Last night, it started blinking around 1:30 AM, so I turned it off for night. Outdoor Temps were dropping slowly..
Used two 900W space heaters all night in the den. 1.8 KWh = 6142 BTUh. It was a little cool in there.
Woke up to a COLD day. I didn't think today's forecast temperatures would allow for ANY use of the Sanyo..
But, when the outside air soared up to 6.4 deg F this morning, I turned on the Sanyo..
It's still heating the Den, using 700 to 800 watts.. (See history chart below).
It's on the north side of the house, so there is Never any sun light near the old Sanyo.
I really don't understand why this thing is working so well, during some really cold days..
For the Boston area, this is really cold. Yesterday we shoveled out in a -20F windchill. Strange times we live in..
