On January 29, 2015, the Calgary Flames announced that they would be moving their AHL affiliate, the Adirondack Flames, to Stockton as one of five charter members of the AHL's new Pacific Division. The team held a name-the-team contest[1] and announced the five finalists as the Blaze, Fire, Heat, Inferno and Scorch on February 24, 2015.[2] The winning name was announced by the Calgary Flames on March 11.
In support of the new division's first season, the AHL played an outdoor game hosted by the Heat. The game, called the Golden State Hockey Rush, was the first AHL outdoor game to be held in California at Raley Field in West Sacramento on December 18, 2015. The Heat defeated the Bakersfield Condors 3–2 in front of 9,357 fans.[3]
The 2019–20 AHL season was curtailed by the COVID-19 pandemic while Stockton was in third place in the Pacific Division and no playoffs were held. The Heat's initial five-year lease with the city to use Stockton Arena expired, but a one-season extension was signed in February 2020.[4] The start of the 2020–21 AHL season was then postponed and eventually led to the creation of temporary Canadian Division due to border crossing restrictions amidst the ongoing pandemic. Due to the Heat being separated from its parent team by the border, the team was relocated for the shortened season to Calgary and shared the Flames' home arena, Scotiabank Saddledome and played only against other Canadian-based AHL teams.[5]
On May 23, 2022, the Calgary Flames announced the relocation of the Heat, to Calgary, starting in the 2022-23 season.[6] On June 14, 2022, the Heat played their final game, losing to the Chicago Wolves in game six of the Western Conference Finals of the 2022 Calder Cup playoffs.[7]
