by the way. I can't thank all of you enough for all the feedback and input. i am just getting very discouraged right now. i had a great burn last night around 9p. noticed i was close to the aquastat kicking off and said to myself"i sure hope those embers re-light when we demand heat again". well got my answer at 3am

oh! draft damper door set at 2nd notch

Hey wooded, coal seems go require more air than wood....  If you mix with wood it seems to help the re-igniting process...  Also setting your diff closer will help that as well....

Now as far as that thermostatic valve set at 175, I'd try to turn it down about 15 degrees to give u at least some wiggle room

[woodedacres]

if i set it any lower than i am it will not open the valve on the inside boiler. house just will not warm up. i have the thermostat in the house at 70 and my owb just went down to 145. blower on the furnace runs continously. so far this thing is a real POS. if open the draft it will burn nice and hot but get about 3 hours burn time. totally unacceptable..

[Scott7m]

Only 3-4 hours even with coal?

It's really not even cold compared to normal for this time of year, I agree thats unacceptable.

okay. as of 2pm today. neighbor down the road brought down some seasoned wood mostly maple. so dry it is actually cracking. loaded up the stove sprinkled a little anthracite in. just checked the stove 10 minutes ago owb is at 145° down from 150° when i started. open the door roaring fire. damper at 2nd notch. my house boiler down to 125°. i will be on propane in a few hours. only 31° outside. i am so confused as to why i cannot produce heat. best luck i had today was straight anthracite. got up to 165° but not for long...smh

okay what roll does chimney length play? only thing i haven't messed with

gonna give it a couple hours and see what is up. hopefully the temperature. well been up since 3am nursing this turd. gonna try and rest a bit.

Chimney length has absolutely nothing to do with it...  It has a fan that supplies the air so getting draw from a chimney means nothing...  A long chimney can create problems though, I've seen folks with 15 foot chimneys have overheating problems because it can exaggerate a very small air leak. 

However, if you can't get your temp up to 180 or boiling for that matter, using coal in 30 degree weather, then it's useless.......

If your fan is on and you open the door do you see a roaring fire or lazy ?? 

[woodedacres]

first opened it is cozy burn then after say 15sec. it begins to flare up. owb finally generating heat. came up to 165°

Sounds like you need more air, can you open the blower damper a little more? Also what size blower do you have?

I think Scott was talking about turning down the temp on the valve on the inside boiler.

Wood acres... Can I ask if you have applied skirting around your unit?  We are still scratching heads with very similar issues on my 175.   Does anyone know what kind of efficiency losses can be attributed to leaving the owb open underneath?   

[woodedacres]

okay it is now 10 till 6. my wood is half gone however the boiler is up to 175°. at this rate gonna be loading every 6 to 8 hours. mixture of split aged hardwood and anthracite. draft on notch two. gotta a 2500 sq ft home with a boiler rated for 5000+ sq. ft.  i thought i was overkill enough. gonna try cutting the draft back to 1st notch but not till tomorrow. you know i wasn't expecting a miracle when NC told me the burn times but i never expected 25% of what they said it should do. i can't even go to work and have a fire to stoke when i get home. i am sure it will be out after 11 hrs away from it

[woodedacres]

Bull i suppose i could turn the inside boiler down and wouldn't i just burn more wood with more air?

Kart. No skirt

What do you have for insulated pex going into your home?
