Perhaps most people have the thermostat on their water heater set higher than it really needs to be? On the other hand, as a bachelor, I concede that my hot water usage pattern is not the same as an average household with a family of 3 to 5 people. I typically do use 100% hot water for my showers. The only exception to this is if I run the dishwasher or the washing machine a few hours before taking a shower, which will result in 100% hot water being too hot.
