Its quiet operation is a defining feature of the Stiebel Eltron WWK302H Heat Pump. The heat pump utilizes advanced acoustic separation technology, maintaining an average sound pressure level of 45 dB(A) at 1m distance in free field conditions.

This low noise level is largely attributable to the heat pump’s encased compressor design suitable for significantly reducing operational noise. The company also encourages reading the operating and installation guide to consider the positioning of the heat pump to further minimize noise.

Solar PV Compatibility

The WWK302H heat pump impressively supports integration with solar PV systems. It can be connected to solar PV systems, allowing it to strategically raise the tank temperature using excess solar energy when signaled by the solar PV inverter.

Featuring a smart element, the heat pump can heat approximately the top 80 litres of the tank with a 1.7 kW element, optimizing the use of available solar power during periods of high hot water demand. Additionally, the heat pump can be networked with solar PV and energy management tools, creating smart systems that maximize on-site consumption of solar power.

Installation Options and Requirements

The Stiebel Eltron WWK302H Heat Pump caters to a range of installation settings, each with its unique requirements. It’s designed with a smart element situated at the top of the hot water cylinder, which activates during high hot water demand to assist with heating approximately the top 80 liters.

The heat pump, designed for cold climates, operates efficiently and safely in cold water temperature as low as -5°C, thanks to its installation active defrost function.

Indoor vs Outdoor Installation

The WWK302H heat pump is designed specifically for installation outdoor in Australia, but it can be installed either indoors or outdoors, offering flexibility in installation choices. For an indoor installation, it is necessary to have a clear space of at least 13 m^3 to ensure efficient diffusion of cold air from the refrigeration system. This allows for proper functioning and maintenance of the system.

With a tank capacity of 302 liters, the heat pump operates efficiently in a wide range of temperatures from -5°C to +42°C, making it suitable for a diverse range of climate conditions and maintaining an optimal c air flow rate.

Electrical Installation and Safety

Electrical installation for the WWK302H heat pump must adhere to AS/NZS3000 wiring rules and AS/NZS3500.4.2 installation requirements to ensure compliance and safety. The heat pump operates on a 240V supply and has a current draw of 2.3 Amps, with a rated connection requirement of 10 Amps.

The heat pump also has an IP24 ingress protection, indicating a level of protection against solid objects larger than 12mm and splashing water, contributing to its safety features. A thorough inspection of all equipment and connections is recommended after installation and before switching on power to ensure everything is functioning correctly.

Maintenance and Anode Technology

The WWK302H heat pump has been designed with maintenance considerations to ensure long-term reliability and optimal performance. Regular monthly checks are recommended for the condensate drain and pan to prevent blockages that can affect the system’s operation.

The maintenance-free current impressed anode eliminates the need for regular anode replacement. It also reduces overall maintenance requirements.

Maintenance Schedule

For the Stiebel Eltron WWK302H heat pump to perform optimally and last longer, regular maintenance is indispensable. One key aspect of this maintenance schedule involves inspecting the condensate drain and the top of the condensate pan at least once a month to ensure there are no blockages from debris.

Following this maintenance schedule not only ensures the efficient operation of the heat pump but also significantly prolongs its lifespan. It’s a small time investment that results in long-term benefits.

Maintenance-Free Anode

The maintenance-free current impressed anode of the WWK302H heat pump deserves special attention. Unlike traditional sacrificial anodes that require regular replacement or manual maintenance, the maintenance-free anode utilizes a current impressed method.
