Modulating Boiler Question

$
0
0
So the minimum input of my Viessmann 100w B1HA is about 36,000 btu/h. (LP)

My Aquacoil outputs about 37,000 btu/h at 140 degree water

Is it a complete waste for me to have my heating curve set for less than 140 degrees or am I missing something? If the boiler is going to output 36,000 btu at the minimum and anything less then 140 my aquacoil won't be producing enough btu/h am I just wasting fuel?

Thank you for the help!
