Heat source deep drilling

When the available area for the laying out of a ground collector is not sufficient, the use of a soil thermal probe is a possible option. The probe is introduced into a drilled opening and covered. Brine, a solution protecting against the freezing of water, circulates in the probe, taking up the thermal heat from the ground and running it to the heat pump.

Because the temperature of the ground is constant throughout the entire year, also in winter you will have a secure heat source for your home.

Depending on the properties of the soil, for 1 kW of thermal heating power of the heat pump one needs approx. 15 to 20 m probe depth.

Highest efficiency 365 days per year

A NEURA NDB thermal heat pump may work with a drill hole depth of up to 100 metres. For the option of deep drilling, the primary heat source is not surface heat absorbed from the sun, but the warmth from the interior of the Earth. The temperature is constant throughout the entire year, and guarantees warmth even during very low outside temperatures, hassle-free operation and excellent performance.

Heating or cooling - whatever you wish for

Thanks to the NEURA NDB thermal heat pump you may not only heat. You can also use the heat pump for cooling, in order to achieve a nice interior atmosphere in the summer. The cooling takes place through the 'heating system'. The warmth collected from the rooms is routed through the heat pump to the soil/the deep hole, effecting a regeneration. Thus you more or less 'charge' the soil in order to be able to heat your house in the winter.

Why it makes your life more comfortable:

  • Highest efficiency even during periods of very low outside temperatures
  • Usable over the entire year - for heating and for cooling
  • Can be installed outside or inside
  • Low space requirement

1

Floor heating

The heat taken from the ground is dispersed through the floor to the individual rooms.
2

Wall heating

The warmth taken from the ground may also be easily utilised through wall heating.
3

House connection

The insulation house connection forms the point of connection between the thermal heat pump and the technical room. The heated water flows inside the connections.
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

NDB® thermal heat pumps

The evaporator transfers the heat taken up to the cooling medium, causing it to evaporate. Then the cooling medium is compressed and 'pumped' to a higher temperature level. The transfer of the collected heat to the heating system water from the cooling medium takes place in the condenser.
7

LW 640 hot water thermal heat pump

Thanks to the LW640 you have at your disposal a small compact thermal heat pump for the purpose of warming your usable water. The heat pump is installed directly on the boiler.
8

Brine distribution unit / Depth probe

The brine distribution unit distributes the brine to the individual probes. The brine circulating in the probe takes the warmth from the ground, running it then to the thermal heat pump.

How does this make your life more comfortable:

  • Constant temperature of heat source all year round
  • Lowest space requirement for obtaining heat
  • No technical room necessary thanks to installation outside
  • Plug & Heat® capable

Reliable energy from inside the Earth

The NDB heat pump uses the heat energy from inside the Earth. Already at a depth of 10 metres the temperature of the soil is 7 to 10 °C. Thanks to a temperature increase of 3 °C every 100 m one can guarantee highest efficiency both in transitional seasons as well as in the Winter during periods of very low outside temperatures.

Quiet, vibration-free operation

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.

Why does this make your life more comfortable:

  • Constant temperature of the soil all year round is used optimally
  • No excessive noise thanks to insulated housing

What are the available modes of operation?

Monovalent: The heat pump is planned so that it can cover the entire heating requirements of the house.

 

Bivalent, alternative: The 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 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

Customer comment

"We are very happy with this product after two already “warm” winters we have overcome thanks to the NEURA heat pump. Even the service was – if there had been a problem – accommodation and could be quickly on the scene.
 
It is pleasantly warm at our house, especially now in the transition time where the heater is not yet running. Cold feet are no longer a problem thanks to the floor-heating system.
 
If we wish to have it warmer – this is no problem – just set the room thermostat a few degrees higher
and it doesn’t take long at all until the desired temperature is reached.
 
Since there is no artificial rockwork for the Europe type – which would have suited our house style immensely and we didn’t like the light concrete housing too much, we let our creativity take its course and have crafted our own “housing” (as can be seen on the photo).

 
All things considered we can only praise NEURA and the product and recommend it with clear conscience!
 
We are looking forward to many coming cold winters outside and cosy-warm in the house!"
