40 gallon electric tank is set to 125, 1 Gallon per minute tankless in kitchen (for sink / dishwasher) is set to at least 135, maybe 140. Just two middle aged, nondisabled adults in our house.
I have mine set at 120 degrees. NO tankless for kitchen. I just run the dishwasher on Sanitize and that takes care of the potential dish problem.
