Rinnai ducted is a smart, well-priced way to heat and cool a whole home from a single reverse cycle system. A slimline fan coil sits hidden in your roof space and pushes conditioned air through ducts to discreet ceiling diffusers in every room, running on a Twin Rotary inverter compressor and R32 refrigerant. The whole 7 to 18 kW range works on standard single-phase power and gives you up to 8 zones with Wi-Fi control from the Rinnai Home App. At BM Heating & Cooling, we install Rinnai ducted systems right across Melbourne, sizing, zoning and commissioning each one properly so you get quiet, even comfort and low running costs, with any VEU rebate applied straight to your invoice.

Why Choose Rinnai Ducted for Your Home


Rinnai is one of Australia's most trusted home comfort brands, and its ducted reverse cycle range is built for exactly what Melbourne homes need: reliable heating and cooling from one quiet, efficient system that does not break the budget.

The current 7 to 18 kW range runs on a Twin Rotary inverter compressor and R32 refrigerant, so the system holds a steady temperature while drawing less power, and the noisy components stay outside and in the roof so your living areas stay peaceful.

  • Whole-home comfort: heat and cool every room from a single ducted system.
  • Up to 8 zones: condition only the rooms you are using to cut running costs.
  • Wi-Fi and app control: run it from the Rinnai Home App, Google Home, Alexa or Apple.
  • Single-phase and slimline: the whole range fits standard power and tight ceiling cavities.

How a Rinnai Ducted System Works


A ducted reverse cycle system moves heat rather than burning fuel to make it. In winter it draws warmth from the outside air and releases it inside; in summer it reverses the cycle and pulls heat out of your home. That is why it delivers far more comfort per unit of electricity than an old gas or electric heater.

A Rinnai ducted system has four main parts:

  • Concealed fan coil: a slimline indoor unit hidden in the roof space, sized to your home.
  • Outdoor condenser: a Twin Rotary inverter unit installed neatly beside the home.
  • Ducts and diffusers: carry conditioned air to each room through discreet ceiling outlets.
  • Controller: a wired touchscreen controller with Wi-Fi, plus the Rinnai Home App for your phone.

Zoning & Smart Control


Zoning is where a Rinnai ducted system saves you money. You can split the system into up to 8 individual zones and only condition the rooms you are actually using.

Room-by-room control: run the living areas by day and the bedrooms at night, or shut unused rooms off entirely.

Wi-Fi and the Rinnai Home App: manage it from the wired touchscreen controller or the app, so you can adjust comfort or switch zones from your phone before you get home. It works with Google Home, Amazon Alexa and Apple.

Inverter efficiency: the DC Twin Rotary compressor ramps up and down smoothly instead of switching hard on and off, holding a steady temperature while drawing less power.

Set and forget: schedules, favourites, a sleep timer and filter-clean reminders are all built in, so the system runs the way your household actually lives.

Zoning plus inverter efficiency is what keeps running costs down while every room stays comfortable.

VEU Rebate

VEU Rebate Eligible

A high-efficiency ducted reverse cycle system, especially replacing an old ducted gas heater, is the kind of upgrade that can qualify for the Victorian VEU rebate. We confirm current eligibility with your quote.

Energy Efficiency & the VEU Rebate


The Rinnai R32 ducted range pairs a DC Twin Rotary inverter compressor with R32 refrigerant, which improves efficiency and uses a refrigerant with a lower global warming potential than the older R410A. That efficiency, with up to 3.4-star cooling, is also what can make a ducted reverse cycle system eligible under the Victorian Government's Victorian Energy Upgrades (VEU) program, especially when replacing an old ducted gas heater.

How the VEU Discount Works

An approved high-efficiency ducted system generates energy-saving certificates based on the emissions it avoids over its lifetime. As an accredited installer, BM Heating & Cooling converts those certificates into a discount that comes straight off your install price on the day, with no claim forms and no income test.

A minimum customer contribution applies, and both the discount and the co-payment are set by the scheme and are changing through 2026. Rather than quote a number blind, we confirm your current eligibility and figure as part of your free quote.

Warranty & Professional Installation


Rinnai backs its ducted air conditioning range with a 7-year limited warranty. That warranty relies on correct sizing, installation and commissioning, which is exactly what you get with a licensed installer. We match the capacity to your home, set the airflow for your duct runs, balance it across every zone and commission the system properly before handover.

Getting the sizing right matters: an undersized system struggles on the coldest and hottest days, while an oversized one short-cycles and wastes energy. We assess your floor area, ceiling space, insulation and layout so the system we recommend, whether a 7 kW R32 unit or a 24 kW system for a large home, is the right fit.

The Rinnai Outdoor Unit


Every Rinnai ducted system pairs the concealed fan coil with a matched outdoor condenser. These DC Twin Rotary inverter units are built for Australian conditions, running efficiently and quietly through both winter heating and summer cooling.

The right outdoor unit depends on your system: the 7 to 18 kW R32 range runs on standard single-phase power, so most homes avoid a costly three-phase upgrade, while the 20 to 24 kW range steps up the capacity for larger homes.

Every install is carried out by licensed, ARCtick-certified technicians, backed by Rinnai's 7-year limited warranty and our own workmanship guarantee.

Rinnai Ducted FAQs


Most Melbourne homes use the Rinnai R32 ducted range, which comes in 7, 9, 11, 13, 15 and 18 kW sizes and runs on single-phase power. Larger homes that need more grunt step up to the 20 to 24 kW R410A range. We size the system to your floor area, ceiling space, insulation and zoning needs so it is neither undersized nor oversized.

The Rinnai ducted range supports up to 8 individual zones, each with independent temperature control. That lets you run the living areas by day and the bedrooms at night, or shut unused rooms off entirely, which cuts running costs.

Yes. Rinnai ducted systems use a wired programmable touchscreen controller with Wi-Fi, plus the optional Rinnai Home App for remote control from your phone. The app works with Google Home, Amazon Alexa and Apple, and includes schedules, favourites, a sleep timer and filter-clean reminders.

No. The whole Rinnai R32 ducted range, from 7 kW up to 18 kW, runs on standard single-phase 230 volt power, so most homes avoid a costly three-phase electrical upgrade. The larger 20 to 24 kW R410A systems are used for big homes where more capacity is needed.

A high-efficiency ducted reverse cycle system, especially when it replaces an old ducted gas heater, is the kind of upgrade that can qualify under Victorian Energy Upgrades. The discount is applied upfront to your invoice with no income test. Rebate and co-payment amounts are set by the scheme and are changing through 2026, so we confirm current eligibility and pricing when you get a quote.

The current 7 to 18 kW Rinnai ducted range uses R32 refrigerant, which has a lower global warming potential than the older R410A and improves energy efficiency when paired with the Twin Rotary inverter compressor. The larger 20 to 24 kW systems use R410A.

The compressor sits outside and the fan coil is hidden in the roof, so your living areas stay quiet. The DC inverter compressor ramps smoothly instead of switching hard on and off, and correct sizing and airflow setup by an accredited installer keeps duct noise low.

Rinnai backs its ducted air conditioning range with a 7-year limited warranty. Correct sizing, installation and commissioning by a licensed installer protects that warranty, which is exactly how BM Heating & Cooling installs every system.
