He's not an early morning person, but he does stay quite late, until about 7 or 8 in the evening, she said.

What is a BTU. A BTU, short for British Thermal Unit, is a basic measure of thermal (heat) energy. One BTU is the amount of energy needed to heat one pound of water one degree Fahrenheit, measured at its heaviest point. In other words, if you placed 16 ounces of water at 59Â°F into a stovetop pan and turned on the gas burner, it would take one BTU to raise the temperature of the water to 60Â°F.
