Need advice on using Taco Bumblebee pump on new boiler installatio
Hi.
I am thinking of using a Taco Bumblebee pump on the primary (boiler) side of a new Alpine installation.
It seems that it wiould allow me to set the high Delta/T on the boiler I want and maintain it throughout changes in modulation and changes in the secondary.
What concerns me is keeping adequate flow through the primary at all times. As the D/T lowers the pump GPM should lower and perhaps get to a point where there is not adequate flow to scrub off the heat on the HX. Does anyone have experience with these pumps? Can I program a mim flow rate to not go below?
Thanks for any advice,
Tom
