We did laundry yesterday and took showers after our evening bike ride,
then I went down to log the numbers last night while the A7 was still running (it was almost done)
and saw 61.6 C displayed (at the input Tee). That's
143F ! That R22 can really get up there!

That seems a little high. Should I be worried?
~~~
23 days (or 552 hours) of operation and the A7 has run for almost 38 hours, Using 22.65 kWh.
That's almost 1kWh ($00.1633) per day.
If the temperature in the our basement stayed at 72F all year round,
and we burned 365 kWh per year, that would come to $59.60 per year!!
For oil at $2 a day, it would cost $712 per year (regardless of basement temp).
It's already getting colder..
Here's the outdoor temp chart for the last 28 days.
During cold weather, it's going to take more kWh to get that hot water.
However, our winter hot water requirements normally drop a bit..
Anyways, my wild guess for 1 year is 100 bucks, +/- $20
