This story defies reason. Are we to believe that electricity is the only way the Iraqi's know to heat water? It's like a 120 in the shade over there. Put a pot on the sand next to the mud hut and it will be ready by the time they are done.
We have a Paloma on demand LP fired water heater. We never run out of hot water and we're newlyweds.....Just sayin'......
How about when the power is on, the water gets heated. It doesn't just cool off when the power goes off. It remains warm for a day or so. Adjust the water until it is comfortable. I find that straight water out of the tank without adding the cold works just fine, but of course I gradjeated form High Screwl.
