Cost-effective Home Heating

We provide luxurious, affordable, in-slab underfloor heating and hot-water heating to new build in Canterbury.

In-slab underfloor heating

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.

Water heating

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.
