Several years now, the thermocouple on the boiler has crapped out on only the COLDEST day (thus far) of the year.
Again this year too -- this morning, pilot was out, and it wouldn't relight. And temp outside was 17(F)!
(Window in boiler-room is open a few inches, due to air-flow problem -- we have a fan in the pipe that goes up the chimney.)
Now, in the past, replacing the thermocouple (plumber did the work) would fix it.

Question: just wondering -- any substance to this apparent correlation between super-cold temperature and crap-out of thermouple?
question: would placing electric heater near the boiler possibly help?
Thanks!
