They keep production of key components in-house at three of their own factories and 14 manufacturing affiliates under the Rinnai Group umbrella in Japan.

The basis for manufacturing and all aspects of the process at Rinnai is to think and act from a scientific perspective. They have built a market-orientated production system that combines policy management, the quality control cycle, and continuous improvement proposal activities, based on a bottom-up approach heavily influenced by the Toyota Production System, and utilizing Total Productive Maintenance and Total Quality Management.
