My philosophy is to let things alone as much as possible, if it aint broke don’t fix it. I compromised and set my aquastat to 180 high – 150 low and let it there all year long. Draft is good so the main air is wide open and the little blower is about quarter to a third open. The KA6 is a bit oversize for the load I put on it so my coal feed is cut back a little, I may have an extra inch of dead ash than what is called for by the folks at Keystoker but it seems to work fine for me. I don’t touch the feed rate – ever. My timer is the old Keystoker type, no pins, but it runs the stoker for a little less than a minute every 15. My summer coal consumption is about 15 pounds per day. This has been consistent since I started using the KA6 and even when I burned buckwheat and now rice there was no discernable difference in the amount burned per day.
1975gt750, I see your in NH you guys are still making heat, I know I am here in PA. When I look at my consumption spreadsheet I see that my hot water only months are May through September.
You said there was not much difference in the amount you burned from buck to rice, did you have to adjust the combustion air when changing coal size or did you use the same setting? I have a different stove than you, I have a Keystoker 90 but am going to switch to buck from rice. Just wondering if I need to cut back on air. Keystoker says I can leave it at 1/2 open which is factory setting.
