I noticed the same thing as begreen with my Dutchwest. The blower definitely pulls more heat off the stove. I can recover room temp faster, and hold room temp higher in very cold conditions. Your PH may work fine, heating your particular space (I don't know the size or layout,) but the fact remains that it's possible to pull more heat off a stove, and faster, using a blower. The more warm air you produce, the better it will move into more distant areas owing to a stronger convection loop. Of course fans can
also be used to enhance convection loops between rooms. That said, I would probably get the PH and, when needed, use a small fan somewhere close to the stove to pull off more heat. I'm a big fan of Woodstock quality, and I love the soapstone radiation, which is definitely more penetrating (intense?) than I get off a similarly-sized steel stove. And I'm totally hooked (since the Dutchwest) on the clean convenience of a grated ash system...high on the list of must-haves for me.
If the OP ends up with two stoves, having a fan blowing on the PH probably won't be necessary; Just ride the slow, even radiation of the PH in moderate conditions and during the day, and fire up the other stove for a night load, or all day when it's cold out.
@Joyboy, yes, cat stoves in general, and the PH in particular, are noted for sipping wood. I've run a Fireview; Guys that have had it, then got a PH said it seemed they ended up using even
less wood. I think the exhaust routing in the PH makes it extremely efficient at extracting heat. Efficiencies and outputs from EPA testing are listed here:

BTW, are you dealing with any vaulted ceilings? I don't think so, but thought I'd ask...
