Rinnai Builder Series B26 Continuous Flow Hot Water Sydney
Enjoy dependable hot water without the space requirements and standby heat loss associated with a traditional storage tank. The Rinnai Infinity B26, commonly searched for as the Rinnai Builder Series B26, is a compact continuous flow gas hot water system designed to heat water as it is required.
With a heating capacity of up to 26 litres per minute at a 25°C rise, the current Infinity B26 is designed for one to two-bathroom homes and may serve up to three shower outlets in warmer climates. Final suitability depends on the incoming water temperature, water pressure, outlet flow rates, gas supply and the number of taps or showers used simultaneously.
At Abundant Hot Water Sydney, we provide professional product advice, supply and installation for households throughout Sydney. Our experienced team can assess your property and determine whether the Rinnai B26 provides the right capacity for your family’s everyday hot water needs.
Rinnai B26 at a Glance
The Rinnai Infinity B26 is a gas-powered continuous flow unit that heats water when a hot tap is opened. Because it does not continually maintain a stored tank of heated water, energy is not being used to keep a large volume of water hot throughout the day.
The current model offers a six-star energy rating, Puretemp™ temperature-stability technology, precise temperature control and compatibility with both natural gas and LPG configurations. It can also support compatible Rinnai water controllers for greater convenience.
Key benefits include:
- Continuous hot water within the unit’s operating capacity
- 26-litre-per-minute heating capacity at a 25°C rise
- Six-star energy-efficiency rating
- Compact external design
- Natural gas and LPG models available
- Puretemp™ temperature-stability technology
- Minimum operating flow of 1.5 litres per minute
- Compatibility with low-flow shower fixtures
- Optional compatible hot water controllers
- Quality Japanese design and manufacturing
Continuous Hot Water When You Need It
A traditional storage system heats and stores a limited volume of water. Once that stored water has been used, the system needs time to heat another tank.
The Rinnai B26 operates differently. It begins heating water when a hot tap is opened and continues operating while the tap remains open, provided the household demand stays within the system’s capacity and the required gas, water and electrical services remain available.
This makes continuous flow technology particularly attractive for busy households where showers are often taken one after another.
Efficient Six-Star Gas Hot Water Performance
The current Rinnai Infinity B26 carries a six-star energy rating. Because continuous flow systems heat water on demand, they avoid the standby heat loss normally associated with keeping water hot inside a storage cylinder.
Actual household running costs will vary depending on:
- The number of people living in the property
- Daily hot water consumption
- Gas tariffs
- Shower duration
- Outlet flow rates
- Incoming water temperature
- Selected temperature settings
- The condition and design of the plumbing system
Abundant Hot Water Sydney can help you compare the B26 with other gas, electric, solar and heat pump options before you make a final decision.
Stable and Comfortable Water Temperatures
Temperature fluctuations can make showers uncomfortable, particularly when other taps are being turned on around the home. The Rinnai B26 incorporates Puretemp™ temperature-stability technology, which is designed to maintain a steadier outlet temperature during changes in water flow.
Compatible Rinnai water controllers may also be added, depending on the installation. These can provide household members with greater control over the selected water temperature.
Product Page FAQs
Is the Rinnai Builder Series B26 still available?
Rinnai’s older B26 page is currently marked as discontinued and directs customers to the Infinity B26 as the current model. Confirm the exact product code and availability before advertising or accepting an order.
Is the Rinnai B26 suitable for two bathrooms?
The Infinity B26 is generally designed for one or two-bathroom homes. Rinnai’s sizing guide indicates up to three shower outlets may be supported in warmer climates, but actual suitability depends on water pressure, incoming water temperature, fixture flow rates and simultaneous demand.
Does the Rinnai B26 provide continuous hot water?
Yes. The unit heats water as it flows through the system rather than drawing from a limited storage tank. Hot water can continue while the unit is operating within its rated capacity and the required services remain available.
What is the flow capacity of the Rinnai Infinity B26?
The current Infinity B26 has a rated heating capacity of 26 litres per minute at a 25°C water-temperature rise.
Is the Rinnai B26 available for natural gas and LPG?
Yes. Rinnai lists natural gas and LPG configurations for the current Infinity B26. The correct model must be selected for the property’s gas supply.
Can the Rinnai B26 replace a gas storage tank?
In many properties it can, but the changeover may require alterations to the gas line, water pipes, electrical supply or installation location. A site assessment is required before confirming the replacement.
Does the Infinity B26 require electricity?
Continuous flow gas hot water systems use electricity for ignition and electronic controls. The electrical requirements and installation position should be checked during the site assessment.
Can water-temperature controllers be installed?
The Infinity B26 is compatible with selected Rinnai hot water controllers. Controller suitability, quantity and positioning should be confirmed when the system is quoted.
How much does Rinnai B26 installation cost in Sydney?
The price depends on the property, product configuration, gas-line capacity, pipework, electrical access, removal of the old system and any required compliance work. Call 0450 330 622 for a personalised quotation.
