NDB® PICO

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

The slide-in heat pump NDB® PICO compact is designed as a heat pump module for a hot water tank with a standard flange with a 180 mm external diameter. It is laterally flange-mounted to the tank.

The NDB® PICO heat pump can be mounted on the floor or a wall. Moreover, the DHW cylinder can be sited elsewhere.

 

 

With heat pump NDB® PICO, the energy absorption of the ambient heat takes place using the volumes of soil available. The heat pump uses this energy both for cost-effective heating of the room air and for water heating.

 

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
  • Inside Installation
  • Low space requirement

NDB® PICO 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.
2

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.
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

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.
5

Floor heating

The heat taken from the ground is dispersed through the floor to the individual rooms.
6

Wall heating

The warmth taken from the ground may also be easily utilised through wall heating.
7

TRS Room adjustment unit

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

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.

How does this make your life more comfortable:

  • Constant temperature of heat source all year round
  • Lowest space requirement for obtaining heat
  • Plug & Heat® capable

Reliable energy from inside the Earth

The NDB PICO 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

Technical data

NDB PICO 04 230V
B0/ W35*) Heating output [kW] 3,80
Coefficient of performance [COP] 4,00
B0/W55*) Heating output [kW] 3,30
Coefficient of performance[COP] 2,50

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® PICO 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

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.
