Considering the temperature of only 100C of the ecat output, the value of the thermal energy is not even 1/3 (as you say). It is probably closer to half that, meaning there is little practical gain from this device at all. In fact, you can buy commercial ground-source heat pumps with COP around 5. Of course the capital cost is much higher, but still, until Rossi gets enough output to power the input, it will not represent a revolutionary product.
