Woodstock Progress Hybrid burn times

[Srichards]

Hi all,
Curious what are other PH owners getting for stovetop temps and burn times?
I consider a burn time 200 to 200, although 200 doesn’t do much for my house.
I consider 300 degrees minimum useful, and tend to get about 6 hours of useful heat out of my new PH between reloads.
I’m burning well seasoned maple, white ash, yellow birch. Filling about 75% capacity on hot coals (5-6 splits) and shutting down damper about 95%.
My typical burn times are as follows:
Startup 300,400,500 1 hour
500 2 hours
400 1 hour
300 2 hours
200 3+ hours

Is this typical for PH owners? I can get 12+ hour burn times but 50% if that burn time is 200 stovetop and Isn’t really heating much.
Curious to hear from other PH owners.

I don't own one, but those numbers seem reasonable to me, especially with ash or birch. Hard or soft maple?

Mostly soft maple

Mostly soft maple

If you are working with all soft to med hardwoods there, I think your numbers sound pretty good!

No oak or pine:
My typical burn times are as follows daytime:
Startup 300, 1 hour engage
350 - 400 2 hours
300 1 hour
reload.
Night: 4 - 5 splits. 95% air damper down. I'm sleeping so I don't know what's going on temp wise.
Wake up, 200 and coals.
I never can get to 500. This may be because of a relatively short stack coupled with an outside air intake that for various reasons ended up 6 feet above the floor level when it exits the house.
My temp gauge is on cast in back of left stone.

I see your stove is a hybrid, so i would assume that there is a catalytic combustor in there somewhere. Do you have a gauge that measures the temp, of the cat? Everyone talks about stove top, flue, or cat temperature. Some of the more experienced guys here say stove top is insignificant. I know this doesn't answer your question, but I wondered if you should be reading the temperature at some other point

 

[Rearscreen]

I don't have a cat temp probe. I can tell when it takes off - engage at 300, cut the air supply and if the temp goes up I'm good to go. I look at my temp gauge as a relative reading tool rather than an absolute accurate one.

Is there a question behind your question? Like you don't feel the PH is heating your house well enough?

There are a lot of factors at play here: outside temp, size of your house, quality of insulation and air-sealing, desired indoor temp, placement of stove in your house, etc.

What are the outside temps when you are burning red maple and birch? I only use birch and red maple if the temp is above 20. If it drops below that I have to use oak or locust to get 10 hours. At -10 I have to reload every 6 hours or so.

Last night I loaded at 8:30. 6 pieces of red oak. Outside temp was 34, inside temp was 70. It sat at 350-400 for at least 3 hours. Then I added one more split and went to bed. I got up at 5:00 and the upstairs was 68 (which means downstairs was probably 70-71). Reloaded at 7:30 in the morning. Outside temp was 24, inside house temp was 67, stove top was 280 or so .

I’m going by stovetop temps only because I do not have a cat probe yet. I’m working with WS to see what they recommend

I’d like higher burn times of over 300 degrees. Admittedly I’m not using oak, only red maple, yellow birch, ash.

All I know is when i burn 3-4 old Ash I do not get the long burns like with oak or hedge.I pack the stove as full as I can get it. Again all depends on the size of the splits. Also, If I empty the ash pan alot the coals don't last like if it full of ash because air is getting around those coals from all sides. It took me a whole season to learn how to use this stove and get great heat out put. To me this the best stove I have ever owned and I have had 3 stove before this one.

Despite what are your burn times/temps with oak vs other medium burning wood like old ash/maple

I like to burn mine at 500-550 since my house is pretty big. Im only burning ash and cherry this year so Im getting about 10 on the overnight and I do two 7's a day, low temp when I reload is between 250-300. When I had oak and hickory I was getting 12 hours on the overnight. Have very little this year so saving it for a cold spell.

Must be short stack, I have 26 feet and when its cold I cant keep it below 500.

I’ll definately have to harvest a few oak trees.

If I pack it up say around 830-930 pm by morning when I get up for work 4-445 I have enough coals to get the fire going again.

I get about 8 hours from a hot reload, maybe a logs worth of coals back down to that amount of coals. I'm burning Northwest wood which is probably mostly doug fir. No hardwood. It seems like when I pack it full it just burns hotter, not longer. Any longer than that and the house will still be plenty warm, just not enough coals for a quick relight.

I think I've gotten 10 hours when the coal and log combination was just right. I'm wondering if I have too much draft though. My insulated interior pipe goes straight up 2.5 stories plus another 3ft above the roof. Being able to get consistent 10 hour burns would really be nice because I don't have time to get a fire started on weekday mornings.

Interesting, thanks.
I found some oak and burned that and got about 2 more hours of useful temps, longer burn in the 500 range but overall about a 7 hour burn from 300 back down to 300 stovetop which is when I try to reload.
I always have a lot of coals even when the stovetop is below 200. If almost fully shut down I can probably go 15 hours and still have enough coals to easily reload.

I just don’t get the advertised burn times of 14 hours, there is very little heat coming off the stove with just coals...

How long is your flue? I think I could get 14 if I put in a damper, I planned on doing it this year but was busy and never got around to it. I'm in the northeast so I have access to oaks and hickories, i can get 10 hours with ash and cherry so I think with better wood and a damper 14 might be possible. Theres a poster who said he was getting 14 hours, i think hes in Canada.

I actually had too much draft. I have a 32’ chimney with an insulated double wall steel liner. I have been working with WS they have been awesome. Draft meter showed -15 to -16 which was killing my wood supply. We tried a key damper but didn’t help much and created frequent back puffing.

When you say 10 hours what stovetop temps do you finish with after 10 hours? For me 10 hours is coals and stovetop temp of about 200.

I'm getting sustained higher temps than what you listed above but am also burning seasoned red oak, white oak, and maple. I normally run the stove around 400 degrees and close the air all the way down. I'll go five or more hours before the stove goes below 350 degrees. Also, having a full 12 hour burn time is normal. It also needs to be stated that burn times as well as temp are greatly affected by the amount and type of wood that is being burned. For instance, if I have a shoulder season fire with a few splits of pine, hemlock, or poplar, the stove will quickly warm up into the 300s and then the fire will go out. The burn time is short and the stove does not get as hot. If I have a fire with red oak and locust and the firebox is full, I could have temps above 500 and burn times from 12 to 16 hours.

My cat has slowly been getting clogged from fly ash and I think my burn times have been increasing and heat output decreasing with the air control all the way down. I'm going to let it keep getting clogged until it becomes difficult to sustain a fire with the air control shut down and see how long the burns get. If I like how it burns better, maybe that means a damper will help. I've got a 20'+ interior class A chimney and my draft has always seemed plenty strong.
