¹ AEER: The Annualised Energy Efficiency Ratio (AEER) measures a cooling system’s efficiency by comparing its total cooling output to the electricity it consumes, including standby power.
² TCSPF: Temperature Compensated Seasonal Performance Factor (TCSPF) measures a heat pump’s seasonal heating efficiency, adjusted for varying outdoor temperatures.
³ ACOP: The Annual Coefficient of Performance (ACOP) measures a heater’s efficiency by comparing its total heating output to the electricity it consumes, including standby power.

² Self-Cleaning function requires manual activation.Tested by Intertek, Report No. 250626075GZU-007 and 250626075GZU-001, an independent third-party laboratory.
³ Based on independent laboratory testing under controlled conditions. Tested by China Quality Certification Centre (CQC), Report No. 2017-CH-08009. Actual performance may vary depending on environmental conditions.

#Based on internal laboratory testing of a 3.5kW unit in Cooling Turbo+ Mode, the average indoor temperature reduced from 36.10°C to 29.93°C within 10 minutes. Actual performance may vary depending on room size, layout, ambient conditions, and user behaviour.
##Check product specifications for details.
*For full warranty terms and conditions refer to the related warranty booklet.
**R32 refrigerant: is a highly energy-efficient, low Global Warming Potential (GWP) gas used in modern air conditioners. It offers better cooling performance while using less energy, making it ideal for eco-friendly air conditioning systems.
***GoldGuard: is 14-karat gold plating to provide enhanced corrosion resistance and durability.

NB: Reverse cycle air-conditioners are an effective solution as they provide both cooling and heating and are highly efficient. However, unlike gas heaters, their heating capacity will reduce with colder ambient temperatures, which is especially relevant for homes in colder areas. Discuss with your installer things like the local climate, the size of your house, its orientation and construction (such as glazing, doors, insulation), and your expectations, so a system with the appropriate capacity can be selected.

The product information on this website (comprising product brochures, warranty information, installation manuals, diagrams, specifications and representations) relates to current products. This information may be different for superseded products. For superseded products please contact Rinnai to confirm product information.
