Circulators that you can set GPM
I am having a new Alpine 80 installed today to replace the way oversized boiler that was installed about a year ago. Having been doing a lot of reading and research and feel somewhat up to speed. One of the things I would like to do is set up the P/S flows properly as I understand the way they should be. My plumber came over yesterday with the new boiler. I talked to him about primary and zone flows and he said I just used whatever pump comes with the boiler and uses 007's for each zone. From what I have read you want D/T's on the primary of 30-35* and the zones should be 20* for best chance of operating in the condensing mode more often.The Alpine manual does have a chart showing required flow for a given D/T. I realize that this is at max output and will be less as the boiler mods down. I have one Taco Bumble Bee that I will use in one of the 3 zones I have utilizing D/T to set flows. The primary however I want to set a fixed GPM and know that is what I have. Are there any pumps that you can set the actual GPM? The Bumble Bee does not seem to be able to do this.
