Warehouse 13 continues to set rating records for Syfy. The show’s sixth episode, “Burnout,” which aired on Aug. 11, was the most watched series telecast in the network’s 17-year history, with a total viewership of 4.4 million.

The previous record for the most-watched series telecast on Syfy had been the fifth episode of Warehouse 13, aired the previous week.

More than 1 million of the 4.4 million total viewership came via DVR playback.

The six episodes of Warehouse 13 broadcast to that date, including full Live + 7 DVR data, all rank in the top 10 most watched series telecasts ever on Syfy.

In head-to-head competition in the 9 p.m. (ET/PT) time slot, Warehouse 13 outperformed TNT’s Hawthorne by +24 percent in Adults 25-54, +11 percent in total viewers, and +9 percent in Adults 18-49.

Warehouse 13 follows two Secret Service agents who find themselves abruptly transferred to a massive, top-secret storage facility in windswept South Dakota that houses every strange artifact, mysterious relic, fantastical object and supernatural souvenir ever collected by the U.S. government. The Warehouse’s caretaker, Artie (Saul Rubinek), charges Pete (Eddie McClintock) and Myka (Joanne Kelly) with chasing down reports of supernatural and paranormal activity in search of new objects to cache at the Warehouse, as well as helping him to control the warehouse itself.

Warehouse 13 airs Tuesdays at 9 p.m. ET/PT, only on Syfy.
