The E+ results of this baseboard heater autosizing indicate 1.43 GPM for 435 BTUH * F? What is the F? I am used to baseboard being sized at BTUH per linear foot like this other photo of a runtal.
How do i get the actual total size of the heater needed? If i knew i needed 3.6 MBH i would specify 6' of UF-2, but i don't understand how to use the E+ report to match equipment.
