Consider Thiessen polygons as an alternative to heat maps
Another nice feature of Thiessen polygons is that they are an exact interpolator. That means that the model produces the exact value at the location of the data point. This is not the case with the majority of interpolators, including kriging.
Lesson: if considering heat maps or interpolation look into Thiessen polygons first. It may be the simplest yet best tool for the job.
