Why would anybody ever install a heat pump system?

Another friend of mine's heat pump just bit the dust
here at -20C. Going to take weeks to get a part for it.
Pretty expensive portable electric heating going on in
that house right now.

That makes 9 heat pumps that will be removed of my
aquaintenances in the last few years now.


Air source getting yanked out of Southern Ontario?

What is the time constant as that 60K heat pump warms
up? Would it ever
reach steady state and a COP of 3? Well maybe when it
was running after
the setback period ended.

60,000 steady state heat output, 20,000 load each
hour hmm, wonder how
many times that will cycle on and off drawing LRA?
Well if a dog year
is 7 years, a Nick year must be 3 years.

Maybe assume it takes 15 minutes to stabalize and
work backwards from
there for your time constant.
