What's an "Average Correction Factor"?
We researched Jaga low temperature ( and low water ) radiators, advertised to operate at 104 degrees, with the ability to use higher temperatures.
There's a series of charts labeled "Average Correction Factors" and "Mean Temperatures By 1 GPM - Reference: 160°F (71°C)"

Since the hot water source we're considering ( gas absorption geo-thermal ) produces 140 degree water, the numbers just look confusing. What's to be gained going from 104 to140, or to 160? Does it make a significant difference? What's getting "corrected"?
If a heat pump system is rated at 132K BTU/Hr, is that the upper limit of the heat that it can deliver no matter what the water temperature, or the size, number, or design of the radiators used?
