The "COP factor" is the ratio of output energy to input energy. The problem for e-Cat is that the input energy is electricity, the output is heat, and electricity is much more expensive than heat. They need to get a COP ratio of 10 or more to be economically viable.
In this test a higher COP was sacrificed in order to have a stable reaction and simplify the calculations.
As I said before, it will take some engineering and a better understanding of the theory but the COP will increase.
