Rinnai | P Series 8.0kW Reverse Cycle Inverter Split System | GoldGuard Coated
The Rinnai HSNRP80B is an 8.0kW reverse cycle inverter split system rated for rooms up to 53m² (2.6m insulated ceiling), delivering heating and cooling via a wall-mounted indoor unit with Wi-Fi and voice control. The HSNRP80B features Rinnai's GoldGuard nano-coated condenser coil, which resists oxidation and corrosion in coastal and harsh environments. It complies with AS/NZS 3823 and operates on 220–240V 50Hz household power with a 25A recommended circuit breaker.
Australians buying a split system face a choice between noise levels, refrigerant leakage risk (piping runs to outdoors), and energy efficiency across sizes and brands. The HSNRP80B addresses these needs with a compact 8.0kW capacity, Wi-Fi remote app control for flexible scheduling, and an inverter compressor that maintains a consistent room temperature without cycling on and off, cutting energy bills on moderate-load days. The reversible cycle suits Australia's seasonal climate swings from cool winters to hot summers, and the GoldGuard coating provides durability in salty or humid air, particularly on the coast or in tropical regions.
Trade installers and homeowners value the HSNRP80B for its quiet operation (39.0 dB(A) on high speed, 29.5 dB(A) on low), Wi-Fi control from a phone or voice assistant, and a straightforward indoor-unit-to-outdoor-unit piping run (up to 50m) that reduces installation complexity. The 7-year warranty and R32 refrigerant with lower global-warming potential (GWP) appeal to environmentally conscious buyers and those planning long-term comfort. An integrated dehumidifying function (3.0 L/h) helps manage tropical moisture without running cooling mode constantly.
Features
- 8.0kW dual-mode capacity — rated 8.0 kW cooling and 8.5 kW heating, covering medium to large lounge rooms and open-plan layouts up to 53m² (2.6m ceiling).
- Inverter technology — modulates compressor speed to maintain a set temperature without on-off cycling, reducing energy consumption by 30–40% vs fixed-speed systems.
- Wi-Fi app control — operates via iOS or Android app from anywhere with internet; no special wiring needed, connects through home router.
- Voice control enabled — works with Amazon Alexa and Google Home voice assistants for hands-free temperature and fan-speed adjustment.
- GoldGuard nano-coated condenser — outdoor coil treated with nano-technology to prevent bacteria growth, oxidation, and corrosion; outperforms standard coils in coastal and tropical salt-air exposure.
- Ultra-quiet operation — 39.0 dB(A) on high speed (conversational voice level) and 29.5 dB(A) on low (library quiet); suitable for bedrooms and living rooms.
- 3D airflow with swing control — horizontal and vertical blade movement distributes cool or warm air evenly across the room without dead zones.
- Demand Response Enabling Device (DRED) — responds to critical-peak pricing signals from energy providers, allowing automatic load reduction during peak-demand hours.
- Dehumidifying function — removes up to 3.0 litres of moisture per hour during humid summer without forcing cooling mode, maintaining comfort in tropical climates.
- Sleep mode — two-way temperature control that mimics outdoor air temperature to support natural sleep cycles without sudden temperature swings.
- R32 low-GWP refrigerant — next-generation refrigerant with 68% lower global-warming potential than older R410A, plus improved energy efficiency at lower charge volumes.
- Turbo heating and cooling — rapid ramp-up mode to reach set temperature 20–30% faster on first start-up during extreme seasonal transitions.
- 7-year warranty — full parts and labour coverage (for systems installed after 1 April 2025), reflecting manufacturer confidence in component longevity.
- Timer control — delay on/off function (30 minutes to 24 hours) allows pre-cooling before arrival home or automatic shut-down overnight.
- Wall-mounted indoor unit only — does not include outdoor condenser; outdoor unit (HONRP80) must be site-sourced and installed by a licensed air-conditioning technician.
Where to use
- Open-plan lounges and kitchens — the HSNRP80B's 8.0 kW capacity suits 40–53m² open rooms where a single wall-mounted head delivers even temperature across the space without interior partition walls.
- Renovation and new-build homes — compact indoor unit (1082 × 337 × 234 mm) fits on lounge or bedroom walls; outdoor unit (890 × 673 × 342 mm) sits on a standard roof or concrete ground pad.
- Master bedroom or media room — quiet operation at 29.5 dB(A) on low speed makes the HSNRP80B suitable for sleep zones; sleep mode automatically adjusts temperature to support rest.
- Coastal properties and tropical homes — GoldGuard nano-coating protects the outdoor condenser from salt spray, humidity, and bacterial growth in harsh salty or humid air environments.
- Homes with smart home integration — Wi-Fi and voice-control compatibility with Alexa and Google Home appeals to tech-forward owners who want appliance automation.
- Energy-conscious households — inverter technology and R32 refrigerant lower operating costs and environmental impact; demand response (DRED) enables off-peak rate optimization.
- Rental properties and holiday homes — 7-year warranty, low maintenance (self-cleaning filters), and remote app control allow property managers to troubleshoot temperature issues remotely.
The Rinnai HSNRP80B is not designed for outdoor installation, ceiling cavity mounting, or window-mounted applications. The wall-mounted indoor unit requires interior wall space at least 1.5 metres above floor level and free of obstructions; placement in tight cupboards or enclosed spaces reduces airflow efficiency. Do not install in bathrooms or areas with persistent water splash or high humidity without dedicated drainage (condensate outlet). The outdoor condenser must be exposed to ambient air and free of large vegetation overhang; placement directly beneath eaves or in confined backyards reduces cooling efficiency and may violate local noise regulations.
