Radiant Floors versus Radiant Walls Using Ceramic Thermal Panels in Mediterranean Dwellings: Annual Energy Demand and Cost-Effective Analysis

The present study focuses on the application of large-format thermal ceramic conditioning panels (TCPs) containing polypropylene (PPR) capillary tube mats in dwellings Mediterranean coast. and energy behaviours were examined once underfloor heating was installed, they compared with an alternative wall application. system implemented a single-family house located Spanish After having monitored during complete one-year cycle, annual demand quantified using Design Builder tool. TCP applied to radiant floors reduced by 5.15% wall-layout alternative. Significant reductions CO2 emissions also achieved, as well 25.19% reduction convection systems. incorporation 24 m2 solar into system, combined cooling systems based lithium chloride, analysed. A 57.46% obtained all-air Finally, amortisation periods investments calculated system. Underfloor proved be more cost-effective than installation. additional cost EUR 21,844 could amortised over approximately 14 years while would 17.4 years.
