Ground Loop Temps in Central OH
What is the expected "average" or even "realistic optimal" horizontal closed loop temps in central Ohio throughout the year? This would be for an assumed properly sized loop for a properly sized and properly operating WSHP system. For example, in the last two weeks, with average/normal use, the EWT has been 54.8F. Does anyone have the approximate month to month temp for the heating and cooling season for this area?
I understand there are lots of variables, for example: 20% Methanol is being used as the antifreeze solution. Close counts here...:)
