Chasing the Stars' 6-162, the Heat cruised to victory with 11 balls to spare on Wednesday as 'keeper Jimmy Peirson (72no) batted for the entire innings to post his highest BBL score.
Peirson combined for an unbeaten 78-run stand with Max Bryant (36no) to deflate the Stars, who were pegged back by Australian white-ball quick Xavier Bartlett (3-25).
"A perfect way to start the tournament," Bartlett said.
"Only being a 10-game tournament, it's really nice to hit the ground running, picking up where we left off last year."
The Stars looked uninspired in the field, creating few chances, with Brisbane appearing in charge of the chase from the outset.
It leaves the Stars, perennial under-achievers, winless after their first two games following a defeat to the Perth Scorchers on Sunday night.
"You want to start the tournament off as as well as you can, and unfortunately, we've had two tough games," Stars allrounder Beau Webster said.
"We still take a lot of positives out of the game, a little bit sloppy in others and hopefully we can tidy them up."
Missing English recruit Tom Alsop (quad), star import Colin Munro (hamstring), as well as star quicks Spencer Johnson (toe) and Michael Neser (hamstring), the Heat handed debuts to Daniel Drew and Tom Whitney.
Jack Wood, who played the last of his two previous BBL games in 2022, opened with Peirson, compiling an important 27.

In his 100th game for the Stars, captain Marcus Stoinis took down Paul Walter for 16 runs in one over, but the veteran allrounder picked out Wood to be dismissed for 26 during the first ball of the power surge.
Veteran Hilton Cartwright made 15 for the Stars, just three days after he was taken off Optus Stadium on a medi-cab and placed in a neck brace following an awkward dive in the field.
Cartwright was released from hospital after being cleared of a serious neck injury following the incident.
In better news for the Stars, veteran Glenn Maxwell has declared himself a certain starter for Friday night's clash with the Strikers at the Adelaide Oval.
Maxwell injured his hamstring playing in a T20 for Australia in November in a major blow for his ambitions of being picked for next year's Test tour of Sri Lanka.
But the 36-year-old had a bowl on the MCG before the Stars played the Heat, later saying he would be fit to return against Adelaide.
The Heat will be next in action on Sunday when they host the Strikers at the Gabba.
