Taco wb 2400 or 0013 pump?
« on: January 22, 2012, 07:22:08 AM »
I recently did some head calculations and flow rates for my system and i have 30ft of head and need 6 to 8 gpm for my system. I have 100ft of 3/4 copper baseboards and calculated for my elbows 220ft of 1" pex  a heat echanger for dhw and a zone valve. All these pipes and 65000 btu  put me at these figures. I currently use a taco 009 and i calculated its only pumping 2 or 3 gpm. Would the 0013 or  wb2400 be a better choice? My return temp is 20 to 25 less than supply right now and would like to get that to 10 or 15. Possibly reducing wood consumption.

I just looked at my accessory catalog.  009 is a work horse but slow, only about 8 gpm.  Head height of 34'  I use one to feed my house with 1" PEX to a air exchanger only.  Works great for my needs.  I use 0014 on 1 1/4" line feeding a manifold assembly that supplies my greenhouses.  That pushes 32 gallons with head height of 22'.  I don't have any knowledge on the WB2400.  I wonder if adding another 009 in the home somewhere inline as a booster pump would be a viable option??  I wouldn't think it could hurt.   :-\

A little more info or a piping diagram would help to better answer your question. 6-8 gpm needs to be more accurate, cause thats a big difference in flow. Is the slant fin 1 long continuous loop? 20 degree differential is good and optimum for efficiency. What does the zone valve serve. Is there a heat exchanger?

My system is pretty much plumbed in like diagram in central boilers booklet for direct to baseboard configuration.
From the owb to domestic hot water heat exchanger to 3 way zone valve to control the temp in the house to the baseboard registers then back out to the owb. Pretty simple setup. But like many i always want to see if i can impove my system.
6 gallons a minute is what i would be trying to shoot for with a 013 or wb2400.
