How many of you haven't been able to take a WARM shower or bath in the past two days? I tried to take one last night (I think the temp was around 9 degrees) and got half a tub of tepid water. . . .So, what's the way to warm up the hot water with such frigid outside temps? Should I wrap a towel around the water heater pipes (one of our water heaters is located outside the house in a closet.) I know we seldom experience this level of cold but it sure would be great to have a nice, hot shower or bath regardless!
