Why is it recommended to use cold water in a coffee pot when making coffee?!

Best Answer - Chosen by Voters

Because hot water has been sitting in your hot water tank and deoxygenated. Cold water is fresher

If you put hot water in the tank, the inline heater is much too powerful. It is designed to take a certain amount of time to heat up a load of cold water, but when it encounters hot water it will heat it up in no time and pass the water through to the coffee basket faster than it can filter it…. overflowing basket, water everywhere, and weak coffee.

There will also be a lot of steam and rattling – after discharge the inline heater is still hot, until the cold water cools it off. Then it heats up the cold water until it is hot enough to flash. Imagine, though, what happens when hot water drops onto a hot heater – it flashes immediately and explosively, blowing water and steam out with some violence.
