Rinnai Infinity B26 LPG Continuous Flow Hot Water System

The Rinnai Infinity B26 LPG Continuous Flow Hot Water System is available from Installed Today as a supply-only LPG gas hot water unit or as a complete supply and install package in selected Brisbane and Gold Coast service areas, where available.

Choose the unit only if you already have a licensed gas fitter arranged, or check your supply and install package before checkout to confirm LPG suitability, gas supply requirements, valve kit requirements, access, water pressure, electrical connection, outdoor location and available installation timeframes.

The Rinnai Infinity B26 LPG is a high-capacity external gas continuous flow hot water system designed for homes that need stronger on-demand hot water performance without a storage tank. With a 26 L/min flow rate, a 6.0 Star Equivalent Energy Rating and Puretemp™ temperature stability technology, it is a strong option for larger LPG properties, family homes and replacement installations needing reliable hot water from a compact wall-mounted unit.

About the Rinnai Infinity B26 LPG

The Rinnai Infinity B26 LPG heats water as it passes through the unit, instead of storing hot water in a cylinder. This gives the home continuous hot water while the unit has suitable LPG supply, water flow and power available.

This model is designed for LPG only. It is not interchangeable with natural gas unless the correct natural gas model is selected. The LPG version is commonly suited to homes using bottled LPG or existing LPG infrastructure, subject to gas supply sizing, regulator suitability and licensed gas fitting checks.

The B26 is generally suited to 2 bathroom homes and may suit 1 to 3 shower outlets in warmer climates depending on water temperature, fixture flow rates, usage patterns and site conditions.

LPG Continuous Flow Hot Water

The Rinnai Infinity B26 LPG is designed for homes using LPG gas. It may suit properties without mains natural gas, larger homes using bottled LPG, acreage properties, granny flats, secondary dwellings and homes replacing an older LPG continuous flow system.

Because this is the LPG model, it must be matched to a suitable LPG supply. LPG and natural gas appliances are not interchangeable, so the correct gas type must be selected before ordering and installation.

Continuous Flow Performance

The B26 heats water on demand when a hot tap is opened. This means there is no stored hot water cylinder and no tank capacity to recover after use.

Its 26 L/min flow rate makes it a stronger choice than smaller continuous flow models where the home needs more hot water capacity. Actual performance depends on incoming water temperature, selected outlet temperature, pipework, fixture flow rates, LPG supply and whether multiple outlets are used at the same time.

Energy Rating

The Rinnai Infinity B26 LPG has a 6.0 Star Equivalent Energy Rating. Continuous flow systems can be efficient because they heat water only when required, helping reduce standby heat loss compared with many storage tank systems.

Running costs still depend on household usage, LPG pricing, outlet temperature, incoming water temperature, fixture flow rates and installation setup.

Puretemp™ Temperature Stability Technology

Puretemp™ temperature stability technology helps maintain steadier hot water temperature during normal operation. This is useful for households wanting more consistent hot water delivery from a larger LPG continuous flow system.

Site conditions, fixture flow rates, gas supply and correct installation still play an important role in the final hot water performance.

Compact Outdoor Design

The Rinnai Infinity B26 LPG has a compact wall-mounted design, making it suitable for external installation where a large storage tank is not wanted or where space is limited.

The final position must comply with clearance, access, flue terminal, drainage, gas, plumbing and electrical requirements.

No Stored Tank

Because the B26 is a continuous flow system, it does not store hot water in a cylinder. This helps save space and makes it suitable for homes wanting an external wall-mounted hot water replacement.

There is no tank capacity to size, but the flow rate must suit the home’s hot water demand.

Optional Hot Water Controllers

The Rinnai Infinity B26 LPG is compatible with optional Rinnai hot water controllers. Controllers can provide added convenience and temperature control where suitable.

Controllers are not included unless selected separately. Installation suitability and controller compatibility should be checked before purchase.

Outdoor Installation Only

This Rinnai Infinity B26 LPG model is for external outdoor installation. Do not install this unit internally unless a manufacturer-approved internal or flued model is specifically selected for that purpose.

Outdoor installation must still meet clearance, ventilation, flue terminal, gas, plumbing and electrical requirements.

Water Pressure Requirements

The Rinnai Infinity B26 LPG requires a minimum water pressure of 200 kPa and has a maximum listed water pressure of 1000 kPa.

If the property has high water pressure, pressure control may be required. If water pressure is too low, the unit may not operate correctly. Pressure should be checked as part of the installation assessment.

Gas Supply Requirements

The LPG gas supply must be suitable for the appliance demand. The B26 has an LPG gas rate range of 16–199 MJ/h.

A licensed gas fitter should confirm LPG bottle setup, regulator suitability, gas pipe sizing, appliance location and compliance requirements before installation.

Electrical Requirement

The Rinnai Infinity B26 LPG requires power for operation and has a listed electrical consumption of 68 W.

Electrical access must be suitable for the installation location. Electrical work is not included unless selected or arranged separately.

Rinnai Infinity B20 vs B26 LPG

The Rinnai Infinity B26 LPG is the larger option compared with the B20 LPG and may suit homes needing more hot water flow capacity.

The B20 is generally suited to smaller homes or lower hot water demand. The B26 provides a higher 26 L/min flow rate, making it a stronger option for larger homes, 2 bathroom properties or households that need better performance when hot water demand is higher.

The right size depends on bathrooms, shower flow rates, incoming water temperature, number of users, LPG supply and whether multiple outlets are used at once.

Rinnai Infinity B26 vs INF28 Internal

The Rinnai Infinity B26 LPG is an external continuous flow model designed for outdoor installation. The INF28 Internal is a different model type designed for internal applications where a manufacturer-approved internal unit is required.

Do not use the B26 for internal installation. If the hot water system needs to be installed indoors, the correct internal or flued model must be selected and installed to manufacturer and compliance requirements.

Common Uses

• LPG continuous flow hot water replacement

• External gas hot water system replacement

• 2 bathroom homes

• Larger family homes

• Townhouses

• Rental properties

• Investment properties

• Renovation projects

• Homes using bottled LPG

• Homes needing stronger hot water flow than a smaller continuous flow unit

• Supply-only orders where a licensed installer is already arranged

• Supply and install orders in selected Brisbane and Gold Coast areas

Suitability depends on household size, hot water usage, LPG supply, water pressure, electrical access, installation location, plumbing condition, outlet flow rates, clearances and compliance requirements.
