I am not sure what you mean by this. I am not an electrician, but I do play one on TV. I have done all this stuff by the seat of my pants and watching you tube. As far as I know, my water heater is 220. It is also hardwired. There are no outlets in my whole garage (where the water heater lives) except an outlet in the ceiling for the opener.

I performed an interesting test this weekend. The temps this weekend were practically identical and my electrical rates are the same on the weekends.

Saturday set thermostat to 78 degrees. It ran for a total of 533 minutes.
Sunday set thermostat to 77 degrees. It ran for a total of 663 minutes.

So what did sense tell me about the cost. The new plan I am on is 7.798 cents Per kWh. on the weekends. That is the cheapest that it gets.

The sense allows you to see usage on device specific appliances. According to the app, my usage for AC only was.

Saturday 78 degrees = 35.156 kWh x 7.798 = $2.74 ish for ac only.
Sunday 77 degrees = 38.908 kWh x 7.798 = $3.03 ish for ac only.


So was the extra comfort worth the .29 cents? Well... for me personally, no. In fact I wanted to turn it up but my wife's mother is staying with us and she just turned 81. We have to keep her as comfortable as we can. And we save dollars by doing it pennies at a time. I would never of had this data without the sense. One thing my power company does NOT do is break the data down by appliance.

I would like to see your comments on my energy companies rate Plans

This three card monty type of pricing is making us all pay more. I miss the old days when you had a meter.. a guy came and read it, and you paid a rate for what you used.

They have a plan comparison tool that is supposed to show you which plan to use for your specific situation. It was a shame and showed customers plans with used the MOST money. You can read a bit about it here if you are in AZ you SHOULD read it.
