I go with what Corrosionman once mentioned. Something to the effect that if it burns, it has BTU's, might as well put the heat in the house.
That's why I keep my 'Ol Harman in the basement. If it fits through the door, it burns!

COAL DELIVERY!!!

I got the bin ready. put the chains on, pulled the barrel out, removed the front coal port and put the slats in.

Don have you done a comparison by HDDs or usage without domestic hot water?

I feel like domestic really takes more than I realize....

I don't know about the HDDs but the DHW is 15,000 to 30,000 BTU when its running.

Are you saying that your stoker ran 50% of every day? That seems like a lot of time for the weather not being anything extreme?

It was cold and windy the first half of that week. When you run a lower feed rate, the stoker has to run longer to push enough coal. Theoretically, this runs the system further up the efficiency curve.

50's and 60's for highs this week. Let's see how we did!
IMG_0001.JPG

4560.0 - 4509.6 = 50.4 hours, 7.2 hours per day.

Wow, that's a big drop from last weeks 503.6 pounds!

While I was taking out the ashes, a BIG Squall blew in with super high winds! :o
Chimney draft went up to -.075 with the baro all the way open! :what:
Thats why you connect one of these gauges backwards. If this was hooked up to the minus side it would have sucked the juice out of the gauge.

How long does your boiler usually run with a standard heatcall?

I've totally given up on using the TT terminals. I think they cause coal boilers to overshoot. My opinion is it's better to just let them maintain a water temp and forget about what else it going on. I just adjust the anticipator on my T-stat so that it's sure to run a little bit after the boiler hits setpoint and so final temp is near setpoint.

I like your idea of the inkbird, it's nice too because you can hook up a timer to run through the NC terminal to prevent timer cycles following a heat call.

I don't know for sure but probably 10 to 20 minutes.

I just used the Inbirds on GJ because they were already wired in and they have given me no problems over the years, and I'm lazy. :lol:

Yesterday afternoon I finally got brave enough to turn the timer OFF. So far, so good!

That has been my experience as well. If you want to vary the boiler temperature according to load, use some sort of reset control.

Especially once warmer weather hits, then you get a heat call in the early morning and a bunch of timer skips and then outfires....

Deep pot stokers , they can keep a fire for 8-or 10 hours . 3 of us here hav'nt used a timer in 5 years , np .

Different topic , large producer called Friday , mine prices are dropping now . FYI , for bulk buyers .
