ReplyYeah, I'm pretty sure it's at the highest speed. The original installation used a smaller pump but we went to this one to try and increase temps by increasing flow.

A hydronics tech should be able to purge air from a loop, no DIY.

Are the zones that are not working well at the highest point?

Is the pump feeling HOT, not warm but too hot to keep your hand on for more than 1-2 sec?

Are any of the tubes getting warm, maybe a few runs are air locked, or pump is bad. There should be temp gauges on supply and return, do u know any temps? 300 feet is too much, 250 is max.

When you say "get up to temperature," can you explain what that means? Up from where?
One pump? 13x300' loops?
These insufficient zones, in rooms the furthest away from the boiler for those floors?
Boiler make & model? Modern high zoot boiler (to match the house... And if so, why no ECM pump)? Temp setting? Water temp programmable by zone? Reset setting?
