I just cleaned my Econoburn 200 Friday. Today I installed a Thermocouple with PID digital display. I put the thermo couple in the flue outlet on the back of the boiler.
I had been using a magnetic gauge about 1' up from the outlet.
When the magnetic external read just under 250 the internal thermocouple read 625.
I have seen the magnetic one at 300 so internal temps will be higher than 625 at that point.
My fan butterfly is full open, does that reduce flue temp if I close it down a little?
What does that do to output if I close down the primary air a little?
The boiler will burn 90lbs of oak in less than 3 hours. I am calculating 4000-4200 btu's per lb of wood to storage. Would reduced air flow net more btu to storage if I reduce flue temp?
