Rinnai 23.5kW Mini VRF (MVRFON6H20): A Full Guide for Victorian Homes
Rinnai 23.5kW Mini VRF (MVRFON6H20): A Full Guide for Victorian Homes
Everything you need to know about Rinnai’s 23.5kW Mini VRF outdoor unit — zoning, wifi control, running costs and VEU rebate eligibility.
If you’re heating and cooling four to six rooms from a single outdoor unit, the Rinnai MVRFON6H20 is one of the most requested options for Victorian homes right now. It’s the outdoor unit for Rinnai’s Mini VRF (Variable Refrigerant Flow) range — a 23.5kW-class system built for renovations, multi-storey homes, and properties where outdoor space or piping runs are tight.
From 30 September 2026, the mandatory VEU co-payment for multi-head systems of 10kW or more rises from $1,000 to $3,000 (inc. GST), with an incentive cap on large multi-splits. At 23.5kW, the MVRFON6H20 sits well above this threshold — booking installation before this date locks in the current, lower co-payment.
What is the Rinnai MVRFON6H20?
The MVRFON6H20 is the outdoor unit at the core of Rinnai’s Mini VRF system. Unlike a standard multi-split, VRF technology continuously fine-tunes how much refrigerant reaches each connected indoor unit based on real-time demand, rather than simply cycling zones on or off. That means tighter, room-by-room temperature control and typically better efficiency when different rooms are used very differently throughout the day.

Why homes are choosing Mini VRF
- Individual room control — each of the up to six indoor units can run its own temperature and schedule independently.
- Slimline piping — designed to suit renovations and multi-storey homes where running large ductwork isn’t practical.
- Quiet operation — lower outdoor noise than older-generation multi-splits, with a neater external footprint.
- Wifi as standard — full app control of every zone via App+, no separate smart controller purchase required.
VEU rebate eligibility
As a reverse cycle system capable of both heating and cooling, the Rinnai MVRFON6H20 meets the core VEU eligibility requirement, provided it’s installed as part of an approved product listing. Final discount amounts depend on your property and what’s being replaced — the largest incentives typically apply when an existing ducted gas heater is decommissioned.
- Must be an approved reverse cycle system on the ESC’s VEU Register of Approved Products
- Must carry a minimum 5-year warranty to qualify — confirm current warranty terms with your installer
- Co-payment currently $1,000 for systems this size, rising to $3,000 from 30 September 2026
- Larger discounts typically apply when replacing ducted gas heating rather than an existing electric system
Frequently Asked Questions
How many rooms can the Rinnai MVRFON6H20 heat and cool?
Up to six rooms, each on its own indoor unit and independent temperature setting, from the one 23.5kW outdoor unit.
Is the Rinnai MVRFON6H20 eligible for the VEU rebate?
Reverse cycle systems on the ESC’s Register of Approved Products — including Rinnai’s Mini VRF range — are generally VEU-eligible, subject to installer assessment and the minimum warranty requirement.
What makes VRF different from a standard multi-split?
VRF continuously varies refrigerant flow to each indoor unit based on real-time demand, giving more precise zone-by-zone control and typically better efficiency than a standard multi-split sharing one compressor output.
