Product Details
STIEBEL ELTRON's next generation WPL-A Trend air source heat pump series delivers year-round comfort with efficient heating, domestic hot water, and summer cooling. Its advanced inverter technology ensures high flow temperatures even at extremely low outdoor temperatures, while operating sound is minimized thanks to an encapsulated refrigerant circuit and acoustically isolated compressor. Using the eco-friendly R290 refrigerant, the WPL-A Trend series combines high efficiency with minimal environmental impact, making it ideal for both new builds and renovation projects.
The WPL-A range will include the WPL-A 10.2 (10.97 kW) and WPL-A 13.2 (13.92 kW) models, which will be available soon, and the larger WPL-A 17.2, coming later. STIEBEL hydronic heat pumps can be used in combination with optional accessories, such as the ISG connect unit, which allows control of the heat pump remotely from your home network or mobile device.
STIEBEL ELTRON is a pioneer in home energy management: all hydronic heat pump models can be connected to a solar PV system. Furthermore, they can be integrated into a SmartGrid, increasing self-consumption and reducing energy bills.

FAQ
Air source heat pumps use a refrigeration circuit to harvest energy from the air. This energy is then used to heat the water which is pumped through a hydronic heating circuit, such as in-slab piping or radiators, to warm your home.
Hydronic heat pumps from STIEBEL ELTRON are the quietest on the market thanks to an encapsulated refrigerant circuit and acoustically isolated compressor. Advanced sound engineering guarantees that heat pumps from STIEBEL ELTRON can be used in neighbourhoods with a dense population. Many models even feature an additional silent mode.
Yes, hydronic heat pumps from STIEBEL ELTRON are engineered to operate energy efficiently even when outside temperatures fall below zero. Advanced technology ensures efficiency even at cold temperatures down to -20°C. For instance, the natural defrost function of the WPL 25 AC(S) comes into play in temperatures around 0°C to ensure a smooth and efficient operation when it becomes frosty in Australian winter.
Yes, STIEBEL ELTON offers a wide range of hydronic heat pumps which serve as heat source for either under floor heating or radiator heating, or both. This depends on the models' flow temperatures. Please consult with a STIEBEL expert to identify the right system for your needs.
STIEBEL ELTRON is working closely with hydronic heating specialists throughout Australia. Feel free to get in touch and ask for a recommended installer.
STIEBEL ELTRON offers both single and three phase models. The letter S in the model description stands for single phase, such as the WPL 25 ACS. Please also check the technical details on the product page of your model or contact STIEBEL ELTRON for further advice.
All STIEBEL ELTRON heat pumps in Australia are offered with an optional ISG web, which allows you to control and monitor your heating system via a home network or mobile device.
