My Wife Will Not Wax Should Hot Or Cold Water Go Into A Coffemaker?

Should hot or cold water go into a coffemaker? - my wife will not wax

My wife and I are in total disagreement with them. I have to say that hot water must be put into the pot, because it takes a load of heating elements, and ultimately used to generate electricity to heat cold water will be obtained.

My wife says you must use cold water, hot water not because they cause the components of short-circuit due to shorter period of warming.

My mother-in-law says we are stupid and we should not fight us. She does not care what kind of water goes, where there is a cup of coffee for them.

We use a 10-cup Bunn coffee maker. Of course, we asked to Bunn and not give an answer.

This is a topic which is at stakehigh. If I'm not mistaken, it must comply with washing and waxing the car. If it is correct, then I'll rub your feet with warm oil flavored with strawberry.

So who is right?
