Heat Pumps Comparable to the principle of a refrigerator, the heat pump function is simplicity itself: It withdraws latent energy from air, water or ground and transfers it to the heating system. This free envirnmental energy is initially routed to the heat exchanger (evaporator) of the heat pump. The evaporator contains the liquid refrigerant (process medium), which absorbs the heat from the energy source and, in the process, evaporates. The compressor pulls the gaseous process medium inside where it is compressed. As pressure rises, the temperature increases. A second heat exchanger (condenser) the ensures that the heat is transfered to the heating circuit. the expansion valve finally provides the pressure reduction, and the cycle starts again.

That's how free energy from the environment is converted into useful heat.

Fossil Fuels

Time for contemplation: It seems that we have forgotten how to handle the treasures of this world with care. We are only stewards or guardians of the world for future generations.

Reduce emissions, protect resources: The combustion of fossil fuels such as natural gas or fuel oil produce emissions, amongst them, carbon dioxide, which is partially responsible for environmental damage. The substantial increase in other combustion residues also gives rise to concern, as the global warming it causes disturbs the sensitive climate balance.

Heat pump technology makes an important contribution to environmental protection.

Air/Water In spite of their high output, WPL series air/water heat pumps require suprisingly little space. The new powerful scroll compressor provides cost-effective heat all year round. It delivers substantially greater efficiency and ensures exeplary performance factors plus excellent heating output. Even in winter, when it really matters. Energy costs can be further reduced when combining the heat pump with solar heating system.

Bore Hole / Brine Water Compact WPF 5.13 SOL heat pumps represent an intelligent system, which utilises free energy from the environment and additional solar energy for the production of domestic hot water (DHW) and to backup cenral heating.

Thanks to its outstanding sound insulation, it does not need to be banished to the cellar, but can be installed in a hobby or utility room instead. The new high performance refrigerant, R410A, also makes no demands on ventilation.

The WPF models already include almost all functional elements for your heating system. The attractively designed casing houses the diverter valve for DHW loading, the immersion heater element, the WPM control unit and much more.

Water / Water Optimum utilisation of groundwater energy

The four sizes of WPF heating system heat pumps cover every demand for detached and two-family homes.

The WPF delivers exeplary performance - not only in brine/water, but also in water/water operations.
