Rinnai, as an integral part of its H3 initiative, has designed and produced an electrical option in hot water storage units for commercial applications. The Infinit-E range is fitted with 1 and 6 titanium elements ensuring a productive and sustained product life cycle. The Infinit-E range is available from 12kw to 72kw making all models suited towards a variety of applications in all commercial and larger residential settings.

All electric cylinder models in the Infint-E range are manufactured with stainless steel providing added durability. Inclusion of stainless steel in the production process results in a lightweight model that can be easily transported and handled, excusing the need for heavy manual labour.

Maximum weight of an empty Infinit-E model is 54kg. Quality manufacturing and design ensures that all Infinit-E models are durable and robust, minimal maintenance working lives supported by extensive and comprehensive warranties.

All electrical elements can be fitted to a single-phase or three-phase supply should site limitations demand. Each contained element within the appliance range has its own controllable thermostat with a temperature range between 49 and 90 degrees Celsius.

Fuse protection is applied to all elements eliminating the requirement for expensive sacrificial anodes due to the inclusion of stainless steel within the manufacturing process.
