I am putting in an infloor Wirsbo 1/2in hepex plus system with 17 300 ft loops.
What is a ballpark estimate of costs for the pumps, fittlings, and other hardware
to run these 17 loops?
Thanks.

You got about 3K in tubing. The rest depends on what your doing... Staple up,plates,high mass, how your zoning,controlling, etc. lotsa details needed.
You must have a design,because you know it is 17 loops, go to pexsupply.com & price the parts.
If you don't have a design, well thats where you should start.
There must be a general formula for a range of cost for 17 loops for the motors, valves, etc. I am not interested in boiler cost on this. I'm just trying to get an idea. The pex cost is about $3500 (hepex plus).
eg, would an estimate be 1-3,000? or more?
No formula. You need to know the design, figure out parts needed and then get local pricing.
Way too many variables. How many zones/thermostats? (Not necessarily the same as the number of loops.) Are you using a seperate pump for each zone, or using controllers to share pumps over more than one zone? What type of pump - iron or bronze? Don't forget the valves, expansion tank, backflow preventer, air eliminator, manifolds and 1-1/4" (or larger) copper piping and fittings to hook everything into the boiler -- they'll cost as much as the pumps, etc. How are you running your piping -- underfloor with/without fins or in quick-trak? You can't even get a rough guess until you have a design that specs all this out. I'm not even sure how you can know how much/what size pex you really need until you've had a heat loss calc and design done. Your supplier should be able to put this all together for you.

You need a heat loss and a design! I am going threw the same thing now, start with a heat loss then design the system to meet the needs.
Pushing 1/2" to 300' loops is a bit much, 250' max. loops is more like it.
You will be much happier with the end results with the proper planning.
