I recently got a 50 plate 3X8 heat exchanger with 3/4" fittings on it. My pex tubing is at 1". How big of an issue is this going to be going down from 1" to 3/4" for this? I understand it is limiting the flow, but how much is the flow limited by the plate exchanger anyways, since it goes down to much less than 3/4" through the plate. There is a 5X12 50 plate exchanger with 1" fittings on it that I could possible acquire, but it won't be here until about halfway through the season, and I'd rather have this installed before starting up the boiler.

It's more about the flow rate, not the pipe size. Actually the ID of that 1" pex is probably about the same as the 3/4 HX connection.
