130' run is 1 inch pex adequate?

Solution

So what is the solution then? 4 lines?

The best posible solution is to run 2 loops and pumps a 1" to your house and a seporate 1 1/2 or 2" to the pool.

Also be careful whe you choose you pool HX the common stainless steel one you see are far underrated and dont perform well.

I have a bypass in my pool return line that I have used for solar hear. Maybe I should bypass the pool water to the boiler. I could could get good boiler flow right at the unit and pipe for pool water is cheap.

Might lose the heat I put into the water in the ground from the 1-1/2 inch pool pipe.

I wouldnt recomend that just install a good tube and shell HX.

Should have been more clear. I didn't mean pool water in boiler. I meant pool water to boiler location, to a shell and tube HX placed right near the boiler.

Yes,you want an oversized exchanger,as many times,the OWB temps are lagging between 150-170 degrees.Most are rated at 180 degrees.besides if your exchangers are bigger,you can run the OWB cooler,which will save a ton of wood,and give faster recovery times.

Check the ratings: Heil rates their coils down to 130 deg. 1 1/2 X sizing works good...DO YOUR HEAT LOSS FIRST!
1" PEX will flow 4-8 GPM, not counting fittings, etc.
At least you're using the ole noggin and piping it primary/secondary style.
