What does the company Neura do?

The company NEURA AG is a leading manufacturer and retailer of efficient thermal heat pumps, and is based in Austria. Our product range spans thermal heat pumps operating on diverse sources of heat: geothermal, air and water. If hot water is required, we offer efficient hot water heat pumps as part of our product range.

What is the cooling medium (working medium)?

The cooling medium, or the working medium, is the name of the liquid circulating in the thermal heat pump piping. It vaporises even in low temperatures, and is therefore able to store much more thermal energy than water.

How long will I have to wait for my Neura thermal heat pump?

The delivery of a NEURA heat pump is usually within 14 days from the day of the order.

How long does my warranty last?

We manufacture exclusively products of the highest quality. We know what our products can do. That is why we give a 10-year PREMIUM warranty (find our conditions here). One condition for this is the 10-year warranty protocol which needs to be filled in at the installation.

What does direct evaporation mean?

Direct evaporation is used by NEURA in the areas of geothermal heat and air. Direct evaporation means that the cooling medium evaporates directly into the ground collector circuit, here referred to as the evaporator circuit (in the case of the NDX ground thermal heat pumps) or into the evaporator (in the case of the NDA air heat pumps). As a result, no intermediate heat exchanger in required, and the transfer of heat takes place almost without losses.

Where can I find the Neura company?

NEURA has its main quarters in Regau, Upper Austria (OberÖsterreich). Beside other branch offices in Austria, as well as internationally, there is also a range of supply partners available for you in many countries (more on the website).

What makes Neura thermal heat pumps so special?

The thermal heat pumps manufactured by NEURA correspond to the highest quality requirements. They are produced and tested in Austria by the most qualified specialist personnel. A further asset of NEURA heat pumps is their extremely high efficiency. Thanks to our thermal heat pumps your cost recovery time will be greatly reduced. Apart from this, the heat pumps are very quiet during their operation thanks to the noise-insulated housing.

 

We care about service. Our personnel is there for you not just before you decide on a heat pump and not just during the start-up procedure, it is also there for you from then on.

How is it that you can have better heating using a thermal heat pump?

This is possible because heating with a NEURA heat pump respects the environment and as a result it saves money. No CO2 is produced, and the invisible energy of the environment is used. Thanks to a thermal heat pump the energy gathered in the environment is transformed, with the assistance of electricity, into usable heating energy. The relation between heating energy and electricity is approximately 4.5:1 in the case of NEURA thermal heat pumps. Thanks to this, you can save a lot on the heating bills. These savings confirm that the installation of a thermal heat pump pays for itself after a few short years of use, in comparison to heating based on gas, oil, coke or wood chips or even pellet heating.

What is WEBDIALOG®?

WEBDIALOG® allows you to access your NEURA thermal heat pump from anywhere in the world via the Internet or using your smart phone. It will prepare for you statistical reports, calculate heating costs and optimise the operation of the heat pump. You can precisely adjust the operation of the unit and always change any or all of the parameters. Apart from this, the thermal heat pump automatically reports problems or faults to you and the customer service using WEBDIALOG®. In many cases our service personnel is able to restore normal operation of the thermal heat pump remotely.

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.

Do I need an additional heating system beside the heat pump?

An additional heating system is not required. Your NEURA thermal heat pump will heat your house over the entire year reliably even during very low outside temperatures. The thermal heat pump is able to generate flow temperatures of up to 55 °C. Should you require a higher flow temperature then you will additionally need, for example, an electric heating element.

Can a thermal heat pump-based heating system also work with radiators?

The heat pumps of NEURA are fit both for floor heating as well as for radiators.

Can you use the advantages of a thermal heat pump for renovation purposes?

Thermal heat pumps are especially useful in the event of renovations, as they can simply be connected to the old heating system. NEURA offers renovation companies its own hydraulic systems in order to provide optimum operation levels of the heat pumps and maximum possible savings on heating costs.

How quiet is a Neura thermal heat pump?

The NEURA thermal heat pump is one of the quietest thermal heat pumps on the market. Thanks to the noise-insulated and isolated synthetic material housing, the noise generation is reduced to a minimum. This is especially important in the case of the NEURA NDA air thermal heat pump, because the evaporator is placed outside. Thanks to the silent mode of operation the noise generation is greatly reduced.

Where should I locate the Neura thermal heat pump?

For NEURA heat pumps generally two locations are possible: inside the house or outside it. Each thermal heat pump is developed with the option of being installed outside, however this is not always a requirement. The only exceptions are the evaporator of the NDA air thermal heat pump and the NDX direct evaporation heat pump which uses propane (R 290) as a cooling medium, but not the direct evaporation heat pump which uses cooling medium 410 A.

Can I also heat my house water with the thermal heat pump?

Generally you can use your NEURA thermal heat pump to simultaneously heat your water. As, however, the hot water temperature usually is approximately 55 °C (maximum working range of the heat pump), an additional heating system (i. e. an electric heating element) has to be installed. NEURA also offers their own heat pump especially designed to heat your water - the LW640, in three versions. This thermal heat pump reaches temperatures of up to 65 °C.

Do I pay according to the normal electricity tariff for the heat pump?

Thermal heat pumps have their own electricity tariff in Austria. It is more economical than the normal electricity tariff, thus effectively contributing to savings.

What heat sources are available?

In general one can differentiate between three heat sources:

 

  • ground (area collector - direct evaporation, deep drilling - brine)
  • ground water
  • air

 

Which thermal heat pump is right for me?

Our employee will figure out the ideal thermal heat pump for you - one that best matches your needs. Beside your own requirements we also have to consider external conditions. Example: in the case of a ground water heat pump, the ground water should not lie deeper than 15 metres below the surface.

Is the installation of a thermal heat pump heating system supported financially?

The transfer from fossil fuel to ecological energy and the installation of thermal heat pumps is co-financed. The rules are different between the different states of Austria. We will be glad to assist you in the calculation of your individual financial support.

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 collector area do I need?

All NEURA thermal heat pumps are created exactly according to your individual needs. The required collector area is thus calculated by a NEURA employee according to your requirements. In order to provide you with a ballpark figure: The collector area should be more or less double that of the area to be heated.

 

Do I need a technical room for the thermal heat pump?

Thermal heat pumps working on propane (R 290) have to be installed outside. Heat pumps using the medium R 410 A may be installed either inside or outside. You will receive all the necessary advice from a NEURA employee.

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.

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 deep a hole must be drilled for the NDB® thermal heat pump?

This depends on the uptake performance of the soil. This value in turn is derived from the make up of the soil and is usually approximately 50 W/m. Deep drilling is executed down to a maximum depth of 120 metres.

Example: 10 kW thermal heat pump, uptake performance 50 W/m

Total hole length: 200 m = 2 openings, 100 m each

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 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.
