Customised hot water system with 2-25 Rinnai INFINITY commercial units electronically manifolded together, using the Rinnai MECS system (manifold electronic control system), on a freestanding skid with insulated pipework. Wall mount and back-to-back systems are also available.
This system can offer energy savings as there are no cylinder heat losses or pilot lights, and the system only uses gas when in operation. Demand Direct provides endless water for applications where there is peak demand for a set period of time.
Ideal for commercial applications where demand can be easily calculated by totaling the full flow from all outlets used, such as; shower blocks, restaurants, and food processing plants.
For commercial applications the water heating system must be sized and installed to written guidelines from Rinnai.
Hard or aggressive water will need to be treated in order to use this system, if in doubt please test before use.
Not suitable or approved as a pool heater.
398-11194 MJ/h (2-6 INFINITY units)

Standard factory preset is 75 °C. Units can be adjusted via DIP switch, to deliver 42, 55, 60, 70, 75 and 85 °C. Advise at the time of order, or if on site refer to the back of the installation manual for information on how to change. If using with storage backup the INFINITY units must be set to 75 °C.
Rinnai has two types of systems for larger domestic and commercial hot water applications. Our article will give an overview of the two systems and which one to choose for your application.
We’d like to reassure you that gas will continue to be part of New Zealand’s energy mix for years to come, even as we move towards carbon neutrality as a nation.Read Article
