Final answer:
Underfloor duct distribution systems are used in heating systems to distribute heated air through a network of ducts installed underneath the floor. These systems provide a more even distribution of heat and can be used with different heating sources.
Step-by-step explanation:
Underfloor duct distribution systems are typically used in heating systems. These systems involve the use of a network of ducts installed underneath the floor to distribute heated air throughout a building or home. The heated air is supplied through vents or grilles in the floor, allowing for efficient and effective heating of the space.
One advantage of underfloor duct distribution systems is that they provide a more even distribution of heated air compared to traditional forced-air systems. This is because the heated air rises naturally and spreads out across the floor, eliminating cold spots and providing consistent warmth throughout the space.
Additionally, underfloor duct distribution systems can be used with various heating sources, such as gas furnaces or heat pumps. This versatility allows for flexibility in choosing the most suitable heating system for a particular building or home.
