They are probably way too big.
How much is the price?

You're looking at 4.9 amps for the 2400-50. Could burn up some savings pretty quickly. 
Around 2 amps for the 0011. a 0015 (a common size used) is less than one amp.
How much flow do you actually need? What size piping?

And from what you said earlier it's 100' one way? What heat exchangers or heat load are you supplying water to? Trying to calculate what flow is needed. I would feel there isn't a one size fits all pump, and the pump you described sounds large for 1" pex.

There are new  3 speed 26-99 Grundfos on eBay right now for $153. Would beat an 0011.
You might could get by with a new 15-58 or B&G NRF-25 for less than $100. Depends on the CFM of the blowers you've got the coils in.

I would go with Grundfos unless you prefer Taco for some reason.
15-58 may be large enough or 26-99 are about the same sizes as the 0015 (15-58) and 0011 (26-99)

200ft total loop of 1" is about at the top of the spectrum for a 15-58 with an exchanger to keep full flow. The B&G NRF-25 has just a bit more umph, but may be harder to source. If you can afford to lose a little flow, the 15-58 is cheap and sips electricity, should get you 5-6 GPM. If you need the full 7-8 GPM that 1" can carry, I recommend the Grundfos 26-99
