Weather has been mild here and very consistent temperature wise so I decided to try a test. Day one, I did a 4 split fire using the stove blower on about medium-low speed and timed the rise of house temps around the corner in the hallway where the thermostat resides. It took 3 hrs to get a +2deg rise from startup of the stove. Today, I did the same using just the ecofan. It took half the time to raise the hall temps +2 degrees. Interesting. Next test will have to wait until later in the week. I will try it with no fans to see if the temp rise is due to pure convection or not.
