Our kitchen sink is about 35 feet of pipe away from the hot water tank. It has one of those single-lever faucets, swing it left for hot, right for cold. Because of that long run, I have to let the water run for roughly 30 seconds before any hot water actually reaches the tap.
So if I just need a quick splash of water and the handle happens to be set toward hot, I’m basically sending heated water down the line that never even makes it to the faucet. It cools in the pipe and the energy’s wasted. If I don’t need hot water, I make a point of turning the lever fully to cold before switching it on.
It might only save a few pennies at a time, but frugal is frugal. #finance
