The HD55i has a 125mm concentric flue which can be extended up to 15m, less 1m per 45° bend. As with the whole Rinnai range, the HD55i is ErP A-rated and is super low- NoX ready for the next phase of Eco Design.
Typical applications include major restaurant chains, industry offices, hotels – anywhere with a need for reliable supplies of hot water delivered economically at energy efficiency levels surpassing all building regulations and European standards.
The HD55i operates between 1-10 bar pressure, which is suitable for mains cold water supply and systems with booster pumps and reaches water temperatures of up to 85°C, making the HD55i suitable for secondary return systems.
The smart digital controller regulates to within +/- 1ºC without any variation of temperature even with additional outlets. All models have full electronic ignition with no pilot light and operate on demand only, consuming no gas when not in use. The Rinnai HD55i is a fully modulating 52.6kW unit that can also be installed in a manifold arrangement. This ensures that the system can and will meet any hot water demand at all peak times, no matter what the demand.
