Brunnenanlage

Im Prinzip ähnlich wie bei den Erdwärmesonden können die Temperaturen des Untergrundes, in diesem Fall direkt des Grundwassers, über zwei Brunnen (Entnahme- und Schluckbrunnen) über eine Wärmepumpenanlage zum Heizen und Kühlen genutzt werden.

Wesentliche Randbedingungen für die Planungen einer Brunnenanlage sind:

ein ergiebiger Grundwasserleiter
die Grundwasserqualitäten
die Abstände zwischen Pump- und Schluckbrunnen
urbane Nutzungen im Umfeld
notwendige Brunnentiefen sowie
Fragen der Betriebssicherheit
