On a typical coldest day of the year I burn 125 lbs +/-. A mild day less than 25 lbs.

How big is your house.

is the 25lbs during the summer for hot water or do you mean on mild winter days?

Heating about 1800 sq. ft. on four zones. Well insulated with double glass windows, about half argon filled. Also sometimes heat a 1000 sq ft shop. 25 lbs in a mild winter day, i.e. no wind, sunny and above freezing for the entire 24 hours. Summertime domestic hot water is also about 25 lbs a day, maybe a little less. It's high because I have a lot of piping loss between the boiler and the indirect hot water heater plus the idle fire losses.

I've read this report previously, but I like Yanche's take on things from his engineering standpoint.

The Axeman-Anderson boiler is an engineering marvel to this day, even with it's imperfections.

I would personally LOVE to have one, but this house that I live in now doesn't deserve an Axeman-Anderson!

Maybe the house doesn't, but you do! :)

Yanche,

Thanks for posting this stuff. I found it very interesting. I like the old lingo used.

112 lbs per day = 3360 lbs for a month. So, $300 ish a month at $200 per. Imagine what it would cost for oil or gas to heat a no doubt not well insulated house like that!

I was pleasantly surprised about the flue gas temp data. I too see a tad over 400F on an internal probe, which I thought was really high. I assumed this was due to me having to force more that the normal amount of air through the fire with the finer than ideal coal I'm burning.

Thanks again,.

A gross stack temperature of 400F was outstanding compared to oil burning boilers at that time. My oil boiler is almost 30 years newer than the AA in this study and it runs a 500F gross stack temperature.
