Air-water heat pumps are an exceptionally efficient method of harnessing ambient air for heating or cooling by transferring its energy to water. They operate based on the principle of extracting energy from the external air and channeling it into water, which is then used for space heating or domestic hot water preparation. This allows for effective temperature management even in lower external temperatures. These pumps are environmentally friendly, cost-effective, and durable, making them a popular choice for thermal control.
