We provide luxurious, affordable, in-slab underfloor heating and hot-water heating to new build in Canterbury.
Powered by air-to-water heat pumps generating radiant heat, our systems are very cost-effective.
You’ll love in-slab underfloor heating because it:
1. Is more cost-effective than most other forms of heating due to running at lower temperatures.
2. Creates a luxurious thermal environment by producing radiant heat. You will experience no cold zones, and the system WILL NOT blow allergens and bacteria throughout your house.
3. The slab acts as a giant heat store, giving a long-term heat.
4. Is silent, and as it’s underfloor, it takes up no living space.
5. By combining solar PV energy with an air-to-water heat pump, you dramatically reduce your dependence on mains electricity, and you can save as much as $150 per month on electricity costs.
Heat pumps heat water up to three times more efficiently than conventional electric resistance water heaters. They are more efficient because they transfer heat from one area to another, rather than heat an area directly. Heat pumps are ideal for hot water cylinders, swimming pools and underfloor heating.
A heat pump works like a refrigerator in reverse. Free heat is extracted from the atmosphere at ambient temperature and then transferred efficiently to a water system via a heat exchanger. Depending on the ambient temperature, for 2 kW of electrical energy, you can usually expect up to 8kW of heat energy. In comparison, conventional electric resistance water heaters provide just 1:1 heat for each kW of energy used.

“We have used warmth.nz on a number occasions to provide hydronic underfloor heating solutions along with dual heat pumps and Hot Water Cylinders. Our clients have found them to be very professional providing a good service along with education on how the systems work. This element of the build is so crucial to the heating and performance of the home so having warmth.nz as a service provider adds further strength to our overall design and build offering.”
“We love our underfloor heating. It is very economical to use and gives the whole house a magnificent feeling of warmth and comfort. We have found it has become more efficient to run as the slab dries and we set the controls to take advantage of natural heating gains. The installation and service of the system was easy and the team were great to work with”. Winner 2017 World Architectural News Best Modern Method of Construction project award, designed by MC architectural Studio in Christchurch NZ.
“Underfloor heating is a simple and affordable way of heating a whole house and it costs less than I thought. We recently provided a system supplied and installed by warmth.nz, our clients inform me it works extremely well. The entire warmth.nz team was great to work with. From design to quote thru to installation and commissioning. We recommend all new home builders & owners should consider underfloor & using warmth.nz”
We used warmth.nz underfloor heating in NZ's 1st 10 Homestar rated home. This system and the way it was integrated into the design and utilising other complimentary technologies was the biggest breakthrough in energy efficiency we have experienced in any project. We have installed similar systems by warmth.nz in almost all our BBA designs since. It is a dual system for both hot water and underfloor heating with a super efficient hot water heat pump powered by PV solar panels. The floor slab is fully insulated and effectively acts like a battery as it provides storage of solar-generated thermal energy.
warmth.nz is a great team offering good quality product and excellent service. As an architect I can say that support in creating a unique solution for always unique design is very important. In architecture things are never a repeat solution and need to be designed specifically for requirements, however the experience in combination with theory is the necessary combination that warmth.nz is happily offering, sharing and this very much resonates with my personal believe in importance of sharing the knowledge and experience.
