| How much
money will a water heater timer save? |
| Answer… $15 - $20
or more each month
depending
on how you use hot water and price of electricity.
see pie chart Maybe this is too small for a big investor like you > but consider the return > The savings pays you a tax-free dividend each month forever. > The cost of electricity will go up, so the monthly dividend is guaranteed to grow. > $20 per month x12 months = $240 each year > which, at 14¢ per Kwh, is about 1 free month of electricity each year. > Your water heater appliance will last longer with fewer backflushes and replacements. > The entire DIY-ready project is made with locally-available, off-the-shelf parts that cost $50 -120 (excluding installation). |

Here's the simple math:
My wife and I use a countdown timer to control our water heater > we spend approximately $18.38 per month to heat hot water.
2.)
This means we use: 3500 3.) For an average month: 4.375 Kwh per day x 30 days = 131.2 Kwh per month. 4.) For an average month, we pay: 131.2 Kwh x 14¢ per Kwh = $18.38 Let’s compare $18.38 to the estimated cost printed on the side of our 30 gallon General Electric water heater: 1. The estimated annual cost for our GE water heater is $470-540 per year to operate full time. 2. Assume that GE has given an accurate estimate. 3. Divide $470 by 12 months = $39.16 -or- Divide $540 by 12 months = 45.00 4. If we run our hot water heater full time, it will cost between $39 and $45 per month. |
