Toyota Park Case Study
Toyota Park, the fourth major soccer-specific field in the United States, features a state-of-the-art Uponor turf-conditioning system that keeps the playing surface in excellent condition year-round, no matter the weather or temperature. The system circulates a warm, water-and-glycol mixture through PEX tubing buried underground. The intent is to warm the root zone beneath the grass so the playing surface remains soft and forgiving to falling players, even at sub-freezing temperatures.The radiant heating system consists of roughly 28 miles (nearly 150,000 linear feet) of ¾" Wirsbo hePEX™ tubing, that serpentines from end zone to end zone, eight inches on center and ten inches below the 200-foot by 425-foot playing surface. The only connections are at the copper manifolds, positioned at the south end of the field, where each PEX loop begins and ends -- thus removing potential service issues to outside the playing area. The copper headers are fitted with stub-outs at the factory for making the PEX connections, saving substantial time on the job site.
