How do snowmelt systems operate using hydronic principles?

Snowmelt systems operate on the principle of hydronics by circulating warm water beneath the pavement. This method effectively transfers heat to the surface, allowing the snow and ice to melt. The warm water, usually heated by a boiler or other heating sources, flows through a network of pipes embedded in the pavement. As the warm water circulates, it raises the temperature of the concrete or asphalt surface above freezing, which prevents the accumulation of snow and ice.

This technique is particularly efficient because it uses the inherent thermal properties of water, providing consistent heating over a large area. The hydronic principle here hinges on heat transfer: as the warm water moves through the pipes, it radiates heat to the surrounding material, which then warms the ground surface. This creates a clear pathway for vehicles and pedestrians during winter conditions, enhancing safety and accessibility without the need for physical snow removal.
