What is a common cause of heat duct problems in slab installations?

Improper design and calculations are a prevalent cause of heat duct problems in slab installations. When heating systems are designed, careful consideration must be given to the layout, the size of the ducts, and their capacity to deliver adequate airflow. If these factors are not appropriately calculated, it can lead to inefficiencies, such as inadequate heating or uneven temperature distribution throughout the space.

In slab installations, where the ductwork is often embedded in or runs underneath concrete, any miscalculations can exacerbate the issue. For instance, if the ducts are too small for the airflow required or if they are not optimally positioned, it reduces their effectiveness, leading to hot spots or cold spots within the building. Additionally, if the installation does not account for the thermal mass of the slab, it can lead to further complications, such as heat retention or loss. Correct design and calculations are essential to ensure the ductwork functions effectively within the constraints of a slab setup.
