The WPL-A Premium air source heat pump is not only suitable for heating and hot water but also provides cooling in the summer months. Since the inverter unit achieves high flow temperatures even at very low outside temperatures of down to –25 °C, it is equally suitable for use in new build and renovation projects. The WPL-A HK Premium contains a future-proof refrigerant. In combination with its high efficiency, the heat pump scores highly as an environmentally responsible heating technology.

Quick overview

  • Air source heat pump for heating, hot water and cooling
  • Inverter technology provides adjusted heating output
  • High flow temperatures of up to 75 °C enable high DHW temperatures and mixed water volumes
  • Low operating costs through high efficiency all year round
  • Smart Grid ready for connection to solar PV and energy management systems

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.

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.

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 -25°C.
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.
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.
