In order to meet the heating needs of rooms of different sizes, radiators come in many size options, with variations in height and length. However, when installing radiators, it is important to consider the load-bearing capacity of the wall, as a radiator filled with water has a certain weight, especially larger radiators that may not be securely mounted on the wall. Generally, radiators longer than 1.4 meters (with a height of 60 centimeters) require additional brackets for support, and radiators taller than 1.8 meters with more than 6 sections also need additional floor supports. If the radiator is of a thicker type, floor supports should be installed based on the actual situation to reduce safety risks due to insufficient load-bearing capacity. Additionally, before installing radiators in a new house, if the wall is made of hollow bricks, it is advisable to chisel the wall and pre-fill it with cement mortar to increase the wall's load-bearing capacity. However, in cases of insufficient load-bearing capacity, installing floor supports is necessary for safety.
