I use a Curb to get real-time energy usage.

The traditional unit showed on average a `45`

minute recovery time at `4500-4900`

watts, since this is less than an hour, I first multiply `4500`

by `.75`

to get `3375`

watts for an hour, finally I divide by `1000`

to get the `3.375`

kWhr.

The new system runs for 3 hours, using an average of `350`

watts, so I first multiply by `3`

which is `1050`

before I divide by `1000`

to get the `1.05`

kWhr.

This is `69%`

decrease in consumption each time the system runs to recover.

The system runs to recover after showers, baths, and dishwasher. 3-6 times per day.
