Heat transfer of a finned heating convector into a heated room is considered at different input heat transfer fluid temperature levels. It is shown that with decreasing heat transfer fluid temperature, a maximum ratio of heat flux per unit length of the heating convector to its weight (Q/m) is achieved with a larger distance between the fins. It allows saving metal in manufacturing the finned heating convectors, which is widely used in low-temperature heating systems.
