Just a ballpark. $1? $10? $100? I know rates differ in different areas, but I just want an idea. We'll be filling the non-heated pool soon for the summer, and I'm thinking of running the hose from the laundry tub to put in a tankful of hot water, so we can kick-start the heating process. Last summer with just the solar blanket it was almost 2 weeks until it was warm enough to swim in.

I'm guessing a tankful of water couldn't cost more than $5 or so worth of energy - if we run out of hot water, it takes maybe an hour and a half for the tank to fully heat up. How much gas could that possibly consume? Maybe $5 worth? The cost of the water is irrelevant, because we need the same amount of water to fill the pool. It's just a question of the addition gas cost for hot water.
