Romano Denneboom put the home side in front after just six minutes, and Heerenveen took their one-goal lead into the half-time break.
They wrapped up the three points with five minutes remaining as striker Georgios Samaras scored a second.
Rotterdam club Excelsior have gone into 13th place in the Dutch league table with a superb 2-1 win at Vitesse Arnhem.
It was the home side, however, that took the lead as Gert Claessens made it 1-0 for Vitesse mid-way through the first half.
But Excelsior equalised ten minutes later as Brian Pinas struck back for the visitors.
The Rotterdam club then clinched victory four minutes before half-time as Said Boutahar scored what proved to be the winner at the Gelredome.
The win takes Excelsior two points above Vitesse in the table.
The match between AZ Alkmaar and NAC Breda was postponed due to a frozen pitch.
