We should ask one of them

"What should other man tell if i ask which is the door to heaven?"

Go through the door which he hasn't said

Explanation:
Let two door be A and B
Assume A is the door to heven
Case 1:
Question asked to the lier
The other man always tell the truth so he pick A.But the lier will say B
Case 2:
Question asked to the man who tells truth
The lier will pick B.And the true man tell the truth.

So both will pick B.So go through A the other door
