Hot Water Temperature Set Point. If the ambient air temperature is outside of the heat pump's operating
range and heating of water is required, an electric heating unit will heat the water to this setting.
These temperatures are sufficiently hot to cause severe scalding. Water at this temperature may have
been plumbed to fixtures where water hotter than 50°C is allowed, such as the kitchen and laundry.
Refer to:
"How Hot Should the Water Be?"
"Hotter Water Increases the Risk of Scald Injury"
