Inverter Technology, Efficiency & Running Costs
The Rinnai inverter multi split range is a full inverter running on R32 refrigerant. The inverter compressor ramps its output up and down to match how many indoor heads 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. R32 is also a lower global warming potential refrigerant than the older R410A it replaces, and the hi-wall heads add ECO+ energy-savings technology to trim consumption further.
Running a single outdoor unit for several rooms is also more space-efficient than a separate condenser for every room, which is why multi split suits apartments, townhouses and homes with limited outdoor space. Running fully electric lets you pair the system with rooftop solar to lower running costs further.
Heating Performance for Melbourne Winters
Melbourne winters are where a good reverse cycle system earns its keep. A Rinnai multi split heats every connected room, so on a cold morning you can warm the bedrooms and living area from the one outdoor unit, each to its own comfortable temperature.
Because reverse cycle heating moves heat rather than burning fuel, it is one of the cheapest ways to warm a home, typically well below the running cost of gas or electric-element heaters. A correctly sized Rinnai multi split can be the main source of winter warmth across several rooms, then flip to efficient cooling through summer on the same system.
How Many Indoor Units Can One Outdoor Unit Run?
A Rinnai inverter multi split can connect up to six indoor units to a single outdoor unit, each fed through its own pipework and run on its own controller. That covers most homes, from a two-room upgrade to a whole-house fit-out across living areas and bedrooms.
The outdoor unit is sized to the rooms it will serve, so if you may add a room later it is worth planning that in upfront. We work out the right outdoor unit and the best mix of indoor units for your home at the free quote, so every room gets the style and capacity that suits it.
Installation, Warranty & VEU Rebates in Victoria
Getting the most out of a multi split comes down to correct sizing and a proper install. Our licensed, ARCtick-certified installers size the outdoor unit to the total load, match each indoor unit to its room, run and insulate the separate pipework to every head, make the electrical connection and test the system in both heating and cooling before we hand it over. Rinnai inverter multi split systems are backed by a 7-year limited warranty when installed correctly, and we stand behind every job with our own workmanship guarantee.
Eligible Rinnai reverse cycle systems can also attract a discount under the Victorian Government’s Victorian Energy Upgrades (VEU) program, particularly when replacing older, less efficient 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 generally applies to established Victorian homes, there is no income or means test, and a minimum customer contribution applies. The exact rebate value shifts with certificate pricing and program settings, so we confirm your current eligibility and figure as part of your free quote rather than quoting a number blind.
