Comparative energy requirements of radiant space heating

An analytical study compared the energy requirements for a total-building (primarily industrial) radiant space-heating system with those for a convection hot-air scheme. Modeling for the extreme conditions of 100% radiant to 100% convection heat input, the analysis indicated a 14/sup 0/F higher mean radiant temperature for 100% radiant heat than for convection heat with the result that the space-air temperature required for equal comfort was reduced by 14/sup 0/F with radiant heating. Furthermore, radiant heat transfer produced higher inside surface temperatures than the convection mode, although in both cases the surface temperatures were lower than the space-air temperature. Increasing the reflectivity of the wall and ceiling surfaces could raise the effective temperature of the space in radiant systems.
