If muriatic acid is the choice what would the ratio to water be? I plan on using a pump to circulate the acid through the Heat X, either a SurFlo or a plastic transfer pump.

I have cleaned pumps and exchangers using a solution of 2-3 cups of powdered citric acid in a ~half full 5-gallon bucket of warm water (starting with RO or distilled will help a tad.)  We keep citric acid on hand to remove iron from softeners.
