The Rinnai Heavy Duty Range are designed for commercial use with internal and external units available. These are continuous flow units that offer constant outlet temperature with thermal efficiency. The systems have a high thermal efficiency with star energy ratings of at least 5.9. This is due to the systems only using gas when they are in operation. The most popular model is the HD200e. HDC211 models uses condensing technology to heat the water. The condensing technology incorporates 2 state of the art heat exchangers to achieve the ideal heating value from each mega joule of either natural gas (NG) or propane. The HD250e is the largest model in the Heavy Duty Commercial range and is still highly efficient with a star energy rating on 5.9.

Models in this series include –

The purpose of this design is to allow for short periods of peak hot water use. Therefore achieving a greater amount of hot water at that time than each individual heater can produce on its own. Since it is based on short periods of peak hot water use, this commercial hot water system is best suited for situations when there is a predictable volume of hot water consumption. Consequently, this system is ideal for hotels, motels, apartment blocks, student accommodation, shower blocks, and commercial kitchens and laundries.

Benefits of this include –
  • Reduced installation and service cost due to:
    • multiple valves not being installed
    • service to one system compared to many units
  • Visual impact is better than having multiple valves
  • Compatible with Rinnai solar pre-heating systems
