In brief: Related
The heart has to squeeze effectively, but also has to be able to relax inbetween squeezing to allow adequate filling.
If it can't relax that is considered diastolic heart failure. Congestive heart failure can be either systolic (the squeezing action) or diastolic (the relaxing function). Impairment of either one or both can lead to congestive heart failure.

In brief: Stiff heart muscle
Congestive heart failure can be divided into systolic and diastolic types.
Systolic heart failure means the heart doesn't pump well enough because the muscles are weak and squeeze very well. Diastolic heart failure means the muscles of the heart are too stiff. As a result, the heart can't fill with blood very easily which also means it can't function as well as a pump.

In brief: A subclass
CHF can result from systolic heart failure (failure to contract properly), from diastolic heart failure (failure to relax the heart), or from valvular heart disease. Volume overload from renal failure can also cause CHF.

In brief: Different
CHF can be diastolic or systolic or mixed.
Diastolic dysfunction is a problem with dilatation of heart, whereas systolic dysfunction is a problem with contraction of the heart.
