Rinnai Infinity 20 Gas Hot Water System Sydney

Enjoy dependable continuous hot water with professional advice from Abundant Hot Water Sydney.

The Rinnai Infinity 20 is a compact gas continuous-flow hot water system developed for households that want reliable hot water without installing a large storage cylinder. Rather than storing and repeatedly reheating water, the system activates when a hot tap is opened and heats the water as it passes through the unit.

Rinnai designed the Infinity 20 primarily for one-bathroom homes, with potential suitability for up to two bathrooms in warmer climates, depending on the property’s outlets, water temperature, flow requirements and usage patterns. The system has a maximum rated flow of 20 litres per minute at a 25°C temperature rise.

A Continuous Supply of Hot Water

One of the principal advantages of the Rinnai Infinity 20 is its continuous-flow operation. There is no storage tank to empty during normal use. Provided the unit has the correct gas, water and electrical supplies, it heats water when a hot-water outlet is opened.

This makes continuous-flow technology attractive to households that want to reduce the risk of running out of stored hot water after consecutive showers.

The system must still be correctly sized for the number of outlets that may operate simultaneously. A 20-litre unit may not be appropriate for a large home with several bathrooms or high concurrent demand.

Designed for Smaller Sydney Homes

The Infinity 20 is most suited to properties with modest hot-water requirements, including:

• One-bathroom homes
• Townhouses and villas
• Granny flats
• Smaller family homes
• Selected apartments where installation conditions permit
• Properties replacing a similar 20-litre continuous-flow system

Rinnai’s sizing information identifies the Infinity 20 as suitable for one shower outlet in cooler climates and one to two outlets in warmer climates. Actual performance can be affected by inlet water temperature, outlet flow rates and simultaneous usage.

A proper site assessment is therefore important before selecting or replacing any hot water system.

Frequently Asked Questions

Is the Rinnai Infinity 20 discontinued?

Yes. Rinnai’s official Australian product page currently identifies the original Infinity 20 as discontinued and points customers towards the current replacement model.

What replaced the Rinnai Infinity 20?

The Rinnai Infinity B20 is the current 20-litre model linked by Rinnai as the replacement. A site inspection is still recommended because connections and installation requirements may differ.

Is the Rinnai Infinity 20 suitable for a one-bathroom home?

Yes. Rinnai designed the system primarily for one-bathroom homes. It may accommodate up to two shower outlets in warmer climates, but suitability depends on water temperature, outlet flow and simultaneous usage.

Does the Rinnai Infinity 20 run out of hot water?

The unit heats water continuously while a suitable supply of gas, water and electricity is available. Unlike a storage tank, it does not have a fixed quantity of stored hot water to exhaust.

Is it available for Natural Gas and LPG?

The Infinity 20 was offered in separate Natural Gas and LPG models. The correct gas model must be selected for the property.

Can my existing Rinnai Infinity 20 be repaired?

Possibly. Repair suitability depends on the fault, condition of the appliance, availability of parts, installation condition and repair cost. An inspection is required before a reliable recommendation can be made.

What is the flow rate of the Infinity 20?

The original model has a maximum rated flow of 20 litres per minute at a 25°C temperature rise. Actual outlet flow may vary according to incoming water temperature and system conditions.

Can I replace it with a larger Rinnai model?

A larger model may be appropriate for a home with greater hot-water demand, but the existing gas pipe, water supply and installation position must be assessed first.

Can I install the unit myself?

No. Rinnai states that its gas continuous-flow appliances must be installed, maintained and removed by an authorised person.
