Warm-up in the Wintertime

In Western Kentucky in 2009 we had the most horrific ice storm since I was a four year old in the sixties. The power was out from 5 to 19 days, 13 days at my house and my luxury during it all was my hot water heater (it's gas). It warmed up the whole room while I was in the shower even though my thermostat was at fifty-four degrees with only a fireplace and 16 degrees in Fahrenheit outside.
