Rinnai's VRF offering is the Mini VRF, a compact Variable Refrigerant Flow system that sits between a home multi split and a full commercial VRF. One small outdoor unit runs several indoor units through a single refrigerant network, varying refrigerant flow to each zone so every room gets exactly the heating or cooling it needs, with built-in Wi-Fi control. It is ideal for larger homes, renovations, townhouses and light commercial spaces. At BM Heating & Cooling, we design and install Rinnai Mini VRF systems right across Melbourne. As an ARCtick-certified, VEU-accredited installer, we size the outdoor unit to the rooms, design the pipework and zoning, install it neatly and confirm any rebate you qualify for.

Why Melbourne Chooses Rinnai Mini VRF


Rinnai is a name Australian homes have trusted for decades, and its Mini VRF brings VRF-style zoning to homes and small buildings without the bulk of full commercial plant. One compact outdoor unit runs several rooms, each on its own temperature.

The small outdoor footprint and slimline pipework make Mini VRF easier to fit into an existing home or renovation, and built-in Wi-Fi means every zone is controlled from your phone. It is the natural step up when a multi split runs out of flexibility.

  • Compact outdoor unit: runs several indoor units from one small, easy-to-place condenser.
  • Mix indoor styles: combine hi-wall, ducted and cassette units on the one system.
  • Built-in Wi-Fi: control the system and each zone from your phone.

How Rinnai VRF Works


The heart of the system is the compact Rinnai outdoor unit. A single condenser connects to several indoor units through one refrigerant network, and each indoor unit runs on its own controller and temperature. Its small size and slimline pipework suit multi-storey homes, renovations and townhouses where a full commercial VRF would be overkill.

  • Compact outdoor plant: a small footprint that fits tight side setbacks and courtyards.
  • Independent zones: every indoor unit runs on its own controller and temperature.
  • Mix and match: hi-wall, ducted and cassette indoor units on the one outdoor unit.
  • Wi-Fi control: run the whole system and each room from the app.

Rinnai VRF Outdoor & Indoor Units

Mini VRF Outdoor Unit

A compact outdoor unit that runs several indoor units from one refrigerant network. Its small footprint and slimline pipework make it ideal for renovations, townhouses and multi-storey homes where space is tight, with built-in Wi-Fi control.

Wall-Mounted

A quiet hi-wall head that mounts high on the wall in bedrooms, living areas, offices or apartments. Several wall heads run from the one compact outdoor unit, each with its own set temperature and its own room, with built-in Wi-Fi control.

Zone Control, BMS Integration & Quiet Running


Rinnai Mini VRF is built around simple, room-by-room control.

Zone-by-zone control: every indoor unit runs on its own controller and temperature, so bedrooms and living areas can differ.

Wi-Fi and app control: built-in Wi-Fi lets you switch on, schedule and adjust each zone from your phone.

Quiet and compact: the small outdoor unit is easy to site away from living spaces and neighbours, and the indoor units run quietly in the background.

Inverter Efficiency & Running Costs


Rinnai Mini VRF is a full inverter system. The compressor ramps its output up and down to match how many indoor units are running and how hard they are working, instead of switching hard on and off, which holds a steadier temperature, runs more quietly and cuts running costs compared with older fixed-speed units.

Running a single compact outdoor unit for several rooms is more space-efficient than a separate condenser for every room, and running fully electric lets you pair the system with rooftop solar to lower running costs further.

Where Rinnai Mini VRF Makes Sense


Mini VRF suits larger homes, renovations, townhouses and multi-storey homes where outdoor space is tight, plus small offices and suites. It gives more zoning flexibility than a multi split while staying compact and residential-friendly.

For a couple of rooms a reverse cycle multi split system may be all you need, and for a large commercial building a full VRF is the better fit. We help you land on the right one at the quote.

Installation, Warranty & VEU Rebates in Victoria


A system only performs as well as its design and install. Our licensed, ARCtick-certified technicians size the outdoor unit to the load, select and place each indoor unit, run and insulate the pipework, set up the Wi-Fi control and test the system in both heating and cooling before we hand it over. Rinnai Mini VRF systems are backed by the manufacturer's warranty when installed correctly, and we stand behind every job with our own workmanship guarantee.

Eligible high-efficiency reverse cycle systems can also attract a discount under the Victorian Government's Victorian Energy Upgrades (VEU) program, particularly when replacing older heating. Eligibility is set per model on the VEU register and the work has to be done by an accredited provider, which we are.

How the VEU Discount Works

An approved high-efficiency system generates energy-saving certificates based on the emissions it avoids over its lifetime. As an accredited installer, we convert those certificates into a discount that comes straight off your install price on the day, rather than something you claim back later.

Eligibility and the certificate value shift with the program settings and the activity, and commercial projects are assessed differently to homes, so we confirm your current eligibility and figure as part of the quote rather than quoting a number blind.

Professional Rinnai VRF Design & Installation


A VRF system is only as good as the design and install behind it. Undersized plant, poor pipework or a weak control strategy can rob any system of efficiency and comfort, which is why it pays to use an experienced, licensed HVAC team.

BM Heating & Cooling has installed reverse cycle systems across Melbourne for years. We plan the zoning, size the outdoor plant, run the pipework neatly, set up the controls or BMS integration and commission every zone before we leave.

Every install is carried out by licensed, ARCtick-certified technicians and backed by the manufacturer's warranty and our own workmanship guarantee.
