That is the question. There is definitely a point of diminishing returns.
When you say you lowered to water temperature, was that on the boiler, or on
the water heater?

Thanks I already lowered it to 120, the prior owner had it at 160 and
the water was scalding but did come out hot much quicker. Now I have
to run the water for about a minute to get it hot. Makes me wonder if
the energy savings gets offset by the wasted water usage.
