I have heard good things and other things about the Heat Pump, it depends a lot on the Temps. We have one in our stick house and when it gets in the teens, we will turn on the fireplace and it heats much quicker. I'm going Monday and have the second A/C installed and will go with the Penguin 13,500 in the bedroom. Would have went with the 15,000 but I wanted the low profile for the front and it pulls a few less amps. I will add the heat strip myself, its just a plug in and play very easy install, we had the heat strip on the last 5er. It doesn't put out a lot of heat but it will knock the chill down a little so DW can get things going when she first gets up.... When in Montana in July the mornings were cool in the early morning.
