All of our commercial hot water cylinders are made in New Zealand to meet both New Zealand and Australian standards.

Commercial hot water cylinders

We provide many heating options for commercial hot water heating to fit your needs, including gas or diesel boilers, hot water heat pumps, solar water heating and electric elements.

With over 25 years in research and development, our commercial hot water systems are proven as both effective and energy efficient in the most demanding and high-use environments.

  • Mains pressure sizes from 33 to 800 litres capacity
  • Low pressure sizes from 10 to 800 litres capacity
  • We can include fittings of up to 5” (125mm) for mains pressure and 1½” (40mm) for low and medium pressure
  • We can include multiple fittings if several heat sources are used
  • Coils or multiple coils can be specified for any indirect heat source such as boilers, solar and hot water heat pumps
  • Hot water cylinders can be specified with a stainless steel outer case if there is a potentially corrosive environment or if the hot water cylinders are visible to the public

We are happy to provide advice regarding the size and layout of commercial hot water cylinders to ensure your needs are met.
