Deleting google maps heatmap layer

I am writing a google heatMap application and I need to delete the data which heatmap layer contains. Is there some solution? I went trough all stack overflow and can not find the proper solution. Everywhere they advise to do something like this:

heatmap.setMap(null) but this only hides the map, and when I do heatmap.setMap(map) the layer appears again

You can easily just set the data to an empty array

heatmap.setData([])
heatmap.setMap(this.map)

You can't delete a variable in javascript but you can assign as undefined 

 heatmap = undefined;

so heatmap is not a valid object
