Precautions for Installing Cast Iron Radiator

When people install cast iron radiators, the requirement is not only to ensure the temperature in the home but also to match the home’s decor without compromising its aesthetics. However, the style of cast iron radiators is unchangeable, making the installation location a crucial focal point.

It is recommended to install cast iron radiators under external windowsills. Ideally, the length of the cast iron radiator should be close to the width of the window. Installing the radiator under the windowsill is aimed at preventing and improving the impact of cold air flow and glass cold radiation descending from the glass window. Generally, cast iron radiators are installed in a visible manner due to higher interior decoration requirements. However, in residential buildings, concealed installation can be adopted. For instance, radiators in nurseries and kindergartens must be concealed or fitted with protective covers.

The assembly of cast iron radiators should not exceed the following values (for coarse column type: 20 sections, fine column type: 25 sections, long wing type: 7 sections). To prevent freezing and cracking of radiators, no radiators should be installed between two exterior doors. However, in stairwells or other areas with a risk of freezing, individual standpipes should be used for heating, and no control valve should be installed in front of the radiator.

If in a vertical single-pipe or double-pipe hot water heating system, two groups of radiators in the same room can be connected in series. Radiators in auxiliary rooms such as kitchens and bathrooms, as well as corridors, can also be connected in series with adjacent rooms. When arranging radiators in stairwells, they should be placed on the lower floor as much as possible. If there are too many cast iron radiators and they cannot be placed on the lower floor, they can be proportionally distributed to the lower floors.
