    Overview

    The Rheem Ultra 28L Internal Gas Continuous Flow Water Heater (Model 866B28) is a powerful and efficient solution for households with substantial hot water needs. Engineered for high-demand applications, it delivers an impressive 28 litres of hot water per minute, ensuring ample supply for large families or busy homes with multiple hot water outlets in use simultaneously. Designed with Rheem’s advanced technology, this model achieves a 6-star energy rating, which means it delivers on-demand heating while significantly reducing energy consumption, perfect for environmentally conscious users seeking efficient performance without compromising on capacity.

    Rheem’s smart electronic control system keeps water flow and burner operation precisely balanced, maintaining steady temperatures even with fluctuating water demand. The unit’s pre-set 50°C option removes the need for a separate tempering valve, streamlining installation and enhancing safety. Equipped with a frost protection system, this heater is safeguarded against damage in freezing conditions, making it suitable for colder climates as well. An integrated digital display provides real-time monitoring of water temperature and diagnostic data for easy servicing, while the Rheem Q Factor™ ensures water temperature consistency, even when multiple fixtures are demanding hot water simultaneously.

    Additional safety and efficiency features include the Flamesafe® overheat protection, which automatically shuts down the system if it reaches unsafe temperatures, and a low minimum flow rate of just 1.5 L/min, making it compatible with flow-regulated taps. Designed for internal installation and available with a natural gas configuration, this Rheem model combines reliable performance, cutting-edge technology, and the capacity to handle the highest household demands with ease.
