Provide Cost-Effective Home Energy Solutions

We provide luxurious, affordable, in-slab underfloor heating, cooling and heat pump hot water to new builds in the South Island of New Zealand

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:

1. It creates a luxurious thermal environment by producing radiant heat energy. The system will NOT create draughts throughout your home.
2. It is quietly transferring heat energy into every room continuously.
3. The slab acts as a gentle radiator, and it takes up minimal space.
4. It is the least expensive way to heat a whole home.

In-slab underfloor cooling

Being more aware of climate change, we are now offering the cooling system as well. The same heat pump and network of pipes can be used for cooling. You can enjoy a warm winter and a cool summer with warmth.nz underfloor system.

Underfloor cooling works in the same way as underfloor heating. The air-to-water heat pump will work in reverse in summer. The energy is taken out of the house via radiantly cooled floor surfaces. There are successful projects around the world. However, we are experimenting at this stage.

With Econx automation systems, we are offering the cooling function at no extra cost from our end, to collect data of our projects.

Heat pump hot water

Air-to-water heat pumps are ideal for domestic hot water heating, swimming pool heating. Compare to electrical water heaters, heat pump hot water is energy (cost) saving from day one.

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.

Power Up with Solar Panels

By combining solar PV energy with an air-to-water heat pump, the home is immediately turned into giant energy batteries by storing the heat energy in the cylinder and the concrete slab.

Solar energy is an effective way to maximise energy efficiency and minimise the running cost for residential houses. The underfloor system can connect to the PV panels, which are placed on the roof, to drive the heat pump all year round. The heat pump is turned on in the morning and off again late afternoon.

The domestic hot water system can also be powered up with solar panels, with very little investment. Solar panels are the perfect enhancement for the existing heat pump-driven system.
