CoolerAn essential and fundamental component in hot water (or steam) heating systems. Hot water cools down inside radiators (or steam condenses) to provide heat to the room, achieving the purpose of heating. The metal consumption and cost of the radiator occupy a considerable proportion in the heating system, thus, the correct selection of the radiator involves the economic indicators and operating efficiency of the system.

Heaters are divided into radiant heaters and convection heaters according to their heat exchange methods. Convection heaters account for nearly 100% of the heat exchange, sometimes referred to as "convection units"; whereas other heaters exchange heat both by convection and radiation, sometimes called "radiant units."

Radiators are categorized by material, including cast iron radiators, steel radiators, and radiators made from other materials. Other material radiators include those made from aluminum, copper, steel-aluminum composite, copper-aluminum composite, stainless steel-aluminum composite, and enameled materials.

When selecting radiators, the following requirements should be met:

Good thermal properties

(2) Pressure-bearing capacity meets requirements

(3) The appearance should be harmonious with the interior decoration, and its dimensions should accommodate the architectural size and requirements.

(4) Easy to remove dust buildup.
