So,

2.3678 kWh is equal to 8076.539 BTUh. (like heat from a resistive load)

So, if 16,000 BTUh (4.69 kWh) is being pumped..

4.69 / 2.3678 = 1.98 COP??


Humm, 16,000 / 8076.539 = 1.98 !!

The problem is, on a good day you might be getting a lot more output than 16,000 BTU.
And on a bad day, less than 16,000.

But the real problem is being able to measure your BTUh output!

That's one project that I've decided to skip, until I'm in my late 70s (Maybe 80s)
and I'm bored beyond all hope of recovery..
