FAQ

1. How does a hydronic heat pump work to heat my home?

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.

2. How noisy is a hydronic heat pump?

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.

3. Can a hydronic heat pump system still heat my home when it is cold outside?

Yes, hydronic heat pumps from STIEBEL ELTRON are engineered to operate energy efficiently even when outside temperatures fall below zero. Advanced technology from Germany 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.

4. Can I use hydronic radiators with this heat pump?

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.

5. Where can I purchase a STIEBEL ELTRON hydronic heating heat pump from?

STIEBEL ELTRON is working closely with hydronic heating specialists throughout Australia. Feel free to get in touch and ask for a recommended installer.

6. Do I need three phase power to operate a hydronic heating heat pump?

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.

7. Can I control my hydronic heating heat pump from my mobile device?

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.
