comfort of low-cost, radiant warmth throughout your home all winter. Then, when you’re melting in the summer heat, simply flick a switch to reverse the process and your home will become as cool as a cucumber.

Better for the planet too

Thanks to highly energy-efficient air-to-water heat pump technology, the system is easy on fossil fuels and better for the environment. It’s no wonder architects chose Warmth.nz’s system for New Zealand’s first, second and third 10-green star rated homes.
