Well, what was initially supposed to be 4 to 5 days of high 60's to low 70's is now proving out to be far more consecutive days than that, and consistent 70's to boot. The good news is that so far I have not lost my fire, even without a hold fire timer. The only things keeping it firing are showers and laundry, and that may prove to be just enough, though for how long going forward is still an open question. The next time I feed the Coal Gun I should get a good picture of its consumption over the past several days. So far it has not consumed enough coal to inspire me to load it up. Perhaps tomorrow after work I'll top her off and tally up what will be 4 days of running without a feeding. The way it looks though, it could go another 4 days or more beyond that before feeding becomes a real necessity.

Too bad you never got to run that fancy 520 through the new & improved chimney. Did you put an hour meter on the stoker yet?

Yeah! Too bad. This one is really set up good. I think that it could be lowered to 30 seconds and still keep fire. You can see the coal glowing in there whenever you open the door and the fire comes back too life real quick. Nope haven't gotten around to the meter yet. Some things take time. ;) How well do you do on the fuel economy? You have a good draft. Could you go down to 1 minute per hour. I think the deeper shaped pot is the reason for my success :)

I think my timer is set for 1.5 minutes every 30 minutes. I had it set for 2 minutes out of 30, but this year's coal seems to hold a fire really well so I backed it down on Saturday. It works out to about 12 lbs per day for timer cycles.

I'm sure it helps.

We're breaking (make that shattering) March all time high temperature records here in Ohio. Now we will have a string of days reaching into the 80's, in March no less.

Yep, same here way over in Pa. but they are saying the high 50s by Sun. but the lows will be no where near a frost if they are right. I'm starting to get tired of yard work already.

I fed my AHS S130 Coal Gun today, and I can now confirm that I have duplicated Yanche's figure of 17 to 18 lbs. for near minimum daily coal consumption by the S130. Over the past five days there were a sum total of only 4 recorded "heating degree days". That's zero home heating demand in my book. The only real heat demand over the past five days was from typical laundry accumulated over roughly one week, daily showers, and dish washing for the two of us.

I added a measured 90 lbs. of coal, but then after levelling it as best I could it was noticeably a tad over full and I had a bit of a time getting the hopper lid to fully seat properly, so I easily added about 5 more lbs. of coal than I should have, and the previous filling did not take it to such a high level. Accounting for the extra 5 lbs. would mean 85 lbs. consumed over 5 full days. 90 lbs. over 5 full days is 18 lbs. per day, and 85 lbs. over 5 full days is 17 lbs. per day, so that is the consumption range I experienced.

I gave the Coal Gun another feeding today. This one was a scale weighed 70 lbs. of coal for 4 full days of running, and it took the hopper level to the same nearly over full condition as per my last filling. 70 lbs. over 4 days equals 17.5 lbs. per day. There were zero "heating degree days" experienced here within the past 4 days.

In quite good agreement with my post above, 17.5 lbs. seems to be my baseline for lowest possible daily consumption with the AHS S130 Coal Gun. That is what it needs to sustain a fire and provide for the homes DHW needs for two people.

Starting with tonight we are heading into a couple colder days going forward, so this was the last day whereby I could measure my "zero home heating demand" coal consumption (for awhile at least).

Latest update: So far for the entire month of May (through today, the 16th) our AHS S130 Coal Gun has only been eating 15.5 lbs. of coal per day on average. This lowers the bar on the minimum summertime daily average consumption of the S130 Coal Gun a bit. The only change I've made to the boiler for summer running is in dropping the SV of the thermo ash monitor (the ash grates motor control device) from 130 degrees to 120 degrees.

For the record, we took a 4 day vacation in May, and during those 4 consecutive days we had our oldest daughter come over daily to care for our chickens and also to run a single load of laundry through the washing machine (which was set on "hot") each day, so the boiler likely fired only once a day while we were on vacation due to this daily load of laundry. During our 4 vacation days there was no other daily DHW demand, such as from our typical showers, hand washed dishes, running the dishwasher, hand washing, shaving, etc... This no doubt contributed to the drop from 17.5 lbs. of coal daily to 15.5 lbs. daily.
