Compact 480mm Diameter

The Rheem 125L Electric Water Heater has a small 480mm diameter, making it a useful option for selected replacement jobs where installation space is limited.

This can help in tight external corners, narrow side access areas, compact service spaces and replacement locations where a wider electric storage system may be harder to fit.

Rheem Ultranamel® Cylinder Protection

The Rheem 125L uses Rheem Ultranamel® cylinder coating. This tough internal coating is designed to help protect the cylinder and support long-term performance when the unit is correctly installed, selected and maintained.

Water quality, installation compliance, valve setup and servicing conditions can all affect hot water system lifespan and warranty outcomes.

Dual Handed Connections

The Rheem 125L Electric Water Heater includes dual handed inlet and outlet fittings. This can make replacement installation easier because the water connections can better suit different existing plumbing layouts.

Dual handed connections can be especially helpful in like-for-like replacement jobs, where matching existing pipework may reduce the need for extra plumbing changes.

The Rheem 125L Electric Hot Water System can be suitable for:

• Smaller homes

• Units and apartments

• Townhouses

• Granny flats

• Rental properties

• Compact replacement locations

• Electric storage hot water replacement

• Homes with up to 4 people under Rheem’s stated usage assumptions

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.
