007e replacement for B&G100?

mjstraw

Gravity conversion system with B&G100 circulator.  The Taco 0010 has a similar pump curve.  Not sure where on the curve the 100 is operating.

Would an 007e be a good substitute, too?

How many square feet of radiation is on that system?

Not sure.  I'll go off and measure.

Is there a way to compute EDR for a radiator beside using Dan's "every darn radiator" book?  They are 5 column thin tube rads of various dimensions.

@mjstraw

you measure the radiator height, width and number of sections and number of tubes. You can find a chart in the "Burnham Heating Helper" on line if you cannot find the information on this site.

Either way, you need two things to find the right pump flow in gallons/min (which you will know after you calculate the rad sizes) and the systems head loss
