How hot should I set my water heater in my house to?  Is 250 F good?

No, setting your water heater to 250 F is not a good idea. According to the US Department of Energy, the ideal temperature for a tank-type water heater is 120 F. At this temperature, tap water will maintain a comfortable temperature and be safe for bathing and other everyday uses. You can also set your water heater slightly higher, up to 140 F, for faster hot water delivery. However, setting your water heater too high could result in scalding or scaling and could shorten its lifeskye.
