Superheat Limited



Superheat Limited is a manufacturer of hot water cylinders, buffer tanks and instant water heaters.  We make domestic and commercial hot water cylinders that can be used with a range of alternative heating options such as solar, hot water heat pump, gas/diesel boiler and direct electrical (element) heating.

We have supplied mains pressure water heating and storage for hospitals, motels/hotels, sports clubs, aged care, off-grid homes and any facility that utilises large quantities of hot water.  Superheat dairy hot water cylinders feature in dairy milking sheds throughout New Zealand and our marine hot water cylinders have been fitted to large and small vessels.

Our services include the design and manufacture of bespoke hot water solutions and we can supply customised solutions when standard hot water cylinders do not fit your requirements. 

All of our products are New Zealand made.
