How is that possible? Premium pellets are about 40 - 45 lb/cubic foot which would mean that a 5 gal bucket would only hold 27 - 30 lbs.
I'm running hard wood pellets that are really putting out the heat and very dense. I get 2 full 5 gallon buckets plus another one 2/3 full for each bag. When I ran Carolina Wood Pellets, I would get 4 buckets. Last year with my Greenways, I got 3 buckets full per bag. They would have to be dense as coal to have 3/4 of a bag in one 5 gallon bucket!

Sorry..... my bucket is 10 liters/2 1/2 gallons..... ;em

Draft test. Draft test. Draft test.

When the stove was installed was the low and high draft set correctly? Too high and your pumping heat out the back.

They can be picked up up for 30 bucks everyone should have one.

Thanks HarmanMan, I'm new to pellet stoves - can you please explain "the low & high draft set correctly" on installation? My dealer told me all I needed to do was do a 2' horizontal vent out the back and plug the unit in.


Also, thanks to everyone with constructive thought,tips and ideas- though I have'nt replied to a lot of posts I've weighed them all and learned a lot so far,

Thank you

I'll let HarmanMan explain but when I installed my P61, Harman frowned on just a horizontal vent. Saying it's their least favored venting method, much prefer some vertical. You are good on the 2 ft part but by the install instructions you will see their preferred methods vs least preferred. And they really don't like a longer horizontal run. I kept mine to 1 ft then went up 25 ft in the end ( fireplace install with 4" vent).

Here is a link to the manual if you dont have it. Look at page 17 and follow the instructions. I have the same venting as you and my draft was so high from the factory i had to turn the control all the way to the lowest setting to get it to where it should be!

I have a feeling you High Draft is going to be a lot higher then the 0.5-0.6 WC that the manual calls for. Mine was over 1.0 when i installed.



This is the cheap air meter i used, works great though.

I check my draft after every full cleaning, lets me know if there are any problems.

Good luck and hope this helps.

HarmanManp43, when using that meter with a pellet stove do you do it with the stove running ? And where do you get access into the vent , is that a drill a hole and plug it when done proposition?

My P43 has a 12mm Bolt on the side of the stove for this purpose XXV i assume has the same. The manual does a better job explaining it then i do but you put it in test mode and then record the high draft. Then after 1 min the stove cylces down wait 15 seconds and record the low draft.

Sorry just re read your post. I havn't done an air velocity test on the venting as all i have is 2ft of vent. This is a static pressure test between the stove and the room air.

Cool, p61 is probably the same, I will look in my manual. Thanks !
 
Harmans have no combustion fan speed control.

Sure they do ...

Sorry to hear about the trouble you're having!

Here's another angle ... The XXV does not provide the same amount of radiant heat that the P-series stoves do and perhaps not the same as your old stove. It could be likely that the XXV is distributing heat throughout your "shed" more evenly than your older stove. Hence the perception that it's not heating as efficiently (as perceived in the room it's in) compared to your old stove. Who knows? I'm with most of the folks ... give it some more time, twiddle with the draft setting, make sure the ESP is not compromised and try to identify any leaks that may exist.

Best of luck!

Good luck there BG, you've caused quite a stir suggesting that stove maker may not be the best thing on this planet... I think every H person online got the notice to come in and tell you it can't be... ha ha. Like most equipment, I'm sure its just a setup issue. Stoves of 20 years ago were good, but stoves of today are better, more complicated too- but better. Be patient, work through it. Don't forget pellet quality, buy the best you can afford.

I went to Amazon to order the meter, I had been looking at them when I had my coal stove but never did buy one. Well it's on Amazon Prime for $17 and change but it says ships in 2-3 months ! I couldn't believe my eyes, I'm used to two days from Amazon items.
 
I'm going to make generic statement of caution here. Unless you really know what you are doing, the average Harman owner shouldn't be messing with the draft adjustment mentioned here unless you happen to have a DDM (Harman's digital diagnostic meter) or access to one. Just sayin'.

Would you mind sharing what you know about Harman's draft adjustment?
When I asked my dealer during my self install, he said that they don't bother with that but yet, Harman
devotes a whole page on this topic.

What I know is this, Harman factory sets that adjustment at a perfect 120 volt power supply and draft. Every install probably drafts a little differently and not all current is 120v on the nose. So in moving that adjustment ya you change the factory setting from their perfect setup. And if you move it, you can always set back to that setting if your move was wrong. Just put a mark where it was set at before you turn the screw.

The manual is very clear as to what the draw should be in a given install. In many cases you may not need to adjust a thing anyway but you will never know that without first taking a meter reading.

My wife just ordered an item from Amazon with the same 2-3 MONTH projection! Once, it happened to me too. I'm not sure why they do that but it certainly is something to watch out for especially if we are Prime 'spoiled'. Maybe they are quoting the next shipment from China?

Amazon covering the basses. I just ordered an item and it had a long wait but was shipped four days later. Still feeling the sting of UPS Xmas orders being very late.

This is a difficult thing to diagnose because you don't have facts to backup your issue. People have tired to give you an answer and it sounds like we are trying to diagnose your perception.

Again, how are you measuring the temp in the house to determine that both stoves are maintaining the same ambient temp?

Speed up your distribution fan to high and go back to room temp. Where is your room temp sensor located?

All we have to go on is his perception that the old stove is more efficient than the new one but he stonewalls when asked for helpful info.

Could be. I didn't order the meter and of course now my imagination is working on me that the draft could off in my setup. It's probably fine but the mechanic in me likes to know that for sure!

Sure...what I know is what I said..."most" people shouldn't be messing with the low draft adjustment unless they know what they are doing. I'm sure there are folks here who are quite comfortable with using a draft meter and checking their low draft setting. To that I say go ahead...Harman sets the voltage right at 120V from the factory and in "most" cases, it won't need adjusting in the field. They devote a page to it in the installation manual not the operation manual. I'll grant you, most of us here that participate regularly are probably pretty pellet stove savvy as it relates to our own individual brand and level of expertise. I just don't want the occasional reader to grab a screwdriver and start messing with something that they shouldn't.

And we've strayed way away from the OPs issue of not turning his fan up high enough!!!
 
I'm now running the fan on M as suggested by the dealer tech. when at #4 or 5.
I turn the fan down just under M when below #4
Best efficiency is when the convection fan is at the highest speed. Set it to the highest speed your ears will tolerate and leave it there.

I'm with ya Harvey, I shitcanned what the dealers tech. told me days ago - but I did give her suggestion(running the fan lower) a try. I forgot to mentioned in the OP that for the first day I ran the fan wide open and the next day is when the dealer tech. told me to run it lower. I've been running the fan on high(or close to it) the last few days. Been doing some experimenting and it's running about as good as it's gonna get.

I just was expecting too much but am still thrilled with the stove. While my old Avalon outdoes(efficiencywise) my new Harman in my drafty shed hopefully the Harman will do better when put in the new future house
