Title: Taco 009 replacement
Post by: jrhirschey on January 14, 2015, 11:32:58 AM: I have an e 1450 running thru 140' of thermopex one way to an oil fired boiler core and back. There are 2 1" copper 90s and 2 3/4 blackiron 90s also 4 ball valves 2 1" and 2 3/4" full port. Also have the CB thermostatic valve piped in. My taco 009 is on the WB and I wood like to get a better pump with more flow.
Does any one have some suggestions or would another circ in series work also. I have a spare up 15 42

Thanks
Jon

I've got about 100' of 1" pex between my owb and my hx with an Alpha 15-55 showing 6 gpm in high. I wanted to bump it up a bit so yesterday ordered another 15-55 and just installed it in series with the existing, one on either side of the hx. The first pump is showing 11 gpm now and new one is at 8 gpm and both are at 43 watt. I don't know how these pumps calculate gpm, but they are both doing the same even though they read different.
Anyways, happy camper, I've got more flow and now have a backup already installed in case one fails. I will just run one on low speed during the summer to keep some circulation going. I'll also start playing with pump speeds to see what happens.

RSI, why does the fact that the pump is a 3 speed affect why it should be at the burner or not?
Thanks!
Nick
