Heaney has represented Ulster at all levels and made his senior debut for the Province in a pre-season friendly away to Harlequins in August 2010. He was a member of the Ireland U20 squad that won the 2010 Six Nations Championship and also competed in the IRB Junior World Championships later that year.
Heaney said: "I am delighted to be extending my contract with Ulster. It was a great opportunity to have been given the initial four month contract and I am pleased that I will be able to stay and to continue to represent my Province."
