Harman P68 Pellet Stove Overview

The Harman P68 Pellet Stove is largest and most expensive in Harman’s P series. However, both the Q and R series are more expensive than the P series. It possesses the capability to a heat a home in the range of 1,500 – 3,900 square feet. The stove’s width by height by depth measurements are: 23 ½ ” x 37 ½ ” x 29 ⅜ ”. The P68 comes equipped with a variable speed blower and a 76 pound hopper, as well as having a hopper extension available as an extra feature. The extension is 60 pounds. The P68 also offers decorative touches as extra features, as well as a cast iron hearth pad to protect the floor.

There is a hidden control panel on the side of the stove. This is where the user can set the heat, and Harman claims the stove will maintain the set heat to within 1 degree. This is done using and Exhaust Sensing Probe system. The ESP system constantly monitors heat and adjusts.

A chimney is not required for this stove, as it is direct vent. Harman claims the glass viewing area is cleaner thanks to an air wash system, and the ash pan does not need to be emptied as frequently due to its size.

Harman uses PelletPro ™ technology. This is a system with which the user can burn any grade of pellet fuel at maximum efficiency.

The P68 is priced at $4,219 on the Harman website. This is before any features are added.

Environmental Impact

The Harman P68 Pellet Stove is EPA certified under the 2015 Standards of Performance for New Residential Wood Heaters. EPA looked at a range of stoves, whose pollution (grams/hour) ranged from .5 – 4.5. The P68 checked in at 1.3, rating on the cleaner end.

Troubleshooting and Maintenance

Most of the issues covered in the troubleshooting portion of the manual covers issues with the fire, the hopper, or the fuel. The manual notes if there is a large flame when the stove fires up, it will settle down once the fire is established.

If the stove is not feeding, the manual says it could be due to five things:

  • There is no fuel in the hopper.
  • The sensor for the feeding switch is not operating. This manual advises checking for closed doors, loose or missing gaskets, and the hopper lid.
  • The feed motor is not running. It’s possible not enough fuel or gel was loaded.
  • There is an obstruction in the hopper. The manual advises emptying the hopper and clearing the obstruction.
  • The feed motor has failed.

If fuel is only being partially burned, this could be a result of one or a combination of the following:

  • The feed rate is too high.
  • The air to fuel mixture is off. The manual suggests checking the burn pot and cleaning out the cover and air intake.
  • The burn pot or the heat exchangers may need to be changed.

Harman P68 Pellet Stove Reviews

Very Satisfied

We are in the 11th season using this as our primary heating source. We dump the ash bin every 6 weeks or so and clean with a vacuum only at the end of our 6 month heating season. The igniter stopped working about 4 years ago, but we've not bothered to get it fixed. Eleven seasons!!! Have not had to spend any money on it…till possibly now. It's gotten loud and will need to get it serviced, could be the motor is getting tired. It's been a very efficient stove that has taken very little upkeep!

"Not the claim to fame"

Please don't waste your money. It is not capable of heating a big house, as the guy selling it said, oh sure it will heat it. So over $6000 later, I have a space heater. If you have an open floor plan, it might work, but not an old farmhouse. I had it in the basement at first, did ok, then moved upstairs and heats 3 of the 6 rooms fair, but will not, repeat not, heat the whole house. I could have used the money for baseboard heaters and been better off, so beware before you drop that much money. By the way it is a P68 and 3,400 square foot house. I hope it helps someone out. It is built nice, works good, but I would give it negative 5 star if I could.

"Get yourself a Harman, you won't be disappointed"

I've owned our Harman P68 for 9 years now, and it's really been the best investment I've EVER made. Our house is approximately 4000 square feet and it warms the entire three floors nice and toasty. I can't say that there is anything I don't love about it. Maybe putting the pellets in. I wish a robot could do that for me! ha! We've never had to make a repair or fix on it in the 9 years we've owned it, works like a champ. I can 1000% recommend this unit to anyone that asks me about. I just feel lucky that it was the brand we decided to go with right off the bat. If your ever in the market for a pellet stove, please look at the wide arrange of stoves that Harman has to offer. The stoves are so efficient, beautiful and wonderfully made, you can not choose a better brand.

"Broken and worthless"

Very Unsatisfied

I have owned this particular pellet stove unit for less than a year now. I haven't had it very long. Everyone I know had high praises for this particular brand and model. I liked that it was black, had a modern look about it, and it was so simple to use. I should've realized how cheap it was at that point, but I bought it anyways. I dislike how clogged it becomes even with regular cleanings. I've had to replace the auger 3 times now, all out of pocket expense even though this model came with a warranty. I would not buy this brand or model ever again simply for the fact that it breaks often, and it's as cheap as the suit the salesman was wearing when he sold it to me. The repairs aren't easy to do yourself, the parts are a pain to find let alone order, it constantly breaks down and is flaky like my ex boyfriend. I wouldn't recommend this pellet stove to anyone.

"I LOVE my pellet stove."

I own a Harman P68. I think it is the best investment I ever made. I have owned it for about three years. It replaced a regular wood-burning heater. I have never had to do anything to it, except clean it and keep it full of pellets. It heats an entire house, an old farmhouse, that is really hard to heat, but the Harman does it perfectly and almost effortlessly. I do not have any of the mess or clean up that I had with the wood stove, yet, it IS a wood heat, so I have the feel and the warmth of wood without all the problems. I clean it after I burn a ton of pellets, so there is none of the constant ash problem that you have with wood heat. It feeds itself, has a thermostat–you just set it and walk away. Never had a jammed auger or any other problems, that I hear about from people who bought other brands.I would definitely buy another, as a matter of fact, I will never own anything but a Harman. Would I recommend it to a friend? I recommend it to friends and total strangers all the time. I love the heat, I love the convenience, I love the cleanliness and efficiency, but most of all, I love that it is dependable.
