NDX®

Heat source ground

 

Thanks to the NDX technology® by NEURA it is possible to transfer energy from the ground directly to the heat pump. Thanks to your NEURA heat pump you can smile despite increasing prices of fuel oil, gas and solid fuels.

And that is because you are heating your house economically and in an environmentally friendly way by using free energy from the environment.

Home-made energy, free of charge

Using your plot of land you will become your own energy provider using the NEURA NDX® ground source heat pump. Thanks to the sun, the rain and geothermal energy your garden will always be 'charged' just like an energy storage unit. Even at very low outside temperatures you will enjoy a constantly available heat source.

The perfect combination

Our optimally conducting copper absorbers laid out in the garden are a guarantee of top operational safety. It is in these absorbers, which are connected directly to the NEURA NDX® ground source heat pump, where the working medium circulates. You have no limitations in terms of garden design - everything is possible excluding plants with deep-reaching roots.

Plug&Heat® – Install & heat

The NEURA NDX ground heat pump is filled at the factory with a cooling medium and tested. It only needs to be connected to the heating system at hour side. There is no need for the usual personnel evacuation, filling and soldering work at the site.

Why it makes your life more comfortable:

  • high efficiency, high capacity even during low temperatures
  • requires only a small area for placement (less than in the case of brine-based systems)
  • Plug & Heat: the simplest installation; ready-to-work, tested delivery straight from the factory
  • no limitations on garden design (excluding deep-rooted plants)
  • thanks to Web Dialog you can access your thermal heat pump any time from anywhere in the world

Ground collector

The cooling medium is pumped directly through the collector piping, absorbing the energy of the ground and thus turning into vapour.
2

NDX® ground thermal heat pump

The cooling medium is compressed and thus 'pumped' up to a higher temperature level. The warmth collected in the cooling medium is transferred to the heating system water in the condenser.
3

House connection

The insulated house connectors are the way between the heat pump and the technical room. The hot heating water flows in the pipes.
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 ground is dispersed through the floor to the individual rooms.
7

Wall heating

The warmth taken from the ground may also be easily utilised through wall heating.

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.

"I have moved into this house equipped with NEURA heat pumps (geo-thermal and hot-water) in March 2011. One of the reasons for me to decide to move into this house was the heating system by NEURA and I was a little surprised of how favourable and reliable this plant works.
I currently inhabit on my own the ground-floor of my house with 140 m².  The house was built in 1999 - 2000, the 38 cm bricks and the many windows allow a great deal of heat to pass through, the house additionally heats up in the sunshine due to the windows, due to the regulation of the floor sensors I have very little fluctuation in temperature.
The advantages of this system for me are the low effort and the safe and reliable function, as well – even if no one is home for several days."

"Our house has been built in 2011 and is located in Southern Styria approx. 270 m above sea level. The particular emphasis has been insulation.
 
We live in the house as a pair and heat a living area of approx. 160 m² on two floors.
The NEURA geo-thermal heater went into operation at Christmas the previous year and was running completely satisfactory, even when we had an outside temperature of minus 18° Celsius. It was pleasantly and consistently warm in the entire house. The heater was running error-free and has never caused uncomfortably strong floor heating.

 

I cannot report any useful experiences about the consumption, because on the one hand we have dried out the floor with the floor heating system before we moved in and the house has actually been built and completed in only seven months."

"We are very satisfied with this solution. We have a ground heat pump for a living area of 140 m². Service water is provided by an electric boiler.


Since our house has very good insulation values (23 KW/m²/year), we maintain an average temperature of 22.32°C throughout the year. (Summer cool, winter warm). The heating costs are approx. € 400 p.a.

We have also connected the washing machine and the dishwasher to the hot water. As a result we have 10% less power consumption and faster washing cycles. Total power for household and heat pump 4466 kWh p.a."

"We have found the best system to heat up our house with the NEURA heat pump and a very good system for hot water with the air heat pump. Even in the first winter we were able to spend comfortable months thanks to the floor heating system - without any problems.

 

We have also been enthusiastic about the system in the last couple of years and the heating costs have dropped tremendously compared to before. Furthermore a heat pump has been selected for us able to heat up the attic as well, which still is under construction. The necessary pipes in the attic have already been installed upon construction of the house."

"We have a NEURA heat pump with surface collectors in the ground for the floor heating system (the ground floor, first floor and office space in the basement are heated) and an additional NEURA air heat pump in the basement for heating up service water. The NEURA company employees have been very kind and able and as a result the installation has been quick and uncomplicated.

 

We have moved in in September 2011. The entire plant is already running for more than one year. We are very happy about very low heating costs, maintenance-free operation, independence of fossil fuels and a pleasant indoor temperature throughout the year. We gladly recommend NEURA based on our experiences."

"The requirements for installation a heat pump in our house have not been very promising. Nevertheless I decided after intensive consulting service to shut down the oil heating and to install a heat pump. The radiators remain and the oil heating should only be used in exceptional cases for peak shaving.
 
Résumé after four heating periods:
 
Never had to heat with oil again, peak supply temperatures of 55°C have been achieved. The heat pump was running nearly permanently upon long-lasting low temperatures.
Thanks to the savings in energy costs I know I have made the right decision in switching to another technology.
 
Energy consumption per year:
Average 6500 KWh. Energy costs of approx. 1100 € --> conforms to current savings compared to oil heating of 50 %."
