<p>A plastic hot-water-circulating radiator having improved heat efficiency and good design. The hot-water-circulating radiator has an exposed heat-radiating section (8) having a hot-water-circulating heat-radiating panel (81)((82)) constructed from pipes made entirely of plastic resin. The heat-radiating panel (81)((82)) has a large number of parallelly arranged vertical plastic pipes (8B) having the same diameter and length. The upper ends and lower ends of the pipes are interconnected by plastic horizontal pipes (8A), and the horizontal pipe (8A) at the lower end is provided with a hot-water supply opening (8S) and a hot-water discharge opening (8R).</p> |
