What type of pipe should be used when heating panels are installed in concrete slabs for snow melting?

When selecting a type of pipe for heating panels installed in concrete slabs specifically for snow melting applications, wrought iron pipe is often the most suitable choice due to its durability, strength, and resistance to high temperatures. Wrought iron has excellent thermal conductivity, allowing for efficient heat transfer from the water or fluid circulating within the pipe to the concrete slab.

Additionally, wrought iron can withstand the stress and weight imposed by the concrete and can handle the expansion and contraction that occurs due to temperature fluctuations, which is crucial in snow melting applications. This ensures that the heating system remains effective and reliable over time.

In contrast, PVC and galvanized pipes are not ideal for high-temperature heating applications. PVC has a lower temperature tolerance and could warp or fail under the heat required for effective snow melting. Galvanized pipe, while sturdy, can corrode over time, especially under high temperatures and moisture conditions prevalent in snow melting scenarios. Cast iron, while strong, is typically heavier and may not provide the same level of thermal efficiency as wrought iron in this specific application.
