United were in control of proceedings on the scoreboard but it was the Heart who could count themselves unlucky after creating a swag of chances but their inefficiency in front of goal ended up being their downfall.
Gold Coast defender Bas van den Brink kicked off happenings with a header from a corner just before half-time and things only got better for the home side prior to the hour-mark when Bruce Djite was brought down in the area by Heart centre-half Michael Beauchamp.
Jason Culina stepped up to the spot and converted to make it 2-0 before Djite set him up for a second in the 77th minute to kill off the luckless Heart who remain fifth on the table as United edge closer to second-placed Adelaide United who lost in Wellington earlier tonight.
