Stiebel Eltron WWK 302H 302L Heat Pump Hot Water System

The Stiebel Eltron WWK 302H 302L Heat Pump Hot Water System is available from Installed Today as a supply-only heat pump 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 plumber and electrician arranged, or check your supply and install package before checkout to confirm installation suitability, access, airflow clearances, drainage, water pressure, electrical requirements, valve kit requirements and available installation timeframes.

The Stiebel Eltron WWK 302H is the larger H-model version in the WWK heat pump range, meaning it combines a 302L cylinder with a 1.7 kW smart element to assist hot water recovery during higher hot water use. With active defrost, solar PV compatibility, quiet encased compressor operation and a maintenance-free impressed current anode, it is a strong option for larger households wanting an efficient heat pump hot water system with added recovery support.

About the Stiebel Eltron WWK 302H 302L

The Stiebel Eltron WWK 302H uses heat pump technology to draw heat from the surrounding air and transfer it into stored hot water. This helps reduce reliance on direct electric heating compared with a standard electric storage hot water system.

The 302L capacity may suit larger households, family homes, higher hot water usage properties and homes wanting more stored capacity than the WWK 222H, depending on shower flow rates, recovery expectations, tariff setup, climate and installation conditions.

The key difference with the WWK 302H is the built-in 1.7 kW smart element. This element assists the heat pump when a high volume of hot water has been drawn from the tank, helping heat approximately the top 80 litres of stored water for improved recovery support.

Heat Pump Storage Hot Water

The Stiebel Eltron WWK 302H stores hot water in a 302L cylinder and uses heat pump technology to heat the water efficiently.

Instead of relying only on a standard electric element as the main heating method, the WWK 302H uses surrounding air as the main heat source. This makes it a strong option for homes wanting to upgrade from a conventional electric storage hot water system where the site is suitable.

H-Model Smart Element

The WWK 302H includes a 1.7 kW smart element positioned in the top of the cylinder. This is the main difference between the WWK 302H and the standard WWK 302.

When a high volume of hot water is drawn from the tank, the smart element can assist the heat pump by heating approximately the top 80 litres. This helps support recovery during heavier hot water use.

Efficient Heat Pump Hot Water

The WWK 302H has a listed seasonal COP of 3.58. COP is a performance measure that compares heat output to electrical input under test conditions.

Real-world performance depends on ambient temperature, hot water usage, installation location, airflow, settings, tariff setup and household demand.

Active Defrost Function

The Stiebel Eltron WWK 302H includes active defrost to support heat pump operation in colder conditions.

When frost is detected at the evaporator, the active defrost function helps remove frost build-up so the system can return to normal hot water generation. This supports operation down to -5°C.

Maintenance-Free Impressed Current Anode

The WWK 302H uses a maintenance-free impressed current anode, making it suitable for hard or soft water areas.

Unlike sacrificial anodes that are designed to wear away over time, an impressed current anode is designed to provide corrosion protection without regular anode replacement under normal conditions.

Enamelled Steel Cylinder

The WWK 302H uses an enamelled steel cylinder. The cylinder is designed for domestic hot water storage and works with the impressed current anode for long service life.

Water quality, pressure control, correct installation and ongoing maintenance all play a role in long-term system performance.

Solar PV Compatibility

The Stiebel Eltron WWK 302H is compatible with solar PV integration where configured correctly.

A solar PV signal can allow the unit to increase tank temperature during peak solar production, helping make better use of self-generated power where the home has a suitable solar setup.

Solar PV integration depends on the electrical setup, inverter capability, system configuration and installer requirements.

Off-Peak Operation Option

The WWK 302H can operate on off-peak power where available.

This may suit homes wanting to manage hot water running times around tariff windows, solar production or household usage patterns. Actual running costs depend on energy rates, settings, hot water demand and installation conditions.

Low Heat Pump Power Consumption

The WWK 302H has a listed heat pump power consumption of 0.55 kW. The H-model smart element is separately listed at 1.7 kW.

Electrical work must still be completed to Australian standards, and site suitability should be checked before installation.

Indoor or Outdoor Installation

The Stiebel Eltron WWK 302H can be installed indoors or outdoors where suitable.

Indoor installation requires a clear space of 13m³ so the cold air from the refrigeration system can diffuse. Outdoor installation requires 500 mm clearance either side of the grille, along with suitable drainage, access, base support and weather exposure conditions.

Quiet Encased Compressor

The WWK 302H is designed with an encased compressor to help reduce operating noise.

It has a listed sound pressure level of 45 dB(A) at 1 m. Noise impact still depends on the installation location, surrounding walls, nearby bedrooms, fences, reflective surfaces and local site conditions.

Water Pressure and PLV Requirements

The WWK 302H has a listed maximum permissible operating pressure of 850 kPa.

Water pressure must be checked before installation. A pressure limiting valve may be required depending on the property’s incoming water pressure, the selected valve kit and the installation requirements.

High water pressure, missing valves or non-compliant existing pipework can affect installation scope and final cost.

Drainage and Condensate Requirements

Heat pumps produce condensate during normal operation. The installation location must allow suitable condensate drainage in addition to standard hot water system safety valve discharge requirements.

Drainage changes are not included unless selected or arranged as part of the installation package.

Clearance Requirements

Correct airflow is important for heat pump performance. The WWK 302H needs suitable installation clearance so the unit can draw and discharge air properly.

Poor airflow, tight enclosures, blocked grilles or unsuitable indoor spaces can reduce performance and may make the installation unsuitable.

STCs and Government Incentives

Heat pump hot water systems may be eligible for STCs or government incentives depending on the product, installation date, location and program rules.

Eligibility, rebate value and availability can change. Any incentive should be checked before purchase and should not be treated as guaranteed unless confirmed as part of the checkout or installation process.

WWK 302 vs WWK 302H

The WWK 302 is the standard 302L heat pump model. The WWK 302H is the H-model version with a 1.7 kW smart element.

The WWK 302H may be the better option where the household wants additional recovery support during higher hot water use. The standard WWK 302 may suit customers who specifically want the non-H model and do not need the smart element feature.

WWK 222H vs WWK 302H

The WWK 222H has a 220L cylinder capacity and can deliver up to 360L of 40°C shower temperature water at 20°C cold water temperature.

The WWK 302H has a larger 302L cylinder capacity and can deliver up to 540L of 40°C shower temperature water at 20°C cold water temperature.

The WWK 302H may be more suitable for larger households, higher hot water demand or homes wanting more stored capacity while still keeping the H-model smart element feature.

WWK 302H vs Standard Electric Storage

A standard electric storage system uses an electric element to heat water directly. The Stiebel Eltron WWK 302H uses heat pump technology to draw heat from the surrounding air, with a 1.7 kW smart element available to assist recovery during higher usage.

The WWK 302H may be a better option for customers wanting an energy-efficient electric hot water upgrade, solar PV compatibility and stronger recovery support than a heat pump-only model. A standard electric storage system may still suit customers wanting a simpler lower upfront cost replacement where heat pump space, airflow, noise, drainage or electrical requirements are not suitable.
