Most cold-weather and many modern NFL stadiums use some form of subsurface field heating , especially where there is natural grass and frequent freezing conditions.

What “heated fields” means

  • Coils or piping systems under the turf circulate heated fluid (often water mixed with glycol) to keep the soil and playing surface above freezing.
  • The goal is not to make the field feel warm like indoors, but to prevent ice buildup, keep the surface from becoming rock‑hard, and help grass survive winter.

Examples of stadiums with heating

Public reporting and industry writeups consistently mention field‑heating systems at several NFL venues, especially in colder markets.

Commonly cited examples include:

  • Lambeau Field (Green Bay Packers) – one of the earliest and most famous heated fields, using miles of hydronic tubing under the surface.
  • Acrisure Stadium (Pittsburgh Steelers) – specifically noted as having a field‑heating system for winter games.
  • Empower Field at Mile High (Denver Broncos) – listed among stadiums with installed heating systems under the turf.
  • M&T Bank Stadium (Baltimore Ravens) – identified in lists of NFL venues using heated fields in cold‑weather cities.
  • Lincoln Financial Field (Philadelphia Eagles) – uses field heating and has been reported to warm the surface into the 50–60°F range for certain games.
  • Arrowhead Stadium (Kansas City Chiefs) – referenced along with other cold‑weather natural‑turf fields that use heating systems.
  • FirstEnergy Stadium/Cleveland Browns Stadium (Cleveland Browns) – discussed in fan and media notes as having a heated field that melts packed snow where players step.

Some dome or retractable‑roof stadiums with natural grass or hybrid systems are also reported to employ heating beneath or around the tray systems to keep the profile within an acceptable temperature range.

Important caveats

  • There is no single, official, always‑up‑to‑date public “master list,” and stadium systems can be upgraded or changed over time.
  • Many synthetic‑turf stadiums in milder climates rely more on snow removal and surface management than on full hydronic heating, so “heated field” is mostly discussed in the context of cold‑weather grass fields.
