Hot Water

So you know how everyone has their own things that just bug them to spend money on. Well, DH is far from frugal in many ways, but for some reason he hates spending money on hot water. We always argue about how high/low to keep the hot water. We have a traditional hot water heater, unfortunately, and I'm not about to invest in an on-demand one, but that would solve the problem.



So, he likes the water just above lukewarm. I keep telling him that it's not sanitary to do the dishes in lukewarm water (I actually don't know if that's true). But plus, I like hot showers, not warm ones. I just feel that every now and then you need hot water.



So I was playing around with the idea of turning the hot water down at night and up during the day, but I don't know if that saves any significant money. Does anyone have any thoughts on that? Does anyone do that?



ETA: I posted too early before doing research, and I learned that

a) DHs setting is actually the recommended one: it's hot enough for most things, it saves money, and prevents scalding, and it also prolongs the life of the heater--less corrosion

b) Most dishwashers have boosters to raise the heat during the wash cycle

c) After thinking about it, lowering and raising the heat every day probably expends more energy than it saves



So.. never mind! DH wins this round. :doh:
