What is the temperature of the room?
If the water is significantly warmer than the temperature of the room, something must be adding a large amount of heat to the water. If the lights are off, I would think it would take quite a bit to heat the water to 16 degrees above normal room temperature. What do you have that is adding that much heat???
Are you sure your thermometer is functioning properly?
