Hi Louis,

It's a terrific product.  Congratulations.

If I may note one correction.  According to the manufacturer's sales
brochure (and service manual), the lower temperature range for this
heat pump is +5F (-15C), not -4F (-20C) as you had indicated.

This appears to be true of the 24RLQ, its replacement.

If your unit continues to operate down to -8F (-22C), the little guy
is performing exceptionally well, indeed.

My Friedrich (née Fujitsu) is half the size of yours and meets about
80 per cent of my home's total heating requirements, but below -10C it
basically calls it a day.  This latest generation of Fujitsu heat
pumps operate at much colder temperatures and with far greater
efficiency at the lower end of the temperature band.  In the past year
alone, the improvement in performance has been rather remarkable.

Cheers,
Paul

 Hi Nick,

I beg to differ. The OP asked us if an air-source heat pump might help
meet his needs and we're offering our respective opinions.

    Hi Paul
    
    Yes in did, in the sale brochure it's at +5F. But in the
service instruction manual (page 05-20) it do indicate a cutoff at
-4F.
And in practice it's at -8F,  The sales department did had a number,
the maintenance department a other, and the programmer still a other.
Go figure which is good :)
