UP0636-072
Four-inch copper headers feed warm water to Wirsbo hePEX plus tubing on the field to keep the turf root system at 65°F, keeping playing surface soft and stimulating turf growth even in colder temperatures.

Since the field is usually in a mix of sun and shadow, the designer divided the turf-conditioning system into four zones, running the length of the field from goal to goal. Each zone has 42 PEX tubing loops and a sensor, which communicates the varying demands for heat back to a series of control valves. These valves modulate the flow of warm water from the two mechanical room boilers in response.
