The Rheem 26L Natural Gas 50°C continuous flow water heater is a higher-capacity gas hot water system designed for medium to larger homes, apartments, townhouses and replacement jobs where a storage tank is not ideal. With 26 L/min continuous hot water delivery at a 25°C rise, a 6-star energy rating, 50°C factory temperature-limited output and compact wall-mounted design, it is a strong option for customers wanting reliable natural gas hot water for around 2 to 2.5 bathrooms where site conditions are suitable.

About the Rheem 26L Natural Gas Continuous Flow Water Heater

The Rheem 26L Natural Gas Continuous Flow Water Heater is part of Rheem’s gas continuous flow hot water range. It heats water only when hot water is needed, rather than storing a full tank of heated water.

This makes it a practical option for homes where outdoor space is limited, where a wall-mounted gas unit is preferred, or where the existing setup already suits an outdoor natural gas continuous flow hot water replacement.

The 26L model provides more flow capacity than the Rheem 16L and 20L models, making it better suited to homes with higher hot water demand. It is commonly selected for medium to larger households, larger apartments, townhouses and family homes where multiple outlets may be used more often.

This is the natural gas version. Natural gas and LPG models are not interchangeable, so the correct gas type must be selected before ordering or installation.

Higher Flow Continuous Hot Water

The Rheem 26L Natural Gas continuous flow water heater is designed for homes needing stronger flow capacity than smaller continuous flow models.

With 26 L/min hot water delivery at a 25°C rise, this model can suit medium to larger households where multiple fixtures may be used more often. Actual performance depends on incoming water temperature, gas supply, water pressure, pipe sizing, fixture flow rates and household demand.

Compact Outdoor Design

The Rheem 26L Natural Gas is designed to save space compared with a traditional gas storage hot water system.

Because it heats water on demand, it does not require a large storage cylinder. The compact body can be mounted outdoors on a suitable wall, making it useful for homes with limited outdoor space, narrow side access, townhouses, units and medium to larger replacement locations.

50°C Temperature-Limited Output

This model is the 50°C factory temperature-limited version. A 50°C model can be a practical option for domestic hot water installations where safer outlet temperature control is important.

Some applications may still require additional tempering or installation controls depending on the property, plumbing layout, fixtures and compliance requirements. Suitability should be confirmed before installation.

Natural Gas Hot Water

This product is the natural gas version of the Rheem 26L continuous flow water heater.

It is intended for homes connected to natural gas. It is not the same as the LPG version, and the two gas types cannot be swapped without selecting the correct product and completing suitable licensed gas work.

Customers should confirm their gas type before ordering.

Rheem Q Factor™ and Flamesafe® Protection

The Rheem 26L Natural Gas includes Rheem Q Factor™ technology designed to help deliver steady hot water temperature and reduce the fluctuations that can occur with some continuous flow systems when hot water demand changes.

It also includes Flamesafe® overheat protection, which is designed to shut down the water heater before overheating can occur.

Common Uses

The Rheem 26L Natural Gas 50°C Continuous Flow Hot Water System can be suitable for:

• natural gas hot water replacement

• outdoor continuous flow hot water applications

• homes connected to natural gas

• medium to larger apartments

• townhouses

• family homes

• rental properties

• compact wall-mounted replacement locations

• homes with around 2 to 2.5 bathrooms depending on demand

Tempering Valve and Element Information

*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.

If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.

Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.

Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.

1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.

This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.

Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.

**Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.

A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.

If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.

If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.

Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.

It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
