NDX®
Heat source ground
The 'D' in 'NDX' stands for 'direct', and is the most ground-breaking method of using the heat of the ground efficiently. Directly and without any diversions for maximum effect.
Highlights:
NDB®
Heat source deep drilling
The deep drilling technology offers the optimum solution of an excellent heat source especially in the event of small space availability.
Highlights:
NDW®
Heat source ground water
Thanks to the NEURA NDW ground water thermal heat pump you can use an energy source that especially useful in small gardens in order to achieve highest efficiency - 365 days of the year

Hot water solutions
Home-made energy - Warmth free of charge
The hot water heat pumps from NEURA
utilise the hidden sources of energy of your house
as a free supply of warmth.
Highlights:
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.
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.
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.
| Heat pump type | W6 EuC | W6 EuC | W10 EuC | W10 EuC | W18 EuC | W20 EuC | |
|---|---|---|---|---|---|---|---|
| W10/ W35*) | Heating output [kW] | 7,72 | 11,54 | 13,47 | 19,62 | 22,95 | 26,32 |
| Power number [COP] | 5,50 | 5,80 | 5,80 | 5,80 | 5,80 | 5,80 | |
| W10/W55*) | Heating output [kW] | 6,82 | 10,11 | 11,75 | 17,25 | 20,29 | 23,31 |
| Power number [COP] | 3,20 | 3,10 | 3,30 | 3,30 | 3,40 | 3,40 |
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.
A precise calculation will be conducted by a NEURA employee, and will fit your requirements exactly. A rule of thumb says: approx. 180 to 220 litres per hour.
A suction well is the well from which the ground water for the thermal heat pump is taken (or 'sucked').
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.
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.
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.
