Paper Title
Experimental Study on Improvement of Heating Efficiency by Removing Internal Scale of Floor Heating System

This paper presents the improvement of heating efficiency after removing internal scale of old heating system (heating pipe, distributor, boiler). The air temperature of chamber was increased maximum 2.4oC, floor surface temperature increased 2.6oC. According to the TRNSYS simulation, the conductivity of system increased 0.088 m/m∙k, about 32.35%. Keywords - Pipe scale, Radiant floor heating, TRNSYS simulation
