How deep should heating coils in a snow melting system be embedded below the concrete surface?

The correct depth for embedding heating coils in a snow melting system is generally around 5 cm (2 in) below the concrete surface. This depth is sufficient to ensure effective heat distribution across the concrete, allowing for efficient melting of snow and ice while also preventing excessive heat loss into the surrounding ground.

A depth of 5 cm provides a balance between efficient heat transfer to the surface and practical installation considerations. If the coils are too close to the surface, they might not create enough warmth to effectively melt the snow, while being too deep could delay the warming effect and lead to wasted energy. Proper spacing and depth are essential to optimize performance and achieve the desired results in snow melting applications.

Other potential options, while they might be seen as slightly more or less robust, do not provide the same effective balance for standard snow melting systems as 5 cm does.
