Jayco installed our Rinnai Infinity and the temperature control is excellent. Couldn't be happier. Whole job done in a couple of hours.

Our Rinnai was showing an error code and we had no hot water. Jayco came out quickly, diagnosed a flow sensor fault and fixed it on the spot.

We switched from a storage tank to a Rinnai continuous flow system. The upgrade is well worth it. Jayco made the whole process easy.

How much does a Rinnai hot water system cost to install in Sydney? expand_more

Rinnai installation costs depend on the model and any gas line modifications required. Rinnai continuous flow systems typically start from around $1,500 to $2,800 fully installed. Jayco Plumbing provides a free fixed quote. Call 0485 900 361.

What does a Rinnai error code mean? expand_more

Rinnai continuous flow systems display error codes when a fault is detected. Common codes include: Code 11 (no ignition), Code 12 (flame failure), Code 14 (thermal fuse), Code 16 (overheating), Code 51 (gas pressure fault), Code 61 (fan motor fault), Code 65 (water flow fault), Code 79 (inlet thermistor fault). Most faults require a licensed plumber to diagnose and repair safely. Call Jayco Plumbing on 0485 900 361.

Is Rinnai better than Rheem for hot water? expand_more

Both Rinnai and Rheem are excellent brands. Rinnai is widely regarded as the leading brand for continuous flow (instant) hot water, with superior temperature precision and a strong track record for reliability. Rheem has a broader range covering all system types and is a strong choice for electric storage. Jayco Plumbing can advise on the best brand and model for your specific situation. Call 0485 900 361.

Do you carry Rinnai units for same-day installation? expand_more

Yes. Jayco Plumbing carries popular Rinnai continuous flow models on our vehicles for same-day supply and installation across Greater Sydney. Call 0485 900 361 early in the day to secure a same-day booking.

How often should a Rinnai hot water system be serviced? expand_more

Rinnai recommends annual servicing for continuous flow systems, particularly in areas with harder water where scale build-up in the heat exchanger can reduce performance and efficiency over time. Jayco Plumbing offers annual Rinnai servicing across Sydney including descaling, inlet filter cleaning, and safety checks.
