Theres a way to clean a coiled heat exchanger with a rotating brush and a water flush, it's used a lot to maintain air conditioning systems in big buildings. Maybe a large HVAC contractor in your area would have something like that.

Yes to Rydlime!

Used it here at work on condenser water barrels. or Chloroben DE, but only licensed plumbers can buy it...90% hydrochloric. Need to pipe up an acid pump, pump solution thru and thru until it clears...this kind of problem will affect most all HX/tankless heater owners sooner or later!
