Rinnai Hot Water System FAQs

Common questions about choosing, ordering and installing Rinnai heat pump, electric, natural gas and LPG hot water systems.

What are Rinnai hot water systems best suited for?

Rinnai hot water systems are best suited to homes wanting a trusted brand with options across heat pump, electric storage and instant gas hot water. The right Rinnai system depends on your household size, energy source, hot water demand, installation location and existing setup.

Which Rinnai hot water system should I choose?

Choose a Rinnai heat pump if you want improved energy efficiency, a Rinnai electric storage system if you want a straightforward electric replacement, or a Rinnai Infinity continuous flow gas system if you want instant gas hot water in either natural gas or LPG.

What is the Rinnai Enviroflo GR 300L heat pump best suited for?

The Rinnai Enviroflo GR 300L heat pump is best suited to family homes wanting an energy-efficient stored hot water system with strong everyday capacity. It can be a good option for households replacing an older electric storage system and wanting lower energy use.

What is the Rinnai 250L electric hot water system best suited for?

The Rinnai 250L electric hot water system is best suited to family homes wanting simple, reliable electric storage hot water. It can suit households needing stored hot water for showers, kitchens and laundries where an electric replacement is preferred.

What is the Rinnai Infinity B26 natural gas system best suited for?

The Rinnai Infinity B26 natural gas system is best suited to homes connected to mains gas that need strong continuous flow hot water. It can suit family homes and higher-demand households, depending on shower flow rate, water pressure, climate, gas supply and usage habits.

What is the difference between Rinnai natural gas and LPG models?

Rinnai natural gas models are for homes connected to mains gas, while Rinnai LPG models are for homes using bottled gas. The correct gas type must be selected before ordering because natural gas and LPG units are not interchangeable without the correct manufacturer-approved setup.

Can I replace my old hot water system with a Rinnai?

In many cases, a Rinnai hot water system can replace an older electric, heat pump or gas hot water system. The new unit still needs to suit the existing location, plumbing connections, energy source, electrical or gas requirements, drainage, clearances and current compliance requirements.

Can I buy a Rinnai hot water system supply only?

Yes. Choose supply only if you already have a licensed plumber, gas fitter, electrician or suitable installer arranged. Supply-only pricing is for the Rinnai hot water system only and does not include installation, valves, old unit removal, disposal, electrical work, gas work, pipework changes or compliance upgrades unless selected separately.

Can I order a Rinnai hot water system supplied and installed?

Yes. Supplied and installed options are available for selected Rinnai hot water systems in eligible Brisbane and Gold Coast service areas. Availability depends on your location, access, product type, existing setup, electrical or gas requirements and site conditions.

Are Rinnai gas hot water systems installed indoors?

Standard external Rinnai gas hot water systems are designed for outdoor installation. Do not assume a gas unit can be installed internally unless it is a manufacturer-approved internal or flued model and the installation meets all required ventilation, flueing and compliance requirements.

Do Rinnai heat pumps need clearance or ventilation?

Yes. Rinnai heat pump systems use surrounding air to help heat the water, so clearance and ventilation are important. The unit must be installed in a suitable position that meets the manufacturer’s airflow, drainage and service access requirements.

Is a Rinnai Infinity system the same as gas storage?

No. A Rinnai Infinity system is an instant gas continuous flow unit that heats water as it passes through the system. Gas storage hot water systems heat and store water inside a tank. The right option depends on household demand, gas supply, space and installation setup.

Does installation include electrical work?

Electrical work is not automatically included unless shown in the selected installation option or chosen as an add-on. Some Rinnai electric, heat pump or continuous flow replacements may require electrical checks, circuit changes, isolators, timers, power points or other upgrades by a licensed electrician.

Does installation include gas work?

Gas work is not automatically included unless shown in the selected installation option or chosen as an add-on. Some Rinnai gas replacements may require gas compliance checks, regulator work, pipework changes, isolation valves, gas sizing upgrades or other work by a licensed gas fitter.

Does installation include old system removal and disposal?

Old system removal and disposal are not automatically included unless shown in the selected installation option or chosen as an add-on. Access, location, tank size, stairs, mounting, pipework and site conditions can affect what is required.

Do you install Rinnai hot water systems in Brisbane and the Gold Coast?

Supplied and installed options are available for selected Rinnai hot water systems in eligible Brisbane and Gold Coast service areas. Availability depends on the selected Rinnai product, your address, access, existing system and installation requirements.
