Is it biblical to burn the heretics?

This article has a list of people burned as heretics by the Church in the past. Is there any Biblical basis for burning the heretics? Which specific verse was used for the judgement on the heretics, which called for the *burning at the stake*? I guess, this verse might have influence on the method of execution, if interpreted wrongly. > “I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do > nothing. If you do not remain in me, you are like a branch that is > thrown away and withers; **such branches are picked up, thrown into the > fire and burned**. (*John 15:5-6*) Couldn't the Church simply ignore the heretics? Is there any command in the Bible to burn the heretics? If such command is there, should we continue to burn the heretics in the Church today?
