Question about Terminator Aquastar 125FX Tankless Water Heater: FX Hood Horizontal Vent
My aquastar is approx 6 years old. The water temperature has gradually decreased over time with the same inlet temperature. The unit lights correctly. It is a natural gas unit. I have never performed any maintenance. Any ideas?
Rebuild the watervalve or replace it. 6 year old unit means its probably one of the 125 series. Probably a polymer gray water valve. Pay attention to the venturi, most likely its very dirty. You can get instructions off the www.boschhotwater.com websight to rebuild this.
