I have a Bosch natural gas tankless water heater and the problem I have is that the burners do not ignite until there is ,8 of a gallon of water flowing through it. Thus, once you have suficent hot water,...
Unfortunately nothing can be done about the minimum flow for activation.
However, your heater should have a flow control dial that you can turn all the way clockwise which will reduce your activation rate to about 0.5 gal. but that's the absolute lowest.
If the reason is to conserve water than that's about all you can do.
However, if its because the water is too hot and your mixing in cold which is increasing the volume of water you are using, then you should have a burner or flame control, if its a dial turn clockwise for less flame on the burner or the heater may have a slide control which sliding more to the left will lower the burner flame.
Don't forget water valve maintenance in your manual, follow instructions for a water valve rebuild to restore performance to the heater.
That's about it.
