[Greenbuilding] best PTHP's and mini splits

[Keith Winston]

PTHP? I've heard of ground source and air source, but I have no idea 
what PT stands for (assuming HP stands for Heat Pump).

I believe the Fujitsu RLQ series is far and away the best heat pump on 
the market right now (though I haven't been looking closely in recent 
months, and these things do change!). I've been using them for several 
years. They range from 9-36 kBtu, heat down to 5F without resistance, 
range from 17 to 21 SEER IIRC, and are absolutely whisper silent on the 
indoor unit. The outdoor unit is merely very quiet.
