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.

Pre-requisites for the water/water operation are two wells (delivery and return wells) and ground water in adequate quantity and quality.

The energy is transfered to the heating water via the heat exchanger and is utilised to optimum benefit. Subject to heat demand, the heating water can be raised to between 15 Degrees C and 60 Degrees C. The groundwater temperature remains relatively constant, even in harsh winters.

At a glance:

• Four sizes for detached and two-family homes
• Energy source: Groundwater
• Application Range +7 to +20 Degrees C water temperature
• For automatically raising heating water upto + 60 Degrees C over the entire output range
• Suitable for all operating modes
• Extremely quiet operation
• High annual performance factor
• Including integral solar and cenral heating control

Water / Water Heat Pump

Your choice: Ground probe or ground collector

Over the course of a year upi gain the highest energy yeild with water/water heat pump.

The main reason for this is the fact that the groundwater temperature remains at a constant level, which is high for heat pumps, i.e. between 8 Degrees & 12 Degree C all year round.

When utilising the energy source, the heat pump will generate more than five parts heating energy from one part input power.

How it Works:

The water/water heat pump requires two well holes (delivery and return well). Warm groundwater is extracted from the delivery well and cooled down as low as 5 Degrees C. Afterwards it is reintroduced into the groundwater via the return well. The energy extracted from the ground water (upto 80%) can cover nearly 100% of your heating requirements for a full 12 months of year.
