Infinity Solo Light Commercial Hot Water Storage System

Infinity Solo Light Commercial Hot Water Storage System

Infinity Solo - Gas fired storage water heaters 

Rinnai has revolutionised the way hot water has been supplied ever since we launched the first fully electronically-controlled gas fired continuous flow hot water system. The infinity series always deliver a continual flow of hot water for our customers needs and has been hugely succesful.

The infinity series  of condensing and non condensing water heaters now has a extended line-up including the Infinity Solo gas fired storage water heater. In addition to the existing product range, designed to be the ideal hot water system for Light Commercial requirements, where services may limit the use of continuous flow hot water system.

Rinnai's Infinity Solo gas fired storage water heaters consist of a highly efficient Heavy Duty continuous flow water heater with a heavily insulated stainless steel storage cylinder. The combination of condensing continuous flow water heaters with a storage cylinder allows for short periods of peak hot water use.

The Infinity Solo can be used for not only the Direct to Outlet system, but also Secondary Return system that distribute the hot water around a building. Infinity Solo will deliver a constant output temperature of 60°C, satisfying requirements for the prevention of legionella.
