you are probably on the verge of a flamewar (haha) but as someone who has owned both, I would like to give you my experience with them....
everything dhall28 has said I pretty much agree with. Harman burns everything and anything I put in there. Period. It burns it cleanly too.
The stove has several features which far and away exceed anything on the Englander. The simple fact that the stove will light and extinguish itself based on a temperature you set it a significant pellet saving feature.
Daily maintenance is an absolute breeze, so is monthly (one ton) maintenance. It REALLY could not be easier.
Now the Englander (at least the two I had).
Yes, the service is great...once you get to talk to someone. I am aware that people who work for this company are active contributors to this forum and that is fantastic. I have spoken with one of them and he has troubleshot my englander stove...he was great at it. But here is the issue. During the heating season they are SLAMMED. Part of the reason is staffing, the other part of the reason is that these things are always broken. When you buy a Harman, chances are you are purchasing through a local dealer and your warranty will cover in home service. Even when the warranty is over, you always have the choice of having someone knowledgeable with your stove to come and fix it. With englander, you just dont get that.
The overall construction of the englander stoves is troublesome as well. The way you access the heat exchanger does not lend itself to easy (or at all) cleaning. This leads to extreme air flow issues. Air flow issues lead to dirty burns. Dirty burns means little heat and cold nights. No amount of attention or work can really overcome this design flaw. With the englander I was doing the equivalent of a harman monthly cleaning EVERY SINGLE DAY. Even then the stove would be burning dirty within 24 hours. This wasnt just a single stove either, this problem was across both of my englander stoves.
In the end, did the englanders save me money over oil? sure. but they also caused 2 chimney fires, constant aggravation, blew through bags of pellets, an ash pan fire (which almost killed my pregnant wife one morning at 3am) etc etc. Switching to pellets with the englander was just way too much work/effort for the return they gave me. When I would show people the stove and answer their questions truthfully, not too many people were enthused at the work required to save money on oil. When I show them my harman, they ask for the dealers number.
Bottom line. I have owned three pellet stoves in 4 years. If I had owned the Harman first, I would still be on number 1. That is over 4k worth of pellet stoves that I have simply replaced.
If you cant buy the harman this year, save your money until you can. You may have an ok experience in the end with the englander, but I promise you, your experience will be an absolute dream with harman.
