Timer is 15 minute timer set for 30 seconds. Aquastat is 160 lo 180 hi 20 diff . Thermostat is set at 65 but the heat from the basement keeps the house at 74. I was in the basement cleaning up all day Saturday and Sunday. The furnace only ran off the timer. The temperature of the water never dropped and the house never called for heat. It was a warm weekend though. I burned 80 lbs between those two days.

I am not sure exactly how much I am burning but its around 20 - 25 lbs a day on a very low use day. (read that a warm day outside with little system demand)

This was after much help from Jay on settings! so he'll get you fixed up.

I know one thing that helped me was 10 on the differential. I was at 15 also.

I am running 140 - 175 on the aquastat.

Make sure your baro damper is set correctly. .04 at the flue and .02 over the fire.

Good luck!

That's what I'm working on now. I sold my manometer a little while back and now I'm looking into getting another one.

I am running 2 min 1 hr feed rate is 3 teeth Auqastat set at 140f low 180f high 10 diff T stat is a 7day digital 5am 71 11am 69 5pm 69 11pm 71 with these setting Iam burning on the timer 15lbs a day 3 teeth is 7.5lbs the timer runs for
2 hr a day when the heat kicks on it will burn 20.4 lbs a day I started it up on 10-10-08 as of yesterday i have burned 408lbs of coal the house called for heat 11 times since it was started The stack temps on idle is 95F when it heats the
temps will be 150f to 170f To heat the water from 140f to 170f it takes 23 mins then the T stat kicks off The house

is happy you may want to try a 1 hr timer and set the auqastat at 140 low to 180high with a 10 diff I was having a 4 to 5 degree overshoot on the t stat but i had it set on 3 span i knock it to 2span and the overshoot is 2 to 3 degrees i may drop it to 1 span and see what it does You may want to play around a little but then again you are using a highboy which
holds 73 gals of water compar to my 40gal so you will use more coal to heat the boiler plus your water coil is or should be a 7 gal mine is 5 gal Oh by the way I missed you when you where down at Steve's small world that you girls farther was one of Steves old racing buddy's anyway let me know how or if you try new setting

If you're overshooting your tstat, have you measured the miliamps of current your circulating system uses and adjusted your heat anticipator accordingly? Or don't you have a heat anticipator model?

I don't yet have a domestic coil installed, there is just a block off plate on the front of the boiler. I'm not sure what a heat anticipator is but if it's on the thermostat I'm sure mine doesn't have one as it is an old twisty mercury-switch style. I'd like to get a 1 hour timer but I can't seem to find one yet. Does burning buckwheat affect how much coal is used at all? I need more coal and I can get buck a little cheaper than rice so before I fill up the bin I need to make a decision on that. I'll change up the aquastat settings and see what happens. Thanks for all the help

That reply was for coal berner. All the old style round Honeywell T87F had a heat anticipator.

You need a good chimney installed and you need a baro put on your pipe and get rid of the MHD and shell I go on :P

you do have a water coil in the other boiler top right with buck I think you will use less coal plus it is cleaner less fines
And you can always get it you do need to run more air to burn buck and you can slow the feed rate down more then you can with rice buck takes longer to burn who is charging more for Rice then buck up there how big is your auger or augers
are you running it to the bin or a drum

No water coil at all. I just transferred the flat block off plate from the old boiler to the new one. The last time I was up Harmony they said they were very low on rice so it was $10 a ton more and you had to call ahead for it. Everything else was the same price and pickup as much as you want.

Right now the augers I have are 1 1/2" inside a 2" pipe. It's only coming out of the side of the furnace about 18" and going into a drum right now. I should get the bin wrapped up this week but that's going to be in the same spot cause I like to keep the auger short. The buck looks so much cleaner and it works better in a pinch in my Surdair stove than the rice does. I think I'm going to go with that when I fill up the bin.
