So then I got the electric kettle out.
1.416kwh so measure for 3:56
1 liter
17.2C
t=1 - 39
t=2 - 55
t=3 - 82 - eff from here
t=3:56 - 89
Rise = 64.8, 4.175 x 64.8 x 1000 = 270734j
5097600j/h -> 254880j

And I did it all because I intended to argue that electric heat, being the inverse of efficiency, could not achieve 100%.

It looks like you proved that when you used it, electricity was 5% efficient.

You may have achieved a new low in energy efficiency!

So what will your next experiment be?

Even worse than the electic use being 5% efficient, it showed that the water absorbed more heat than I put in. Sense I did not test it in my neighbours hot tub I assume that I just didn't mix the water thoroughly when taking the temp readings.

I think my next experiment will be on something even more generally accepted, like the shape of the earth...

Hehehe.. There are no Free Lunches.. However, inverter heat pumps are semi-free..

In that case, I think you have invented a hyper-efficient heat sink.

Wow! A black hole right there in your own home!
