Turning off the lights when you aren’t in the room is usually a no-brainer for most people because most people were raised being told that their parent’s didn’t own the electric company. Naturally, the question of whether to turn off the water heater to save additional money on the energy bill comes up. Does it make the same difference as turning off the lights or is the difference it makes miniscule? Overall, studies show that turning off the water heater saves you a few bucks each month because as most water heaters are tank-style, about ten percent of the heat escapes while the water is waiting for you to use it. Therefore, by turning off your water heater you can save ten percent on your energy bill. That’s about two dollars in savings every month on heat loss for heating your water. If your water heater has an on/off disconnect switch , it’s recommended that you consider turning on the water heater a half hour before you need it, giving the tank time to heat your water. Then, you should shut it off again just before you start using hot water. Waiting until after a shower, for example, to turn off your water heater, will start heating the new water that fills the tank, which means you avoid the heat loss situation altogether but still get another full tank of hot water. Sounds like a win-win to me.
Another option for turning off the water heater is by installing a timer that turns off your water heater when you don’t need it or at night. Other ways of lowering your energy bill are :
- By setting your water heater to a set temperature of one hundred twenty degrees Fahrenheit to save an average of three to five percent on your overall energy bill.
- Install water heater traps on your water heater tank. These could save you an average of about $15-30 per month on your bill.
- Consider taking short showers instead of long ones.
- Reduce your time in the shower
- Don’t let the water run… (You can save on your water bill, too).
- For most laundry loads, use cold water.
But in fact, you really don’t need to be heating your water all the time. Your immersion heater will heat up hot water which is stored in a tank. As long as the tank has a good insulator, it will keep the water hot all day, without needing to be constantly reheated. Modern washing machines, dishwashers and electric showers utilize cold water and self-heat so you don’t need a supply of hot water waiting for them in the tank. So go ahead and turn that water heater off when you don’t need it on, you’ll be glad you did. Not only will you save heat but you’ll also save money. After all, every little bit does help at the end of the day even if that bit is only ten percent.
