Central Heating New Zealand were early pioneers of this technology in our country. Since 2007, we have been involved in more than 150 geothermal systems for residential and commercial projects. We continue to advocate these systems for discerning clients who value energy efficiency and the planet.
Horizontal ground exchangers are the most common for projects with plenty of space outside. Large trenches or pits are dug for pipework at approx. two metres deep. Vertical bores are used where space is more limited. Well water is another popular method used, especially in Canterbury and Southland. This can be seen in large projects in Christchurch City after the earthquakes that used aquifer water to heat and cool the buildings.
