It got pretty chilly here last night.. Down to about 11F. Since midnight, the average has been 13.6 °F. Climatological Data
But, now that we are heating the den (with Sanyo#2), staying at 20C all night cost us $3.18 (9 hours : 14.8kWh)
$3.18 wouldn't buy one gallon of oil.
I think the units are both using about 850watts each on average, when it's this cold.
The systems seem to be balanced somehow.
Our big peak of the day was likely this morning at around 7AM @ 3.37 kW
meaning 1.685 kW used by each unit. (Each drawing 7 amps)!
My wife turned them up to 21C at around 7AM, so when I got up it was nice!
I don't think it ever dropped below 20C (68F) all night.

It sure was nice to wake up to a nice 21C house this morning!
Knowing that we didn't burn 4 gallons of oil ($3.89/gal) last night, priceless!

My experience with Sanyo#1 has shown it starts falling behind when
the outdoors gets down under 8-10 deg F.
But, now that we have dual Sanyos, not keeping up with the losses might
not occur until it drops down under 4 or 5 deg F..
