I have to launder a bunch of really dirty stuff. Is there any reason I shouldn't crank the temperature on my hot water heater all the way up? Half of me thinks that's completely nuts and something would surely explode, but the other half of me thinks it must be fine or they wouldn't put those settings on the hot water heater. I've got a 60 gallon natural gas tank that is only a few months old. I figure it would just take a few hours to heat up and then I could put it back. What do you think?
