Every morning I make coffee with a French Press and agonize over what is the cheapest way to boil about three cups of water.
Run the hot water tap for 40 seconds until the water IS hot, and put it in the kettle where a small abount of gas is used to bring it to a boil.
Run the same amount of water “Pipe-temperature” into the kettle which is basically cool, and wait longer for the water to reaching a boiling point.
> Option A) wastes water, Option B) wastes gas
> I had to burn some gas in the first place to get the water hot in the H2O heater, but that’s FAR efficent at heating water compared to an open flame on my stove top.
I guess you need to know the cost of water and the cost of gas, how much water is wasted at the tap waiting for it to get hot, and how much faster hot water boils over cold water.
Do any generalizations indicate it costs a LOT more one way or the other?
What is cheaper? Wasting gas or water?
