Any one ever use a wall thermostat with their coal stoker,if so do they work very good or is the heat up and down. right now i have stoker set on #20 and blower on auto works good but was wondering if i should install the wall thermostat

im new to burning coal and i installed a keystoker koker this fall and i run it from a thermostat. I have the koker in the basement (that i am working on finishing) and the thermostat is on the first floor. i have a digital 5-2 programable and i love the way that it keeps the house warm. I have the blower set on automatic and it only kicks on a few times a day. i usually end up with a 2 degree overswing in temp but i think that is pretty good for solid fuel heat! I know that every house and setup is different but im only burning about 20lbs of coal a day, and that is my only source of heat.

I use a Honeywell RTH6350 programmable I got from Lowes. It has a smart feature that learns the heating cycles of the house and I get almost no overshoot. It holds temps to less than 1 degree +/-. I programmed it for 68* at night, 70* in the am and 72* in the early evening.

i would like to use a digital rather than the bi-metallic slider that i am using with my mag stoker, but the ones i have looked at all require 24V power from the furnace circuit which i don't have. i measured the voltage coming off the harman controller at 7 v. it wouldn't even need to be programmable, i was looking at the RTH111B, but even that says it works off the 24V furnace circuit.

I believe that the voltage is for the relay in the appliance only, so whether its 24v or 7v it shouldn't matter. Although, I wouldn't wire any higher voltage to it than 24v. Try it, or you may want to verify this with a heat installer before you do anything. :D

How about a schematic or line drawing to help us understand what you are trying to do. I just installed a RIB (Relay in a Box) to control a fan that takes air from the Keystoker 90 and blows it through the rest of the house. It is hooked up to the Cool side of my thermostat, and so far upstairs is right on the money as the delta T of the cold contact is like .7 degrees right up the alley of the way coal responds.
