|
|
3 |
Note temp drop from 7/14pm-7/15am I had not insulated. |
|
|
|
The heat exchanger 7/15, I corrected that and only lost 4 degrees instead of 16 degrees. |

Start temps. are at top of tank before pumps start |
| |
|
6 |
End temps. are for the complete 66 gallon storage tank |
| |
|
7 |
This storage tanks supplies my standard water heater |
| |
|
8 |
Incoming water temp is 55-65 f from the well. |
| |
|
9 |
Average temperature for week was 116 f that is 4 f less than water heater is set |
| |
|
10 |
As you can see from this chart I was able make 95% + of the total hot water needs for the week.
|
| |
|
|
|
| |
|
Savings |
2 pumps 53 watts X 8 hrs X 7 days = 6 KWH |
| |
|
|
...average consumption for hot water = 105 KWH X 95% = 99 KWH for this week savings |
