Unless this situation has existed since it was installed, the heate may need servicing. Heaters do not “explode” from having the temperature increased. They explode due to serious malfunctions that have nothing to do with the temperature setting and can occur even if set to “cool”. But I am curious as to what she means by “explode” when a water heater really explodes their is not usually any house left to install a new water heater into.
