Thermal performance of radiant heating floors in furnished enclosed spaces

► The experimental study investigates the furniture effects on the thermal performance of a radiant floor heating, for various furniture types and different external walls insulation. ► The furniture presence in closed spaces induces a reduction of the floor performance in heat transfer, of air temperature and mean radiant temperature. ► With a 40% covered floor ratio and well insulated walls, the reduction of the specific heat flux from floor can reach about 30% with respect to the empty room condition. ► In the same conditions, the air temperature and the mean radiant temperature can decrease of several centigrade degrees.
