WPL 25 AC / WPL 25 ACS

Enjoy comfortable warmth in your home during the chilly winter months thanks to the WPL 25 AC(S) range of air source hydronic heat pumps from STIEBEL ELTRON. Heating your home with energy harvested from the air, hydronic heating is a cost-effective way to keep your home warm and cosy. Designed for outdoor installation in Australian conditions, the WPL 25 AC and WPL 25 ACS systems is a perfect start for the transition from fossil fuels to renewable energies in your home.

As nearly 40% of energy consumed in Australian homes is used for heating and cooling, it makes perfect sense to install an energy-efficient appliance and reduce the ongoing cost of your heating system tremendously.

Details

STIEBEL ELTRON’s efficient inverter technology allows the WPL 25 AC(S) to offer an exceptionally high COP of 5, while the operating sound is kept to a minimum thanks to an encapsulated refrigerant circuit and acoustically isolated compressor. Through enhanced saturated vapour injection, high flow temperatures of up to 65°C can be achieved, making the WPL 25 AC(S) the perfect heat source for in-slab and radiator heating purposes.

The WPL 25 AC(S) range is available in both single (ACS) and 3 phase (AC) variants. STIEBEL hydronic heat pumps can be used in combination with optional accessories, such as the ISG web unit which allows control of the heat pump remotely from your home network or mobile device.

STIEBEL ELTRON is a pioneer in the field of home energy management: all hydronic heat pump models can be connected to a solar PV system. Furthermore, they can be integrated into a so-called SmartGrid. Both options increase self-consumption and reduce energy bills.

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.

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.
