Harman p43 or enviro min

I have the P43 and absolutely love it! Almost zero maintenance compared to my Englander. I have no experience with the Enviro but my Harman has been fantastic thus far. Best of luck with your decision!

After search for some reviews of the Mini it seems they have done several improvements which leads me to think I don't-won't be a test subject. Resale of the Harman as well as less service and cleaning would lead me to Harman.

Hello
The Mini was the original design. The Mini-A has the upgrades. However both need a large petal impeller blade on the exhaust blower to be a good low drafter . I.E run on heat level 1

See pics of what I did here. > >https://www.hearth.com/talk/threads/...h-can-you-say-titanium-step-drill-bit.129231/

The improvements you speak of are the difference between the mini and the mini-a the switch happened years ago. The biggest issue the stove currently has is the ash pan latch has a plastic(?) bushing, but they are starting to come threw the line with a new "beefier" one and the retrofit is available for free at any Enviro dealer.

Don222 Isn't that what setting up your stove is for, increasing airflow only means compensating by moving the slide damper, and adjusting trim settings

Yes, however I work on many brands of stoves and I can see improvements.

I rebuilt a Mini over the summer, an older one.

I was very dissapointed when even though all the upgrades made a difference, that it was not good enough.

Many other stoves use larger impeller blades and a higher current blower just like what Harman does. The top speed is still 3,000 RPMs but on lower speeds and heat levels the smaller blades that Enviro uses do not cut the mustard!

So on the old Mini, that I rebuilt, I did not install the more expensive wider burn pot or the very expensive new control panel with the combustion trim button. Instead, I installed the ash pan latch and put in the better blower and shazam! It worked super!

can you clarify, I am confused

it has been my experience that if anything the mini draws too much on low and will burn the pellets faster than the feed rate, a proper adjustment fixes this.
what exactly was the issue you were trying to fix with the fan blades?

also the wider burn pot and upgraded control board makes it a different unit, precisely why there was a model number change, the mini and the mini-a are not the same unit.
with out the trim buttons you are not properly setting up the unit thus my confusion, why are the new fan blades necessary?

Hello

Many other brands use the larger blades and do not need all those trim adjustments.

When I rebuilt the Mini, instead of installing a new control panel with the combustion trim button, I put in the bigger blades and bingo, the unit worked great on all heat levels. Amazing!

not trying to be a pain i am genuinely curious what the initial issue was, and can you say for sure if it was the latch or the fan blades that fixed the problem

I have a Mini (new last year) and love it. It is very quiet. Can some one chime in on a P43 and its noise level as compared to a Mini? I will say that having to replacing the combustion motor gasket on a Mini every time you want to give it a thorough clean is a downer. I have been looking at the Harman 52 for the larger portion of the house and like the idea of simply pulling a few screws and cleaning the combustion motor. I do not know if the P43 is that easy.

Thanks for asking, the initial problem was the old Mini (not the Mini-A) unit was not burning very well at all on heat level 1. The burn pot was filling up to much, and unburned pellets were flying out and the flame was lazy.
Most people have to run it on 3 or higher to make it work well.

Adding the latch certainly helped the lazy flame because it stopped room air coming into the ash pan and being pulled up around the burn pot, not thru the burnpot like it should go!

However there still was not enough air on heat level one to stop pellets from overflowing and not burning fully, so the higher current exhaust blower with the large fan blades was the total cure!
I still think added the larger blades to the Mini-A would help that unit too.

Ease of cleaning the p series is as easy as flipping a hold lever and pulling the fan plate. Brush the fan blades and run a brush carefully down the exhaust path care being taken not to damage the ESP. Less than ten minutes for the whole stove. Several posts on youtube.

Not so easy to change the exhaust blower if the set screw is stripped or too frozen.
See my pics. LOL

However if you take the blades off once a year and oil the set screw, then no problem.

Tried remove the fan yesterday to do just that, except use never seize and was a no go. Well maybe if I service the motor properly it will last more than a decade or so.

Thanks everyone for your replies I am now also looking a a piazetta monie, any thoughts?

I would look at who is going to service your stove too!

Only had 1 season with my Harman - loved it! (and you know what last season was like!)
