The answer to your question is A WHOLE LOT!!!! I went from a average bill of $100 to $50 just by turning off the water heater when not in use. Like Imasaver, I just switch the circuit breaker, it's FREE and easy - why pay $40 - $60 when you can doit for free? The downside, you have to REMEMBER to turn it off and on for when you need it. It's habit to me already and my husband has finally caught on. So we are saving money!!
