I'M Not! It was 0°F this morning now it is up to 2°. My circa 1911 house is 71°inside. The boiler temp. is all the way up to 150°!, highest so far. The house is not unusually tight either. Viessmann vitola with early generation trimatic. Indoor sensor is not hooked up yet, but at least it is hung on the wall and the wire is run.
