I have owned about a dozen pellets stoves over the last 7 or 8 years, 4 of which have been Harman's (Advance, P61A, P61, and PC45). I could approach the P series as 5 separate reviews, but I think it is more useful to look at the as a group.
The P series stoves really have more in common than they do have differences. Harman pellet stoves function in some fundamentally different ways than just about any other pellet stove on the market. Hopper Bottom Trailers. I am of the opinion that Harman makes the best pellet stove on the market, and the P series represents the best of Harman pellet stoves. This review will hopefully explain how I arrived at that conclusion. Lets start with what all Harman's have in common- Pellet Pro system The first thing is what they call the Pellet pro system. This and one other thing are what makes a Harman a Harman.
Apr 12, 2010. Any advise on brands that you may own that are a good choice or the Harman P43 would be nice since I would like to make the best informed decision before dropping the $2500 and then finding out. After searching the web for reviews it seemed that the Harman was one of the top end pellet stoves.
This system is about as close as you can get to a bottom feed system, without out being a bottom feed system. The reason you do not see bottom feed systems is because the were prone to hopper fires. The pellet pro system makes a hopper fire almost impossible (or at least very unlikely) because it creates a separation between the pellets in the hopper and the pellets in the auger.
The Harman P68 Pellet Stove is one of the most powerful pellet stoves in Wisconsin. Easy to clean, high efficiency, and precise temperature control. Heat Your Home with Wood Pellets Wood pellets have become a popular form of heat because they are environmentally friendly, extremely clean burning, a. Mar 13, 2017.

To my knowledge no other pellet stove manufacturer does anything like this. Early Harman Pellet Pro model This system is common to all Harman's, in fact the very first series of pellet stove Harmon made was the Pellet Pro series. An other benefit to this system is that the variations in different size pellets does not effect feed performance. Harman's have 'ESP' The second thing that really sets Harman stoves apart is the use of what they call and ESP probe.
Now some of you might hear ESP probe and think it is a device used on ghost hunters, but that is not the case. The ESP (Exhaust Sensing Probe) basically measures the temperature of the exhaust and regulates the feed rate based on the exhaust. By knowing the exhaust temperature you can extrapolate the heat output of the stove. When you turn most stoves to a particular setting you are basically controlling the feed rate, and that rate is a fixed amount of auger rotation over a fixed amount of time. So the same setting on a most stoves can equal rather different different stove heat outputs based variations in pellets, and as you know from this site there can be some real significant variations in pellets. By contrast Harman stove temperature settings 1-7 reflect a paticular exhaust output temperature and will automatically adjust the feed rate to maintain a consistent output at the given setting.
This system works extremely well, and harman has been perfecting it for over a decade now, so it is a very mature system. Stove Temp versus Room Temp The other common feature to all Harman pellet stoves is the room temperature sensor. It is basically the temperature probe for the onboard thermostat. So you can essentially set a room temperature and the stove will keep it there by raising and lowering the fire, and if it does not call for heat over an extended period the stove will shut off, and then relight when heat is called for again (with the exception of the P38+). Here is where I offer a couple criticisms about the Harman system. It is difficult (not impossible) to hook in a programable thermostat to the stove. Iso Driverpack Solution 2015. The second is that running a Harman in room temperature mode is not nearly as efficient as stove temperature mode.
