Power saving with the water heater

AI Thread Summary
Turning a water heater on and off can save power, but the effectiveness depends on the duration it remains off. For short periods, like a few hours, the savings are negligible, while longer durations, such as a month, can lead to significant savings. Installing a timer for the water heater can be beneficial, with potential savings covering the cost of the timer over time. Additionally, improving water heater efficiency through better insulation or adjusting the temperature settings can further reduce energy consumption. Some participants suggest exploring renewable energy options like solar or wind power, although concerns about costs and feasibility are noted, particularly in locations like Guam.

Will turning the water heater on and off save pwoer!>!>?!?

How long did you plan to turn it off? If you're just going to turn it off a few hours and turn it back on when it's time to shower, probably not. But if you're going away for a month's vacation, it would.
 
Perhaps instead of being concerned with the consumption aspect you should simply increase amount of electricity available to you - get solar cells, windmills, etc?
 
I notice you are in Guam. If you are considering getting a timer that controls the time your electric heater switches on, I'd say you would save enough money in eight years to pay for the timer.

:smile:

thats cold dude
 
Some water heaters are more efficient, or insulation on the heater (not sure of the details on this one) can help reduce energy consumption, or turning it down a degree or two (or five) so it doesn't need to heat up so much - These things help too.

I'm not planning on anything, I just am curious. The first one.

Solar cells would cost more than I would gain, and windmills! I don't have enough land, I don't have enough money, and Greenpeace people would be knocking on my door how I'm hunting birds unfairly.

Well, I'm not considering the water at all for that reason.
