recirculating pump for a boiler
Posted by bill on March 08, 2004 at 02:31:18:
Does the speed have anything to do with the pressure in a boiler system. I had someone come in and put a new recirculating pump in for my boiler but the pressure used to be only about 12 psi in the system now it wants to go above 30 psi and that is what the safety blow off valve is set at. The new pump speed is almost twice what the old one was.
