my first question would be....when you cant get your house over 70 degrees in the extreme cold, does your OWB ever get to the set temp and the blower shut off?

if the answer is yes then you could try turning up the off and  on temps some. perhaps you need to have a larger heat exchanger in your furnace?

it is obvious that in the extreme cold you are unable  to deliver enough btu to the home to compensate for the btu losses

first thing to check is...is your OWB capable of producing the needed btu and are your lines and exchanger capable of delivering those btu

Try bumping your on off temps to 180 off and 170 on and see what happens. Thats where mine is set. Seems to be perfect for me. Every set up is somewhat different i guess.

If the owb is keeping up like Willie mentioned, I would check the temp drop on the return line. If your pump is under sized a larger hx won't help. If the return is not too cold then you may need a larger hx or just bumping up the owb temp may work.
