Rinnai HONRTX70 / HINRTX70 Review: 7kW Split System

The Rinnai HONRTX70 / HINRTX70 is the outdoor and indoor unit pair behind the Rinnai TX Series 7.0kW single-split system, sold as the HSNRTX70. It heats and cools one large room, not a whole home.

This review covers what it offers, who it suits and whether it can qualify for the Victorian government split system rebate. The discount sits under the Victorian Energy Upgrades program, which most people search for as the Victorian energy rebate.

Figures come from Rinnai's TX Series brochure and product page. One outdoor unit serves one indoor unit.

1. 3D Airflow: Louvres swing horizontally and vertically to spread air across a large room.
2. Follow Me: Reads the temperature at the remote, which helps in open-plan rooms where you sit far from the unit.
3. Turbo+: Rinnai's "6 degrees in 10 minutes" claim comes from testing a 3.5kW unit, so it does not describe this model.
4. HEPA and Cold Catalyst filtration: Rinnai cites Intertek testing for up to 99 per cent reduction in bacteria and dust. It does not publish filter replacement intervals, so ask your installer.
5. Wi-Fi and voice control: The NetHome Plus app (a third-party app with its own privacy terms) works with Google Assistant and Alexa.
6. DRED and GoldGuard: DRED allows demand response, subject to your energy provider. GoldGuard coats the coil against corrosion, though the warranty excludes salt and corrosive environments, so coastal owners should ask how that applies.

1. Large open-plan spaces: Rinnai's selection guide adjusts for sun, insulation and windows. The Victorian Government's buyer's guide suggests 5 to 8kW for 41 to 60 square metres. The two overlap but differ, so get an on-site load assessment.
2. Small rooms: The same guide lists 2.5 to 3kW for rooms up to 20 square metres and warns that oversized systems cost more and cause temperature swings.
3. Several rooms: A single split serves one zone. For more, consider a different product type such as the one in our Rinnai 13kW ducted review.

1. Heating ratings (3.0, 2.5 and 2.0 stars) sit below cooling ratings. Victorians typically use more energy for heating, so check the label for your zone on the Energy Rating website.
2. The system draws about 1.9kW at rated heating output.
3. Your bill depends on your tariff, run time, set temperature, insulation, outdoor temperature, sizing, installation quality and filter care. Any dollar figure without your tariff is a guess, so this review gives none.

1. Cold weather: Rinnai says heating capacity falls as outdoor temperatures drop. Ask how the unit performs at your local winter temperatures.
2. Noise: Indoor sound ranges from 21.0 to 52.0dB(A) and the outdoor unit rates 61dB(A) at 1m. No independent comparison exists in the documents reviewed, so check where the outdoor unit sits relative to bedrooms and neighbours.
3. Electrical and pipework: Rinnai recommends a 25A breaker. It lists 15m of pipe without extra charge and 50m as the maximum.
4. Wi-Fi warranty: Rinnai's booklet lists Wi-Fi devices at one year, so ask whether that covers the TX Series module.
5. Maintenance: The warranty depends on following the manual, including filter cleaning. See our guide to getting your split system ready for summer.

Yes, it is listed as eligible in Rinnai's VEU guide, but that is a manufacturer statement, not the official register. A product can be installed under the program only when approved on the ESC's Register of Products, so have your provider check both model codes (HONRTX70 / HINRTX70).

The amount. Indicative discounts for a 3 to 9kW non-ducted system run from $630 to $1,610 replacing a non-ducted gas heater, up to $840 replacing a hard-wired electric heater and $210 replacing a non-ducted reverse cycle unit. Your quote is the real figure. Non-ducted systems under 10kW carry a $200 minimum customer contribution. The 30 September 2026 increases target ducted and larger multi-split systems.

1. An on-site load assessment confirms 7kW suits your room.
2. The quote lists HSNRTX70, HINRTX70 and HONRTX70, and the provider confirms them on the register.
3. Installation scope covers unit positions, pipe length, electrical work and drainage.
4. You have Rinnai's warranty booklet and know who services the system.
5. The quote shows product, installation, discount and your contribution as separate lines.

It is a well-featured 7kW single split for large living spaces, with inverter technology, Wi-Fi, filtration and a 7-year warranty. The sources reviewed contain no independent comparison, so it is not shown to be the best, quietest or cheapest. Consider it for a large, insulated open-plan room. Smaller rooms or several rooms may suit another system.

Before you buy independently, our team at EcoOrigin, a listed accredited provider, can check your model and upgrade against current requirements, explain the discount and give you a written quote. Send us your room details and the model you are considering.

1. Is the Rinnai HONRTX70 / HINRTX70 eligible for the Victorian government split system rebate?

Rinnai lists it as eligible. The official test is approved status on the ESC register when your provider creates the certificates. Your household and existing system also matter.

2. How do I check this model for a Victorian energy rebate?

Ask your accredited provider to confirm HINRTX70 and HONRTX70 on the Register of Products, and get the codes on your quote.

3. How much could I save on an eligible installation?

It depends on what the system replaces. Government indicative figures for 3 to 9kW non-ducted systems range from $70 to $1,610. Only your quote confirms the amount.

4. Can EcoOrigin arrange both the rebate and installation?

Yes. EcoOrigin is a VEU accredited provider. The program is market-based, so confirm it is offering this upgrade in your area.

5. What affects running cost?

Tariff, run time, set temperature, insulation, outdoor temperature, sizing and filter care. Rinnai's AEER and ACOP are test results, not bill estimates.

6. What warranty applies in Australia?

Rinnai lists 7 years residential. The booklet requires a qualified installer, regular maintenance and a claim within 30 days, and excludes corrosive environments.
