Transfer plates are needed for dry hydronic radiant heating to mimic mass.

• A. False
• B. True
• C. They are used to improve efficiency
• D. They are used to reduce noise

Answer: (B)

In a dry hydronic radiant system, you don’t have the dense concrete mass that a traditional wet slab provides. Transfer plates are used to compensate for that by acting as a heat-spreading and heat-storage path. Placed in the floor assembly, these metal plates receive heat from the circulating tubes and distribute it over a larger surface area, while the plate’s own mass stores a bit of energy. This combination helps smooth out temperature swings and creates a more uniform heat output, which is why it’s described as mimicking the mass effect of a concrete floor. While they also improve how effectively heat moves into the floor finish, the core idea is creating a mass-like response in a dry system, not just boosting efficiency or reducing noise.
