Economic balance point cut over question…
Just went DF. New unit keeping the house cool without humidity this summer. Thanks to all!
New 14 SEER 4 ton Amana AZ 410A heat pump with coil.
I have set the cut over to change over to oil heat at 20* outdoor temp.
Based on my calculations, with a COP of 2.65 at 20* - oil at 3.85 a gallon and .21 KWH
#2 Oil needs to plummet to roughly 2.65 a gallon to begin considering bring the cut over upwards to 25* or 30*
Is my math on?
I used many of the online calculators on this site so I think I am close to reasonable number.
