Literature Review and Case Study on Underfloor Heating Using Heat Pump and Solar Thermal Collector
Keywords:
Underfloor heating system; photovoltaic solar; heat pump and energy efficiency.Abstract
This study explores the design, integration, and performance of underfloor heating systems coupled with heat pumps and solar thermal technologies. A thorough litera-ture review is conducted, covering the historical development of floor heating from ancient civilizations to modern applications using PEX-based hydronic systems. It provided a comprehensive overview of various heat pump classifications—including ground-source (horizontal, vertical, closed-loop, and open-loop) and air-source sys-tems—and their operating principles. This study also examines the role of solar ther-mal collectors in enhancing energy efficiency and reducing reliance on conventional energy sources. A focused analysis of a hybrid system combining photothermal and photovoltaic floor heating, demonstrated the potential for significant energy savings and improved indoor thermal comfort. The findings suggest that such integrated sys-tems offer a sustainable alternative to traditional heating methods, reducing both fossil fuel consumption and environmental pollution. The review highlights key design con-siderations, performance parameters, and the promising applicability of phase change materials (PCMs) for thermal energy storage in modern building heating systems.
