Cold vortex and loop temp.
Its been dam cold here in Southwestern Ontario much the same air mass as Michigan. The heat-pump has been working real hard. The shop is kept at 18 Deg. C.
You are right the loop field is cold inlet 3.2 Deg. C. and returning 1.9 Deg. C.
With all the wind and a leaky shop the electric bill is quiet something even though I have a economical heating method.
Really glad I'm not with the oil-man
