Rinnai Launches New Line of Smarter Heat Pump Water Heaters
The new generation of heat pump water heaters offers improved efficiency, simplified installation, and integrated Wi-Fi connectivity.
Rinnai has introduced its new REHPW series of electric water heaters, designed to provide hot water with significantly reduced energy consumption. These units utilise heat pump technology, which extracts heat from the surrounding air and transfers it into the water tank. This method is substantially more economical than relying on traditional electric heating elements.
Technological Improvements and Efficiency
The new series is available in three tank sizes: 50, 65, and 80 gallons (approximately 190, 245, and 300 litres). The models are highly energy-efficient, with the 50-gallon unit achieving a Uniform Energy Factor (UEF) of 3.75, while the larger capacities reach 4.0. The system includes 4.5 kW backup heating elements and a variable-speed fan designed to minimise noise during operation.
Users can now manage the units remotely via Wi-Fi. The updated Rinnai Central app allows owners to schedule operation times and adjust energy usage based on electricity tariffs. Furthermore, the new models support the CTA-2045 standard, enabling them to connect automatically to electrical grid management systems when required.
Installation Flexibility and Design
Rinnai has prioritised ease of installation. Water connection points are now located on both the top and side, providing installers with greater flexibility when connecting to existing plumbing. The air intake and exhaust systems are positioned on top of the tank, allowing the unit to be placed flush against a wall.
The design also features integrated handles for easier transport, and the air filter is side-accessible for simple cleaning. The 50 and 80-gallon models include a third temperature sensor, which increases the precision of the hot water supply. The system remains functional even when ambient temperatures drop to 3 degrees Celsius.
Why It Matters
Interest in energy-efficient technology is growing globally. While heat pump systems may require a higher initial investment compared to standard electric heaters, their long-term cost-effectiveness and smart features make them an attractive alternative. With a 10-year warranty on the tank and key components, the new Rinnai series offers a reliable solution for those looking to improve their home's energy efficiency.
