After almost 1 year of misery with my Pentair Minimax HTR 400 NT TSI NH heater with EO7 error messages Pentair have kindly agreed to change out my unit.

The good news is I have two choices and need your recommendation ASAP please. Either:
1) Pentair with Sta-rite internals or
2) Sta-rite 400

Both are 400 BTU units.

Advice please . . . thanks, John.
