About Superheat

For over 25 years, Superheat Ltd has been manufacturing water heating solutions and equipment for businesses and homeowners all over New Zealand – providing hot water to domestic homes, commercial properties, dairy facilities and marine industries.

Based in Christchurch, Superheat is a Canterbury treasure when it comes to keeping your home or properties brimming with reliable hot water! Unfortunately, their original and historic factory in Ferry Road was one of the many casualties of the Christchurch earthquakes, but Superheat is a survival story of the fittest!

With no time to spare, and customers still needing hot water solutions, Superheat successfully made a new manufacturing home in a modern facility in Woolston instead. There, they are able to keep producing high-quality water heating solutions nationwide, supporting their local region and its rebuild by producing locally made, locally trusted hot water cylinders for its customers!


Helping to support Christchurch’s economy by continuing to serve the people was one of Superheat’s main drivers for keeping its home local, and its customers warm!

After 25 years of development of their products, Superheat has the hot water cylinder for every condition and every requirement!
