    Overview

    Engineered for high-demand commercial environments, the Rinnai HD28e (External) delivers powerful, uninterrupted hot water with exceptional energy efficiency. Purpose-built to thrive in Australia's demanding conditions, this external heavy-duty continuous flow system exemplifies Japanese craftsmanship, blending durability with intelligent design. It features an advanced heat exchange bypass system that ensures optimal water temperature without compromising on pressure—a crucial advantage in commercial settings requiring consistent output.

    Ideal for cafe's, salons, laundromats, and other small businesses, the HD28e offers an impressive 48kW output and delivers up to 37 litres per minute, making it capable of supporting multiple outlets simultaneously. Its sleek, compact build allows easy installation in outdoor spaces while offering anti-frost protection down to -20°C for year-round reliability.

    With a 6.0 Star energy efficiency rating, this unit only consumes gas during operation, translating into reduced energy usage and lower emissions. The built-in status operation monitor keeps users informed of system performance and water temperature at a glance. Compatible with Rinnai’s Manifold Electronic Control System (MECs), the HD28e can also be integrated into more complex hot water configurations.

    Whether for hospitality, retail, or care facilities, the HD28e offers a smart, efficient solution that keeps pace with your business’s needs—delivering peak performance with every use.
