PEX tubing creates a wide-range of options for hydronic heating. When installed outdoors, you can use PEX to melt snow and ice. Some snow melt systems keep critical areas, (hospital entrances, etc.) clear, while others just save homeowners the effort of shoveling a driveway or walkway.
Snow melt systems need propylene glycol for freeze defense and proper drainage for melted water. Tubing should be spaced 12” apart at the absolute maximum. Thick insulation below the slab facilitates upward heat transfer. Automatic controls and sensors can initiate the system as required, but simple manual controls may also be used.
