Problem
The increasing demand for sustainable heating solutions requires alternatives to traditional fossil fuels, especially in densely populated areas facing heat stress and water management challenges. Existing aquathermy systems can be complex, costly to implement, and require significant manpower for ongoing operation.
Solution
Callic develops and delivers aquathermy systems that harvest ambient heat from open water sources, providing a renewable energy source for heating in residential, commercial, and district heating applications. Their open aquathermy systems utilize advanced installations, sophisticated control technology, and prefabricated equipment to simplify deployment and reduce maintenance. Callic's approach focuses on creating manageable, large-scale aquathermy solutions that integrate sustainable heat generation with improved water management. The company's systems are hydraulically autonomous, allowing for complete assembly and testing in the workshop to minimize on-site work and potential failures.
Target Audience
Callic's primary customers include residential and commercial developers, utility companies, and municipalities seeking sustainable heating solutions for buildings and district heating networks.
