Heat pumps are devices that transfer heat from one place to another, providing both heating and cooling solutions for homes and buildings. They work by extracting heat from the air, ground, or water and moving it indoors during winter, while reversing the process in summer to cool spaces. This makes them an energy-efficient alternative to traditional heating systems. By utilizing renewable energy sources, heat pumps can significantly reduce energy consumption and greenhouse gas emissions. They are increasingly popular in residential and commercial applications, contributing to a more sustainable future. Their versatility and efficiency make them a key player in modern HVAC systems.
