How Much Does a Rinnai Heating System Installation Cost?
So, how much does a heating system installation cost in Sydney? Well, this all depends on the type of system and brand you choose, as well as the size of your residence. Rinnai offers some of the most reliable and energy-efficient heating system options on the market. If you are looking at individual rooms or an open-plan living area, a Rinnai Gas Heater could be your perfect choice. The total cost of supply and installation of this system can range from $1,500 to $3,000, depending on the level of coverage you are looking for. Another strong option is the Rinnai Ducted Gas Heating. This system provides a quiet but powerful heating coverage and costs between $3,000 to over $7,000 to be fully installed.

Great service and work by Zac and his crew! Zac came and did the quote and provided his recommendations to help with deciding which option I wanted. Then the team came and performed the job (deep clean + replacing old ducts + add zoning) in a timely and efficient manner. They did their best in keeping the place neat and tidy which is highly appreciated. The air con performance after the job is significantly better! Cooling the room in no time and much stronger! Very happy with the result Highly recommend overall!Posted on Google![]()

Outstanding service when we needed it most. After 20 years our airconditioning packed it in a week before Christmas. Proven replaced the system two days before Christmas. Their team arrived at 7.30am and finished the job at 7pm. I cannot recommend them highly enough.Posted on Google![]()

To clean your Rinnai Gas Heater, make sure to first switch off the unit and disconnect it from the power and gas supply. Use a brush to gently remove dust and built-up debris within the vents, outer casing, and air filters. It is important to avoid using water or harsh chemicals. Models that have removable filters that can be taken out and cleaned using a vacuum or water, just ensure that the filter is completely dry before your reinstall it.
Always refer to your Rinnai user manual for specific instructions, and if you suspect that your unit requires a deeper clean or has serious carbon or dust build-up, it’s best to book a professional service such as the expert team at Proven Air Sydney to ensure your heater is safe, clean, and ready to perform to its full capacity.
Rinnai has established a strong reputation in Australia for a reason, and a large contributing factor is their top-priority focus on safety. These heaters come packed with an array of technologically advanced features, such as flame failure detection, tilt-switch cut-off, and oxygen depletion sensors. These functions ensure that your unit shuts off in unsafe conditions, such as low oxygen levels. Rinnai’s heaters undergo extensive testing before delivery to ensure reliable and safe performance. To ensure peace of mind, consider getting in touch with a Proven Air technician to undergo regular servicing so that optimal safety and efficiency are always met.
Yes, it is recommended that you call in a professional to have your Rinnai Gas Heater serviced semi-regularly to ensure it continues to operate safely and efficiently. Rinnai recommends that your heater be serviced by a licensed technician at least once every two years. However, if you do use it regularly, then an annual servicing is recommended. Not only does this ensure your unit’s safety, but it also extends the lifespan of your heater. Call in an expert from Proven Air Sydney today to service your Rinnai unit.
Rinnai Gas Heaters are some of the most energy-efficient systems on the market. They use only a small amount of electricity to power specific components of the system, such as the ignition system, fan, and electronic controls. The primary heat source in the systems is natural gas. Some other basic Rinnai models don’t require electricity to operate. It’s important to talk with an experienced technician about all available models.
A Rinnai gas heater works by burning natural gas or LPG to produce heat, which is then circulated throughout your room. When you turn the heater on, gas flows to the burner and is ignited either by a pilot light or electronic ignition, depending on the model. The heat produced warms a heat exchanger, and a fan helps distribute the warm air evenly. Rinnai heaters often come with built-in thermostats, timers, and safety features like flame failure devices and oxygen depletion sensors, which are important for meeting Australian safety standards. The result is efficient, controlled heating that’s ideal for Australian homes in cooler months.
Rinnai has established a strong reputation thanks to their long-term durability. On average, Rinnai Water Heaters last between 15 to 20 years when properly maintained and serviced. Hiring a professional to clean your filters, check for scale build-up and other such maintenance issues can help to extend the lifespan of your Rinnai system. Each Rinnai system also comes backed with a generous warranty to ensure an extra level of peace of mind. With proper care, a Rinnai Water Heater can deliver reliable hot water for many years.
The cost of a Rinnai water heater in Australia can vary widely depending on the type and capacity of the unit. For continuous flow gas models, prices generally range from around $895 for a basic 16L model to over $2,200 for high-capacity 32L units. Electric storage systems typically cost between $1,200 and $1,500, while energy-efficient heat pump models start from approximately $1,100 and can exceed $2,800 when installation is included. Solar hot water systems are the most expensive upfront, with prices starting from around $5,000. It’s also important to factor in installation costs and potential government rebates, which can influence the final price. Always consult a licensed professional, such as the team at Proven Air Sydney, to ensure the unit is suitable for your household’s needs.
