The hot water was left running over night about 6 hours in my bathroom sink Would that have caused any damage to the hot water heater

  • What type of gas water heater? A tanked heater I would not expect any problemswith but a tankless depending on the style may have problems of the burner was set to max temp.

No significant damage, just a bit more wear and wasted fuel.

    Mostly the damage will be to your wallet when the next utility bill comes in.

  • I wonder what costs more, the water or the gas/electricity.

  • Depends on how you're heating the water and what current local prices are for water and energy.

  • Based on the water rate (not really - average water bill for families of 4 using X gallons per person-per day, they seem a bit shy of telling the actual rates) in what's claimed to be the highest water rate city (Santa Fe) in this page, circleofblue.org/waternews/2010/world/… I'm going to guess the gas/oil/electricity for heating it by a landslide.

  • America does keep water prices very low. Though our ability to do so is being stretched. (Low enough that it's not unreasonable to use a pump powered by water pressure as a backup for a sump pump. That has the advantage of (mostly) making maintaining power to the pump someone else's problem; even if electric lines are out, water generally has its own massive backups.)
