circ, sizing rules of thumb

Dan Peel

There are always shortcuts.....
Residential? Up to 6 loop in typical scenario I'll look to the 3speed 15-58 grundfos or a 007 Taco with a rheostat. Over 6 look at the GPM you need - eaven freebees need design. Grondfos 26-64 or Taco 009 or 10 could work. Tastes like bait........ Dan

Is there a rules of thumb

to sizing circulators for radiant floor manifolds? My software does it for me but I was just given a charity job where Wirsbo donated the materials and manifolds. The largest set of manifolds are 8 loops of 1/2 in pex, all below 300 feet. Other manifolds are smaller. I could run the softare and back intyo the information, but want to know if there's a way to do it on this information.
