At 120 degrees Fahrenheit / 48 degrees Celsius, the recommended temperature setting for home water heaters, skin requires five minutes of exposure for a full thickness burn to occur. When the temperature of a hot liquid is increased to 140 F / 60 C. it takes only five seconds or less for a serious burn to occur 1.t 120 degrees Fahrenheit / 48 degrees Celsius, the recommended temperature setting for home water heaters, skin requires five minutes of exposure for a full thickness burn to occur.

Every water heater is preset in America to 120F by the manufactures, but some states like Wisconsin require the water heater temp to be at least 125F. I set mine at 125F, which is the recommended setting for my REEM water heater.ome pediatricians instead suggest setting the hot water temperature at 120Â° F (48.88Â° C). With this water temperature, a child would have to run water over the same place for ten minutes prior to receiving a severe burn.
