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.

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:
What is standard for all NEURA hot water heat pumps? They are optimally designed for preparing hot water, work with highest efficiency and provide the heating system with a well-earned summer break.
The warmth from the cellar or rooms used for storage - often also waste heat from appliances like the freezer or washing machine - serves the type L NEURA warm water heat pump as a supplier of energy in the air circulation process. Thanks to direct condensation and modern cam and piston compressor technology, the water temperature may reach up to 65 °C. And in addition, the air in the rooms is heavily dried. This doesn't only help the wet laundry, but also the basement walls, which are often in danger from condensing water.
The warm water heat pump of the R type does not require any storage or cellar rooms. This new technology utilises the residual heat from the heating circulation system. What is a nice additional effect is being able to somewhat counteract the effect of overheating of rooms by sunlight in the summer.
Type L: The air is sucked in by the evaporator. The warmth taken from the air is transferred to the cooling medium, which thus vaporises.
Type R: The circulation is routed through the evaporator, providing energy to the warm water thermal heat pump.
Type E: The cooling medium is vaporised in the ground collector, and then provides the energy to the LW thermal heat pump
The compressor compresses the cooling medium in vapour form, thus 'pumping' it up to a higher temperature level.
In the LW series the buffer collector serves as the condenser. This means that the warm water thermal heat pump releases the energy to the hot water.

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.
Direct condensation means that the buffer storage unit may be seen as a condenser. It performs some of the tasks of a unit taking energy from the hot water thermal heat pump, directly and without any complicated routes.
Monovalent: The thermal heat pump is designed 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.
