The system can be divided into 4 zones:

Geothermal probe circuit zone

This zone is essentially composed of:

·       Geothermal probes of the 2-pipe type

·       Distribution manifold for geothermal probes with devices for shut-off and balancing of the individual probes

·       Control, expansion and safety equipment

·       Thermal medium deaerator/dirt separator

The circuit must be filled with water and any necessary additives (antifreeze, protective and anti-algae products) in relation to the specific characteristics of the water used and the requirements of the system.

Water/water heat pump zone

It essentially consists of 1 water/water type combined heat pump, fitted with the following components:

·       Control, expansion and safety equipment

·       High efficiency circulation pump

·       Internal tank for the production and storage of domestic hot water

·       Summer/winter mode selector

·       Charging unit

System zone

This zone essentially consists of:

·       Regulating unit for panels, by-pass type, and primary medium distribution kits for radiators

·       Radiators: radiant panels, radiators,

·       dehumidification array

Winter or summer operating mode is activated using the relevant heat pump selector.

Domestic hot water distribution zone

Domestic hot water production takes place in the relevant storage tank within the heat pump.
The anticipated distribution system does not feature recirculation and is equipped with a thermostatic mixing valve.
Plus, in the case of high water hardness values or if so required by current legislation or by the boiler manufacturer, a specific water treatment system must be installed.
 

Note:
The system must be created in observance of any relevant regulations and specifications.
