If the draft is strong enough to hold the fire view door closed, you might see the boiler temperature creep up. If the boiler temperature stays stable without the baro you should be fine.

Ok, so since Nov 8th, here is what I have been seeing. Ash pan is about 2/3 full every 2 to 3 days. Last 2 days were the coldest yet at 18deg night 32 day. Ash pan over these 1 day filled a 5 gal bucket. Weighed the ash and it came to 20lbs. Ash looks like 15% so 20/.15=133.3lbs per day. House set at 71deg, with coal also supplying part of dhw. Last year on oil I would have used 12 gal for a similar day house set at 68. Comparing usage by BTU's, Oil- 138,690 btu per/gal*12=1,664280btu's, Coal 12,200 btu per/lb*133.3= 1,626,260. I am pretty close, with the coal being more efficient. The big diff is the savings. Coal cost 200.00 a ton, so thats .10 cent per/lb, so $13.33 per day vs 12 gal oil at current to day quote $2.75 per/gal = $33.00. With money saved Now i can begin to tighten up the house some, or have more fun improving the radiator system. Here are some pics of the ASH, and the total ash pile year to date. I put the chair in there for scale, just shy of a full loader bucket. Also the coal gopher pic.

Your ash looks better than mine. I have a little more rocky texture but we have been unseasonably warm in my area. I expect my ash to break down more like yours if it ever gets cold here and the boiler gets to run more.

Nice Gofer!

The Cats will love your ash pile. Just don't let them get in the coal bin. :lol:

With a big wind it pulls about -.05 to .06.
A wind gust is only a few seconds so, no big deal. You can leave the baro out of the equation as long as the draft isn't holding the fire door shut.

You should connect an hour meter, or if you have a mechanical electric clock, connect it to your fan motor. Once you know how long it is running you can figure out if you need to reduce the fan speed to get a more complete burn. It looks like your 260 has the belt drive fan. Changing speed is a simple matter of changing pulleys.

Rob, no the draft has never shut the door,even when we had 40mph gusts last month. Never would have thought of that. Guess its good,so I Will redo stack at shutdown.

Ok, will get a meter,or clock on it. Based upon your research I would like to see what its doing. I am running factory settings, 130 ash, 1deg hyst, love controller. In early november, had ash at 125, as fire looked low,but went back to 130 in early december.

Good to know. Looks like we have about same load on similar boilers.
