Question about Bosch AquaStar Indoor Natural Gas Tankless Water Heater with Vent Hood #125
I've had a Bosch 125 Tankless water for four years or so. Can't remember the exact model, but it has a standing pilot light. It has been working perfectly until this fall. Now all of a sudden the water is not near hot enough. The water just barely gets warm regardless of which faucet is used. Any ideas?
Sounds more like the venturi in the watervalve of the tankless water heater is clogged. I would recommed rebuilding it and paying close attention to properly relubing the pushrod and cleaning the venturi.

Sounds like your mixing valve or tempering valve not unit.Somewhere there is a unit that prevents scalding temperatures- I expect this is your issue find and adjust this first- there are directions on it when you find it.
