We just bought a new refrigerator. One of the installation tasks was to run a couple of gallons of water through the water dispenser to clean it out. I noticed, and was initially alarmed, that the original builders actually tapped a hot water line to supply water to the fridge, since the water from the dispenser was hot.
After googling around a little, I found that there are differing opinions about this. Some people say tapping the hot water is better because: 1) clear ice cubes, 2) less sediment in water (sediment in hot water heater settles to the bottom, but hot water is pulled from the top of the tank), 3) Most of the water the refrigerator pulls will have cooled in the pipes.
On the other hand, the refrigerator manual says “running hot water to the refrigerator may cause damage”.
Does your house use the hot water tap for the refrigerator? What is your opinion about this issue?
