Heat source air

The use of the NEURA NDA® air source heat pump does not require digging up your garden, just some space for the installation. The NEURA NDA® air source heat pump may be installed both in the form of a split installation, as well as in the form of a compact hook-up unit in the garden.

You require no technical room. Thanks to the warm gas defrosting function integrated into the heat pump, hassle-free operation is guaranteed down to -23 °C. You can use this reliable source of heat all around the clock, 365 days of the year.

Low space requirement - no earthworks necessary

Thanks to the low space requirement the NEURA NDA air thermal heat pump is especially suitable for small plots of land. The air is present in sufficient quantities, and it is heated again and again by the sun - an endless source of energy for your home!

 

WEBDIALOG®

The NEURA NDA air thermal heat pump is equipped with factory-applied Web Dialog. As a result, you may control or adjust the settings of your heat pump via your laptop or smart phone from anywhere and at any time.

Two variants for installation - a version tailored to fit

The thermal heat pump unit is housed in a noise-insulated synthetic material housing, and includes a fully hermetically sealed compressor unit, condenser, safety devices like the high and low pressure switches, the heating system circulation pump and the entire control unit. It can be installed inside the house in a special technical room. The evaporator is designed to be installed outside and is connected to the thermal heat pump unit using copper piping.


If you have no technical room then you can use the hook-up version. In this situation, the thermal heat pump unit is situated directly beside the evaporator. You receive maximum efficiency using as little space as possible.

Why it makes your life more comfortable:

  • Highest performance coefficient ever measured by the certified AIT inspection unit for any air thermal heat pump (COP = 4,31 for the A2/W35)
  • Lowest ever noise level measured for any thermal heat pump (in silent mode)
  • Installation outside is possible (in the hook-up variant) - no technical room required
  • WEBDIALOG® is included - inspection and control of the thermal heat

1

Evaporator

The air is sucked in by the condenser. The warmth taken from the air is transferred to the cooling medium, which evaporates in effect.
2

Cooling medium piping

This is the connection between the evaporator and the thermal heat pump, through which the cooling medium runs to the heat pump.
3

Thermal heat pump

The cooling medium is compressed, thus 'pumped' to a higher temperature level. The condenser transfers the warmth collected in the cooling medium to the heating system circulation water.
4

TRS Room adjustment unit

The room adjustment unit reports the heat requirements to the heat pump.
5

Heating circuit distribution unit

The individual heating circuits are arranged in such a way so that each room may reach the temperature required by the operator.
6

Floor heating

The heat taken from the air is dispersed through the floor to the individual rooms.

Unnoticeably quiet in Silent Mode

In the silent mode, the performance of the fan integrated into the evaporator is adjusted steplessly between 70% and 100% of its power. Thanks to this, the noise generation is reduced greatly in comparison to other heat pumps.

Because size matters: generously sized evaporator

Thanks to the generously sized evaporator the efficiency of the air thermal heat pump is greatly increased. Furthermore, the generated noise is again reduced.

Why does this make your life more comfortable:

  • Generation of warmth without excessive noise, even at night
  • Efficiency increase through a performance-adjusted DC fan

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.

What is a split variant?

The installation of a thermal heat pump is designated as a split variant when the evaporator is installed outside and the remaining system components are mounted in a related unit inside the house.

What is a Hook-up installation?

The installation of a thermal heat pump is designated as a hook-up variant when the evaporator is installed outside, and the remaining system components (the thermal heat pump unit) are mounted directly beside it. Contrary to the split set-up, the entire system is thus installed outside.

What is the silent mode?

In silent mode the performance of the fan integrated into the evaporator is adjusted steplessly between 70% and 100%. Thanks to this much less noise is generated.

What is defrosting by heated gas?

Because the evaporator can gather ice in the winter, the circulation is simply reversed, and hot cooling medium is pumped into the evaporator. Thanks to this the ice is removed quickly and effectively from the evaporator, always guaranteeing efficient operation.

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.

"I was particularly impressed by the excellent efficiency values of the NEURA heat pump and the relatively high savings made possible by it. The additional utilisation of the considerably smaller heat pump exclusively for service water increases the profitability of the overall plant, as well.

 

The new system has been ideally planned for our already existing house and the renovation and installation works were swift and unproblematic, too. Premium products and top service – I can only recommend it!"

"The NEURA air-to-water heat pump is the most efficient heating system we could find on the market and thereby it is perfect for our new home – also due to the advanced design. The NEURA Premium 2 double evaporator also impresses with its smooth operation (installation location is just off our neighbour’s bedroom)."
