Radiant heating and cooling represents a significant advancement in HVAC technology, providing superior comfort and efficiency compared to traditional forced-air systems. This method works by circulating heated or cooled water through durable PEX tubing installed within a building's floors, walls, or ceilings. The system heats or cools the surfaces of the room, which then radiate thermal energy evenly and silently, eliminating the drafts, noise, and airborne dust associated with conventional vents and ductwork. PEX tubing is the ideal material for these systems due to its unique combination of properties. Its flexibility allows for easy installation and layout, conforming to any room shape without the need for numerous joints. Its proven durability ensures decades of reliable, leak-free service while embedded within the structure of the building. Furthermore, PEX tubing is available with an oxygen barrier layer, which is critical for protecting the system's metallic components, such as boilers and pumps, from corrosion, thereby ensuring the longevity and efficiency of the entire heating system.
