Hey guys, wonder if anyone might have some advice for me on this.
I am looking to get a replacement pump and/or cartridge on hand so I can be ready when the Taco 009 goes out. I am in my second season, burning 7ish months a year. I run the pump one hour a day when the E-Classic 1450 is shut down. Hope the pump will last a long time but want to be ready.
Size. My run is 30' from pump to a 40 plate hx, that's all. Essentially no elevation change. I am thinking my dealer upsold me on a bigger pump than I need just to milk more $ out of me. What do you guys think? I am not an expert on head calculations.
Thinking I might get an 007 for the backup, and perhaps a spare cartridge for the 009 to have on hand. I'm not afraid to spend this money as "insurance," but obviously don't want to spend more than I have to.
Any advice will be much appreciated!

What are you using for underground line? Larger line size can use a smaller pump.
-
1" thermopex...not sure if that is considered larger or not?

I am pretty sure the Central Boiler manual says not to use that pump with a short run like you have. It has been a while since I read one though so I could be wrong. I would suggest pulling it and only using it as a backup. I wouldn't even bother getting a spare cartridge for it. You are better off putting the money towards a proper sized pump.
An 007 would probably work fine but I would go with an 0015 (used to be 00R) if you prefer to stay with Taco or if you don't care about brand, a Grundfos UPS15-58. There are a lot of other pump options too if you wanted to use another brand or model.

It is far better to have a complete second pump as a backup than to have to change a cartridge out in the middle of the coldest night. Get spare gaskets too, if the 2nd pump doesn't already come with them.
-
I'd vote for a Grundfos UPS 15-58 or B&G NRF 22. Got a little more push than the 007 and more gpm than the 009.
-
I just put in a grundfos 15-55f. It is nice to see the amps and gpm for trouble shooting problems. Also it is energy savings device. Tax deduction!!!

Thank you all for your help. I didn't see anything about the 009 specifically in the 1450's manual. I agree that there is probably a better pump for my application though and will take your suggestions about pulling the 009 and using it as a backup.
Sounds like the 15-58 is a popular choice. Price is not bad ($90), just a little more than the Taco 0015 ($83), and the NRF 22 ($79). Not to start a brand war but can anyone give me some pros and cons for these three brands besides slight price difference? One brand fail on you while another runs strong?
Thanks again

I built my first OWB fifteen years ago, I’m still using my original pump but in a different application, a Grundfos 26-99. Nuff said?

Grundfos 26-99s are really great pumps, True workhorses.
But question: why do some places list the 26-99 by its number designation but other places call it the "Grundfos Super Brute?" Same thing? :-\

Far as I know it is, I could be wrong though….I’ve googled 26-99 before and I’ve had it turn up as both

I am using my original taco 0011 that went into operation in 2002, I turn it off in the spring and turn it on in the fall, However,in recent applications I have been using grundfos pumps at my sons and my other property as I have found a local supplier that is easy to deal with. I personally think both these makes of pumps work good. I don't really know what the power consumption is on these pumps of equal size but I would trust either brand equally?

It is on page 11. I think they used to have a length listed in other manuals or maybe it was what someone posted that CB told them.
Pump Selection
The Taco 009 is a medium flow, high head pressure
pump that requires an adequate amount of pressure on
the outlet side to prevent the motor from overloading.
With the piping you said you have, you will not have adequate pressure on the outlet.

It is pretty much the same as a Chevy vs Ford vs Dodge type question. I personally would use the Grundfos 1st, Taco 2nd. (for this size pump)

RSI thanks for pointing me to page 11. In case others are interested now or in the future, here's what it says about the 007 too:
Pump Selection
The Taco 009 is a medium flow, high head pressure pump that requires an adequate amount of pressure on the outlet side to prevent the motor from overloading.
The Taco 007 is a medium to high flow, low head pressure pump. In a very low-resistance system (e.g., short length of supply and return lines, only a flat plate heat exchanger, etc.), the 007 pump may need to be mounted lower near the base of the furnace to prevent cavitation at high water temperatures.
My supply/return run sweeps out of the boiler (man that was a pain), goes 24 ft, three elbows before the thermostatic valve, a wye strainer, 40-plate Hx, then back on the same route. About 30 ft each way. I was thinking this could be considered a short length of supply and return and only a flat plate Hx. This is why I thought the 007 sounded like a better fit per the manual. I didn't read the manual before I bought the 1450, should have, but trusted the dealer to set me up properly.
Still trying to figure out why the 009 was chosen. Must be for the lower flow. The load on the DHW side of the hx is fairly low I suppose, house is very well insulated and combined with the 800sf radiant slab I don't require too many BTU's compared to other houses.
Anyway I'm leaning toward the Grundfos. One I get it running I'll report back on how it works with my system.
