PEX spacing is extremely important when looking into this also

While you're investigating PEX diameters, you might also want to consider 5/8"... it's not so common but is available. It has almost 2x the volume per foot.

Might also consider bending diameters for various sizes of PEX.

There are some strategies for dealing with small spacing and bending diameters.

Keep in mind that most advice for sizing/spacing assumes that you will use a fossil fuel boiler.

It is so rare that you will find advice for low temperature heating, that you should post any resources you come across that address it.

PEX sizing...

Happy Hunting,

P.S.: Just came acros this link. Good discussion, good advice, but all the folks are using electric or fossil fuel boilers, so your spacing will need to be closer, if you are going low-temp heating.
