Superheated Hot Water Boilers

Ici Caldaie have a proud 60 year history and the largest production plant for steel and industrial boilers in Europe, producing around 12,000 hot water boilers and 1000 industrial boilers per year. They are also a leader in the journey towards new forms of energy generation and cleaner technologies, with many collaborative projects working simultaneously on both sustainability and green energy, mostly linked to hydrogen as a fuel source.

They have a complete range of high efficiency superheated hot water boilers utilising the latest European designs for high efficiency and low emissions.

Supplied fully packaged and ready for installation, these boilers feature advanced energy saving controls, and are available with a management system certified to manage the safety chains and operate the boiler without supervision (unattended operation) for up 72 hours of continuous boiler operation.

The boilers are designed, manufactured and fully tested prior to delivery to a range of international standards including European Directive 2014/68/EU (PED), ASME, Lloyds Register, Rina, & TUV. They also meet, in full, the NZ standard requirements, namely the “Health and Safety in Employment Act 1992 – Approved Code of Practice for the Design, Safe Operation, Maintenance, and Servicing of Boilers” and the AS/NZS 3000 Electrical Wiring Rules.


High temperature hot water boilers for operating temperatures above 110°C and up to 12bar design pressure.
