NDW®

Heat source ground water

The NDW® heat pump from NEURA unites highest efficiency with environmentally friendly operation. If you have ground water at an appropriate depth and in the right amount, you may then use this wonderful heat source.

The temperature always lies between 7 and 12 °C. Thanks to the low space requirement, the NEURA NDW® ground water heat pump is best suited also for small plots of land.

Highest efficiency even in a small garden

Thanks to the constant temperature of ground water you can obtain best performance with the NEURA NDW ground water thermal heat pump even during the lowest outside temperatures. The two wells require little room and thus are perfect for small plots of land. If you have no technical room or if you want to use the existing space for a different purpose, then you can also install the thermal heat pump outside at the well system.

Individual adjustment - heating or cooling

Thanks to the NEURA NDW ground water thermal heat pump you can not only generate heat. The heat pump may also be used for cooling, in order to create in the Summer a nice atmosphere in the house. The cooling takes place via the 'heating system'. The warmth taken from the rooms is transferred via the heat pump back to the ground water.

Why it makes your life more comfortable:

  • Highest efficiency even during periods of very low outside temperatures
  • Operates year-round - heating and cooling
  • Installation outside or inside
  • Low space requirements

Highest efficiency - highest output

Thanks to the NDW high performance pump the operational costs are greatly reduced, and the economy increased. Thanks to the adjustment of rotation speed of the pump one can reach top performance at the same time using only as little as one really needs.

Quiet, vibration-free operation

Thanks to the insulated housing one can guarantee very quiet and calm operation. Furthermore, the underside of the thermal heat pump sports rubber buffers prohibiting the transfer of vibrations to the building.

Why does this make your life more comfortable:

  • Constant temperature of the soil all year round
  • No excessive noise thanks to insulated housing

What does the COP value or the performance coefficient tell us?

COP stands for Coefficient of Performance. A COP informs of the effectiveness of a thermal heat pump. The higher the COP, the more energy may be produced from 1 kW of electric power. The COP is sometimes called the performance coefficient.

 

Example: In the case of a COP of 5 one can get 5 kW of heating power from 1 kW of electric power used.

 

How much ground water is required?

A precise calculation will be conducted by a NEURA employee, and will fit your requirements exactly. A rule of thumb says: approx. 300 to 400 litres per hour.

What is a suction well?

A suction well is the well from which the ground water for the thermal heat pump is taken (or 'sucked').

What is an injection well?

The injection well is the well through which the cooled ground water is returned to the soil. At your choice instead of an injection well a soakaway may also be used.

How deep must the drilling reach in order to be able to obtain ground water?

This varies from region to region. In order to be able to determine the exact ground water level a trial drilling must be executed. Often this information can be obtained from the commune authorities. Sometimes values obtained from experience by the neighbours, who had already installed a thermal heat pump, may be used.

What are the available modes of operation?

Monovalent: The thermal heat pump is planned so that it can cover the entire heating requirements of the house.

Bivalent, alternative: The thermal heat pump operates to a specific outside temperature, and afterwards switches off. The required remaining heat is then generated from an additional source (electric heating element, wood-burning boiler, etc.)

 

Bivalent, parallel: The thermal heat pump operates to a specific outside temperature alone, and afterwards switches an additional heat source on, in order to cover the entire requirements of the house or building.
