I always thought my Rutland probe thermometer probably was not too accurate, but it was a good guide to boiler performance. Most of my burns with dry pine were in the 500-600F range.
Just got a K type probe thermocouple, tested it against another temp sensor on the return line to my boiler control. The boiler control sensor read 175F, and the new probe read 176F. So I figure the new probe likely is pretty accurate.
Boiler was in high burn, the Rutland read 600F, pulled it and inserted the new probe 3" into the 6" flue, and the reading was 465F. Assuming this is pretty accurate, I probably can reinterpret my prior burns to be mostly in the 350-475F range. I confess that I always thought my burn temps were high compared to others; now likely that my burn temps are right in the ball park of the experiences of many. I also feel some comfort now knowing that the Tarm probably is more efficient than I thought.
