I just don't see why it is so difficult
determining the COP of such a large system. As
far as I can see you have to make a few
measurements to get a very good idea of a thermal
plants performance. 1) temperature of water going
in, 2) temperature or water going out, 3) water
flow rate, 4) the difference in temperature of
the incoming and outgoing water, 5) energy
required to produce the temperature difference,
6) and the energy consumed from the A.C. mains.
The difference between the energy required to
produce the temperature rise and the energy
consumed from the A.C. Mains is the COP. I am not
taking into account any losses, but with
a system this large and a COP of 50 who gives a damn.

This is probably a naive question on my part, so
I apologize for that. But in the interest of
clarity I wonder if the definition of "excess
heat" and "heat balance" is the same for all

As far as I know it is! I have not hear that
Rossi has redefined this. It is the ratio of
output to input power. Suppose 20 kW of
electricity goes in, 1,000 kW comes out. That
would be COP of 50, which is what Rossi claims.
The I.H. people say that less than 20 kW is coming out, because of heat losses.
In any conventional electrical or combustion
heater, the COP is always less than 1, because
there are heat losses. In a heat pump, the COP
can be higher than 1, but that is not actually a
violation of the laws of thermodynamics (as some
people imagine) because the surroundings outside
the building grow colder. The heat is moved, not generated.

It seems from what you said that the technicians
measured heat from the device but apparently
observed no excess heat due to LENR?
No excess heat from anything.

Is the heat balance the continuous heat provided
by the plant regardless of input? External power
or LENR? I.e balance over time?
I am not sure what you mean, but anyway, heat
out always balances heat it. It is just an
electric heater, as far as anyone can tell. (Anyone other than Rossi.)
Was 1MW heat power ever provided from external power alone?
No, that would not be possible. That takes a
huge power supply transformer, such as what you
see behind a shopping mall. A 1 MW transformer
is the size of a pickup truck. This is just an ordinary warehouse facility.
I believe this is an image of a 1 MW transformer:

If so was 1MW thermal heat output from the
plant? Regardless of the energy source?Â
Based on the data I have seen and the overall
size and shape of the machine, there is no way
this thing could be putting out 1 MW.
