Buy the Rheem AmbiPower 280e 2.4kW Hardwired Heat Pump Hot Water System online from Hot Water Outlet, with fast delivery available across Australia and same day delivery available in select metro areas on eligible orders.

The Rheem AmbiPower 280e hardwired model is a larger-capacity 280L heat pump hot water system designed for households wanting efficient electric hot water with stronger backup element support than the 10 amp plug-in version. It uses heat from the surrounding air to warm stored water, helping reduce reliance on direct electric element heating compared with a standard electric storage hot water system.

With 280L capacity, R290 natural refrigerant, a 2.4kW hardwired backup element, touch screen LED controls and suitability for up to 6 people under Rheem’s stated usage assumptions, the AmbiPower 280e is a strong option for family homes, larger townhouses, rental properties and customers upgrading from an older electric storage hot water system.

About the Rheem AmbiPower 280e Heat Pump

The Rheem AmbiPower 280e is part of Rheem’s AmbiPower heat pump hot water range. Instead of relying only on a traditional electric heating element, it uses heat pump technology to draw heat from the surrounding air and transfer that heat into the stored water.

Unlike roof-mounted solar hot water, the AmbiPower 280e does not rely on direct sunlight or solar collectors to heat water. This makes it a practical option for customers who want an efficient storage hot water system without needing roof space for solar hot water panels.

This product is the 2.4kW hardwired version, which is designed for properties with a suitable hardwired electrical connection or where a licensed electrician can provide the correct connection.

Buy Rheem AmbiPower 280e Supply Only

2.4kW Hardwired Backup Element

The Rheem AmbiPower 280e hardwired model includes a 2.4kW backup element.

This is different from the 10 amp plug-in version, which uses a 1.5kW backup element. The larger backup element can provide stronger boost and emergency heating support when higher hot water demand occurs, when recovery support is needed, or when operating conditions are less favourable for heat pump-only heating.

A licensed electrician should confirm the electrical setup before installation. Do not assume an existing power point, circuit or wiring arrangement will suit the hardwired model.

Hardwired Model vs Plug-In Model

The Rheem AmbiPower 280e range includes both hardwired and plug-in options.

The hardwired model uses a 2.4kW backup element and requires a suitable hardwired electrical connection.

The plug-in version uses a 10 amp plug and lead connection with a 1.5kW backup element.

The right option depends on your property, electrical setup, recovery needs, installer advice and whether you want a hardwired or plug-in heat pump hot water system.

For customers specifically wanting the stronger backup element version, this 2.4kW hardwired model is the correct option to compare.

Lower Energy Hot Water

The Rheem AmbiPower 280e is designed to reduce water heating energy use compared with a standard electric water heater.

Heat pump technology works by absorbing heat from the surrounding air and transferring that heat into the stored water. This allows the system to heat water efficiently without relying only on direct electric element heating.

Rheem lists potential water heating energy savings of up to 73.9% in Zone 3 when replacing an electric water heater under stated conditions. Actual savings can vary depending on location, the system being replaced, hot water use, tariff setup, household habits, solar PV use and installation conditions.

R290 Natural Refrigerant

The Rheem AmbiPower 280e uses R290 natural refrigerant.

Rheem lists the refrigerant with a GWP of under 3, making the AmbiPower 280e a strong option for customers comparing modern heat pump hot water technology with lower-impact refrigerant design.

Advanced Wraparound Microchannel Heating

The AmbiPower 280e uses advanced wraparound microchannel heating technology designed to support uniform and faster water heating.

This design helps transfer heat into the stored water and supports recovery performance for households with regular daily hot water demand.

Built for Australian Conditions

The Rheem AmbiPower 280e is designed for Australian conditions, with features intended to support outdoor heat pump use where the location is suitable.

The system includes an enamel lined water tank, side fan design, painted sheet metal outer shell and aluminium top cover.

Like all heat pump systems, placement matters. The unit needs suitable airflow, access, drainage and clearances. Before ordering, confirm the proposed location with your licensed installer.

Touch Screen LED Display

The Rheem AmbiPower 280e includes a touch screen LED display.

This gives the homeowner better visibility over system operation and performance compared with older-style storage hot water systems.

Suitable for Cold and Harsh Conditions

Rheem lists the AmbiPower 280e as suitable for cold climates with an operating range from -6°C to +43°C.

It is also listed as suitable for harsh water conditions, making it a practical option for a wide range of Australian homes where climate and water quality need to be considered.

STCs, Rebates and Incentives

The Rheem AmbiPower 280e may be eligible for Small-scale Technology Certificates where requirements are met. Additional state-based incentives may also apply in some areas.

Rebates, STCs and incentive values can change. Eligibility may depend on the product model, installation location, installer requirements, installation date, program rules and whether the installation is completed by an approved provider.

Confirm current eligibility before ordering if rebates or incentives are important to your purchase decision.

Common Uses

The Rheem AmbiPower 280e 2.4kW Hardwired Heat Pump may suit:

Electric hot water system replacement

Check whether your installer requires:

Tempering valve
PTR valve
Pressure limiting valve
Expansion control valve
Isolation valves
Non-return valve
Duo valve
Hot water connection kit
Copper or braided connections where suitable
Pipework fittings
Drainage parts
Base or support requirements
Insulation or weather protection accessories

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.
