This paper describes results of a field measurement in which the feasibility of low temperature heating and heating performance improvement by means of convection enhancement around radiators were examined in radiant heating with plastic multi-tubular radiators in an existing reinforced concrete house without thermal insulation. Radiant heating with plastic multi-tubular radiators can make both room air temperatures and MRTs 22〜25℃ and PMVs 0 〜± 0.5 with supply temperature being 30〜36℃. Convection enhancement around radiators by means of small DC fans increases their thermal emissions in 140W/m2 at most.
