Die Sanierung eines Altbaus mit einer Wärmepumpe erfordert eine sorgfältige Planung und Berücksichtigung verschiedener Faktoren. Altbauten weisen oft eine geringere Dämmung auf, was die Effizienz der Wärmepumpe beeinträchtigen kann. Dennoch gibt es moderne Lösungen, die speziell für ältere Gebäude entwickelt wurden und eine effiziente Wärmeversorgung ermöglichen. Im Folgenden werden die wichtigsten Aspekte einer solchen Sanierung erläutert.

Arten von Wärmepumpen für Altbauten

Es gibt verschiedene Arten von Wärmepumpen, die sich für den Einsatz in Altbauten eignen. Die Wahl der richtigen Technologie hängt von den Gegebenheiten des Gebäudes und den individuellen Bedürfnissen ab.

Luft-Wasser-Wärmepumpen: Diese sind besonders einfach zu installieren, da sie die Umgebungsluft als Wärmequelle nutzen. Sie eignen sich gut für moderate Klimazonen.
Sole-Wasser-Wärmepumpen: Diese nutzen die Erdwärme und sind sehr effizient, erfordern jedoch eine aufwendigere Installation mit Erdbohrungen oder Flächenkollektoren.
Wasser-Wasser-Wärmepumpen: Diese beziehen Wärme aus Grundwasser und sind äußerst effizient, benötigen jedoch eine geeignete Wasserquelle in der Nähe.

Preisvergleich verschiedener Wärmepumpen

Die Kosten für eine Wärmepumpe variieren je nach Technologie und Hersteller. Im Folgenden finden Sie eine Übersicht der gängigsten Modelle und ihrer Preise.

Modell	Typ	Preis (USD)	Effizienzklasse
