title_body: Will cold water result in cooler coffee with drip coffeemaker?
upvoted_answer: I hardly believe this is directly related to coffee. Still, as a more than 15 year experienced engineer, I would like to answer this question.
  
  The answer is simply and clearly "no".
  
  For the water to be able to travel to the top of the drip coffeemaker machine, it requires to gain some latent heat by changing its state to gas phase first. That's It simply means, it needs to be vaporized first.
  
  Then, just at the top of the coffee and filter, there is a condensation space. At that space the gas (vapor) returns back to liquid phase (water) and starts to drip. Therefore, you obtain a slow flow of heated (to the near evaporation point) dripping water.
  
  I cannot think any other way of bypassing this flow. Even in cheaper drip filter coffee makers.
