It would be noisy and it would cause wear and tear.
At COP=6 I think you DO have to worry. COP=20, no.
I am sure the COP can be set anywhere you like. It is just a matter of
engineering. The Hyperion brochure on p. 18 shows it varying from 25 to
55 for the small unit (11 kW out, 200 W in), and up to 145 for the
larger unit.
It is not an issue. It never has been. Since 1990 I think it has been
clear that cold fusion can have any ratio you like, once you learn how
to control it. Swartz talked about optimizing output and so did some
others but most researchers I know have said "once we learn to control
it, we can make the ratio will be as high as you like, or infinite (with
zero input)." I think Rossi's results show they were right.
I assume that a unit used for space heating only would have something
like a thermoelectric device and a storage battery to keep itself going,
or to wake itself up. So there would be no waste of external AC power.
Perhaps early models will depend upon AC power. Soon there will be no
such thing as AC, and no power company.
