I just wanted to share that one month last year we experimented with our electric bill. We discovered that by turning off our hot water heater that we saved at least $40 for the month. (We don't have it off now.) Step 1: Turn off water heater at breaker switch (see note below). Step 2: Heat water in the teakettle on the stove or use your Instant Hot (which is another hot water heater). Step 3: Fill a solar shower bag with 1/2 cold and 1/2 hot or thereabouts to make it shower temperatures. Fill the cold water first. Step 4: Hang the solar shower bag in the shower over a rigid pole with no risk of it falling on someone. Step 5: Enjoy your shower (that was very cheap)!!!! Downsides: Your electric dishwasher won't heat the water hot enough I think so hand washing might be in order. No hot water for washing clothes. You have to plan for showers. The inside of the solar shower bag might get moldy so you have to sanitize it periodically with something, and make sure it airs out each time. Please use extreme caution in handling those electric boxes (breaker switches) as they can throw major shocks if you mess around and handle them I have heard. DON'T flip the switch on and off all the time- very dangerous I have heard. Unexpectedly they can shock and kill my DH says.
