My outdoor sensor averaged around 7F this morning for a few hours.
The local Underground weather station (1/2 mile from here) showed colder..
Today's Extremes
High Temperature 14.8°F 1:10pm
Low Temperature -2.2°F 7:34am
I left the Sanyos set to 20C overnight and they did good all night.
We were up before 6AM and the temp was still dropping.
Lowest temp indoors was 19C, when I was playing with the set point..
I should have left it at 21C overnight and I think it would have worked better.
Maybe we could have avoided re-starts when trying to jump up 1deg C..
I think the average temp since midnight has been about 8F!
As of 13:20, we've used 24.1 kWh.. ($4.10)..
About 1.826 kW every hour since midnight.. 913 watts used by each unit.
This was the coldest night I've seen in years!!
Right now, it's 16F and there is snow piling up out there for me to shovel..
