So......

No more mortar nozzles for the Optimizer 250 / 350 Series.....

5/8" Carbon Steel Plate nozzles only??

Would LOVE some recommendations for the best method to position and secure this new nozzle which I have never used.

When I first installed my pipping I use Shark bites but have since replaced all but 2 of them with crimp rings.  The 2 still in the system will also be replaced when the leak.

OK, I'm getting 1" Thermopex from a local dealer.  $1564 for 100' after taxes.  That seems like more than I've paid in the past, but who knows what prices have done ever since the craziness of the past 3 years. 

Does 1" Thermopex use regular 1" PEX fittings?  Can I use 1" Sharkbites or 1" cinch rings on regular 1" fittings or is it a special size and need different fittings?

Had a trouble free season.  I learned how to shut it down for a week due to warm weather and start it up in a couple hours. There is a tiny air leak someplace and the fire just keeps smoldering if I throw in a chunk or 2 every couple of days.  Only a couple shark bites still in the system only because they have not leaked like all the rest.   :thumbup:

Insulate you will regret not doing it later.

I realize it would be resting on the bottom, but the actual amount of contact is minimal and the heat transfer from PEX through PVC and into the ground wouldn't be a ton.
I disagree, but I have no data to go by. That small bit of contact surface area will add up in a hurry.

Sounds like you're going to go with thermopex anyway.

I'll probably just wind up using Thermopex so I can get it locally.  I'll be fine using the regular 1" stuff.  I don't have a need for high BTU transfer, just maintaining a radiant slab in a well-insulated house.

I would not think that would be a good idea. Your pex will not be suspended in the middle of an air gap, it will be resting on the bottom of the PVC, which will be touching the ground and sucking your heat away.
